Introduction to British Standard Chain

British Standard roller chain is made in accordance with ISO 606 B, BS 228, and DIN 8187 European standards. These chains resemble standard ANSI roller chains. However, they are dimensionally different and in general do NOT operate over standard ANSI sprockets.

Components of British Standard Chain

Inner Plates
These are flat metal plates with holes through which the bush is pressed. Inner plates alternate with outer plates to form the chain.

Outer Plates
Similar to inner plates, outer plates are also flat metal plates, but they have slightly smaller holes to accommodate the bearing pin.

Rollers
Rollers are cylindrical components that sit between the inner plates. They are designed to reduce friction and wear by allowing the chain to roll smoothly over sprockets or gears.

Bearing Pins
Bearing pins are cylindrical pins that connect the inner and outer plates. They go through the bush in the inner plates and fix firmly in the outer plate to produce the articulating joint.

Bushings
Bushings are tubular components that sit inside the roller and on top of the bearing pin, between the inner plates.. They reduce friction and wear by providing a smooth surface for the roller to rotate within the inner plates.

Master Link (Connecting Link)
The master link is a specialized outer plate that has removable pins or clips, allowing for easy assembly and disassembly of the British Standard chain. It is used to connect the two ends of the chain together.

Side Plates
Some British Standard roller chains have side plates that run parallel to the inner and outer plates. These plates provide additional protection and support for the chain.

Materials of British Standard Chain

Carbon steel
Carbon steel is a widely used British standard roller chain material with high strength and wear resistance. It is widely used in central air conditioners, washing machines and other home appliances. It has high strength and can withstand large loads and impacts, but its corrosion resistance is not as good as other materials.

Alloy steel
Alloy steel is a British standard roller chain material with high hardness and good wear resistance. It is usually used in heavy-load or high-speed operation equipment, such as steel, mining, cement and other industries.
It has high hardness, strong wear resistance, and good tensile resistance, but is relatively heavy and requires greater sealing and lubrication.

Stainless steel
Stainless steel has good corrosion resistance and high strength. It is widely used in medical, food processing, chemical industry and other fields. It is suitable for places with high environmental requirements and high hygiene requirements.
It has low density and is suitable for hygienic environments and high temperature & pressure conditions.

Copper alloy
Copper alloy is an excellent British standard roller chain material with good mechanical properties and corrosion resistance at high temperatures. It is usually used in high-speed, high-temperature equipment, such as ships, aircraft, automobiles, etc.
It has high temperature resistance and good wear resistance, but it is more expensive and requires better sealing and lubrication.

Plastic
Plastic British Standard roller chains are mainly used in equipment in hygienic environments such as food processing and medicine. They not only have good corrosion resistance, but can also reduce the weight of the equipment and reduce noise. But they have low strength and cannot withstand excessive loads and impacts.

Application of British Standard Chain

Bicycles and Motorcycles

British Standard chains play a crucial role in the operation of bicycles and motorcycles. They provide efficient power transmission, enable gear shifting capabilities, and the ability to customize the riding experience in terms of gear ratios and chain length.

Agricultural Equipment

British Standard chains are utilized in agricultural machinery like tractors and irrigation systems. They help to transmit power for operations such as driving wheels, moving conveyor systems etc.

Automotive Industry

In automotive vehicles, British Standard chains are used to transmit power from the differential to the rear axle. Compared to driveshafts, chain drives are easy to design.

Industrial Machinery

Various industrial machinery, including conveyors, printing presses etc., rely on British Standard chains for power transmission and to facilitate the movement of materials/ components.

Installation of British Standard Chain

Preparation

Check equipment to ensure that general transmission requirements are correct (e.g. flexible couplings, flywheel, means of drive adjustment).
Check condition and rigidity of the shafts and bearings, particularly if there has been considerable previous service with an alternative method of transmission.Replace or correct if necessary.
Driver and driven shafts should be checked to ensure they are level and parallel to each other. This also applies to the idler shaft, if present.
Use a spirit level and adjustable comparator bar or micrometer between shafts at extreme points on each side of the drive. Correct any parallelism errors and mark a permanent data line for the adjustable shaft.
Place sprockets or respective shafts in approximate alignment and fit the keys in accordance with correct engineering practice. Do not secure keys at this stage.
Care must be taken with sprockets of split design to ensure perfect adjoining of the faces of each half. Proceed with the key fitting after the halves are finally bolted together, otherwise the key can prevent correct assembly and subsequently result in malgearing.
Verify that key heads will not project beyond the width of any chain cases.

