BS Roller Chains

BS roller chains, while having the same fundamental components as other roller chains, are defined by their specific dimensions and tolerances. BS chains generally have a larger pin diameter relative to the pitch compared to ASA chains. The roller diameter and other dimensions also vary, meaning a BS chain will not properly engage with an ASA sprocket.

BS Roller Chain Features & Brands

Made from high quality steel, many of our BS Roller Chains are built to be durable, wear resistant and versatile.

The precision-engineered rollers and bushings of BS chains are designed to minimise friction as the chain engages with the sprocket teeth. This smooth operation reduces power loss, which contributes to the overall efficiency of the power transmission system.

Challenge

Challenge is known for its durable and long-lasting chains, particularly within their X-Series. Their chains often feature:

  • Spin-riveted pins for superior lateral strength and even load distribution.
  • High-grade alloy steels throughout the construction to increase wear resistance.
  • Seamless rollers made from chromium molybdenum steel to prevent deformation and premature failure.
  • A proprietary pre-lubricant for enhanced performance and extended service life.

Dunlop

Dunlop is a well-established brand offering a comprehensive range of roller chains, including both British Standard (BS) and American Standard (ANSI) types. Key features often include:

  • High tensile strength and reliable performance, meeting or exceeding minimum international standards.
  • A range of options, including simplex, duplex, and triplex (single, double, and triple-strand) chains for various load requirements.
  • A focus on dimensional accuracy, which ensures proper meshing with sprockets and long-term reliability.

Renold

Renold is a globally recognised manufacturer with a reputation for precision-engineered chains. Their products are known for their exceptional fatigue resistance and wear life. Noteworthy features include:

  • Solid bushings and rollers for superior wear resistance.
  • Ball-drifted plate holes and shot peening, which are processes that reduce fatigue failure and increase the chain’s working life.
  • High-waisted side plates for better stress distribution and an increased breaking load.
  • End