Checking Sprocket Alignment

Accurate alignment of shafts and sprocket tooth faces provides a uniform distribution of load across the entire chain width and contributes substantially to maximum drive life.
Use a straightedge across the machined faces of the sprockets in several different positions, if possible, as a check against wobble. A nylon or similar line is a good substitute for a straightedge, particularly on longer center distances.
Should endwise “float” of shafts be present, make due allowance so that sprocket alignment is correct at the mid position of “float”.
When alignment is correct within closest practical limits, drive the keys home and take a final check on sprocket alignment.

Installation of Chain

Ensure the British Standard chain is clean and free of debris and place around the sprockets, observing instructions where matched strands are involved. In chain with two or more strands, joining is most easily accomplished at the midspan of the drive, drawing the chain ends together with a chain clamp or rope tackle block. Ensure that the strength of the drawing tackle is sufficient to hold the chain. When inserting the joining link of multi-strand chain, ensure the intermediate plates are assembled. Do not detach the drawing tackle until the link is completely assembled. When only partially inserted through the inner link, the weight of the chain on release can splay or distort unsupported bearing pins.
Adjust the chain using the data mark mentioned in the preparation section to retain shaft parallelism.

Lubrication Method of British Standard Chain

Manual Lubrication
Using an oil can, aerosol spray or brush, this method requires the lubricant to be manually added once a day or every eight running hours into the gap between the inner and outer link plate of the loose side of the British Standard chain

Oil Bath Lubrication
Here the British Standard chain is placed in an enclosure with the bottom of the chain fully immersed in a pool of oil. The correct immersion depth is important as if it’s too deep or too shallow may cause the oil to heat up resulting in oxidation of the oil.

Drip Lubrication
Oil from the oil cup is fed via wick oilers, needle oilers or drip oilers, and supplied by drip feeding. This method is only suitable for low bearing pressure drives. With quantity dependent on speed, the standard procedure is to apply 5-20 drops of oil per minute for every strand of British Standard chain.

Oil-Ring Lubrication
This method has the British Standard chain running above the oil level, with a rotating disc submerged into the lower oil level which spreads oil against the casing walls from where it runs down onto the chain via drip rails. The disc needs be mounted on both sides of the sprocket in a sealed enclosure. It should be noted that this method of chain lubrication is only effective at speeds in excess of 300 RPM.

Force-Fed Lubrication
In force-fed lubrication, an oil pump and oil feeding pipe supplies a continuous spray of oil to the inside of the lower span of British Sandard chain to ensure the circulating cooling of the chains. The spray nozzles should be situated near the gearing places of the chain and sprocket, and the number of nozzles need to be more than the amount of chain strands to make them aim at the gap of each row’s link plate.

FAQ

Q: What are the signs of excessive wear in a British Standard roller chain?

A: Excessive wear in a British Standard roller chain can manifest in several ways. Some common signs include a noisy operation, inconsistent or jerky motion, difficulty in engaging with the sprockets, or visible signs of wear and damage on the chain components. Regular inspection of the chain's pitch, roller diameter, and elongation measurement can help identify these signs and determine if the chain requires replacement.

Q: How to determine the type of British Standard chain?

A: Here are a few of measurements you will need to help determine the type of chain:
Measure the pitch – the center of one pin to the center of the next pin.
Measure the sideplate thickness and height.
Measure the roller diameter and width (distance between inner roller link sideplates).
Measure the overall pin length and diameter.

Q: What are the features of your British Standard chain?

A: Heat-Treated and Shot Peened Side Plates, Rollers, Bushings, And Pins
This not only increases the fatigue strength of the chain, but it dramatically improves the overall working life and dependability of the chain.
Factory Pre-Loaded
This dramatically reduces initial chain stretching that is common with other chains in the same price-level, thus improving sprocket life and performance.
Pre-Lubricated From The Factory
All of our roller chains are supplied with a proven high-quality lubrication that is applied at the factory level. We also provide additional roller chain lubricants to keep your chain running at its optimal performance and longest possible life.
Solid Rollers
The implementation of a solid roller has proven to increase the working life and performance of a chain. This is due to the simple fact that the roller is the primary wear part that comes in direct contact with the sprocket tooth. A split roller will deform and cause a hyper-wear effect past a certain point.
Made In Accordance With Multiple Standards
Not only is our chain made to ISO R606 standards, but it also conforms to British Standard 228 (BS 228), and Deutsches Institut für Normung (DIN) 8187 Standards.

Q: How to maintain British Standard roller chain?

A: Maintaining the performance and longevity of British standard roller chains is crucial for their efficient operation. One essential aspect of roller chain maintenance is monitoring and measuring wear and tear. This allows for timely replacements and prevents unexpected chain failures. To measure wear, start by inspecting the chain's pitch. The pitch refers to the distance between two adjacent roller pins. Use a caliper or a pitch gauge to measure this distance accurately. If the pitch exceeds the manufacturer's recommended tolerance, it indicates significant wear, and the chain should be replaced.
Next, examine the roller diameter. Rollers are the components that engage with the sprocket teeth. Using a micrometer, measure the roller diameter at various points along the chain. If the diameter falls below the specified minimum, it signifies excessive wear, and the chain should be replaced promptly.
Additionally, check for elongation in the chain. Over time, chains may stretch due to wear and load conditions. To measure elongation, select a specific number of links (e.g., ten) and measure the distance between them. If the distance exceeds the recommended limit, the chain has elongated, indicating the need for replacement.
Regular lubrication is also vital for roller chain maintenance. Ensure the chain is properly lubricated to minimize friction and wear.
By following these maintenance practices and monitoring wear and tear, you can extend the life of your roller chain, reduce downtime, and maintain optimal performance in your applications.

Q: What may cause the British Standard chain cracked or deformed?

A: Chain pitch too large or insufficient number of sprocket teeth.
Sprocket teeth have foreign bodies.
The chain climbs onto sprocket teeth too high.
Excessive chain impact load.

Q: Why does the British Standard chain make loud noise?

A: There are some possible cause of the loud noise:
Unalignment of sprockets.
Unsuitable loose side sagging.
Bad lubrication.
Chain box or bearing loose.
Excessive wear of chain or sprocket.
Incorrect selection of chain type and pitch.
Too small number of sprocket teeth.

Q: What are the uses of metric roller chains?

A: Metric roller chains are used in all types of systems — from simple to complex — and provide a strong and reliable way to transfer energy within a system. In general, metric roller chains are a great fit for conveyors, drive, food and beverage, and many other applications. You are likely to find metric roller chains in agricultural or industrial machinery, where they are often used as an efficient and powerful method of transferring energy.

Q: What are British Standard attachment chains?

A: These are roller chains that are designed and manufactured to conform to British Standards. They are used in a variety of applications, including manufacturing, processing, and agricultural machinery. British Standard attachment chains are available in various sizes and designs, including extended pins, side plates, and offset links.

Q: What is the difference between ANSI and BS chain?

A: ANSI series chain is measured in 8ths of an inch – but only the numerator of the fraction is given. For example, 4 represents 4/8″ – which can be reduced to ½” chain – and would be stamped 40. BS series chain is measured in 16ths of an inch so 8/16″ is reduced to ½”, and the chain would be stamped 08B.

Q: How to measure the elongation of the British Standard roller chain?

A: Extend the roller chain until it is taut.
Using a Vernier Caliper, measure the distance from the inside of one roller to the outside of the next. Do this a few times in different locations.
Add these numbers together and then divide by the number of times you measured (e.g. 1+1+1+1 divided by 4, or 2+2+2 divided by 3). This presents the average length between rollers.
Then, multiply this average length by the number of links in the chain. This will provide the true length of the chain.
Knowing the original chain length, you can find out the percentage of chain elongation by dividing the true length by the original chain length and then multiplying this result by 100.

Q: What is the impact of British Standard chain wear?

A: Reduced Efficiency: Elongated chains cause a loss of precision in power transmission, leading to decreased efficiency in machinery operations. This can result in higher energy consumption and decreased overall productivity.
Increased Downtime: A chain failure due to wear can lead to unexpected downtime, which can be costly in terms of both lost production time and potential repairs.
Safety Concerns: A worn-out chain poses safety risks to both equipment and personnel. Sudden chain failure could lead to accidents, injuries, or damage to surrounding equipment.
Higher Maintenance Costs: Neglecting chain wear can lead to a ripple effect of damage, causing not only the chain to fail but also impacting sprockets and other interconnected components. This translates to higher maintenance and replacement costs.
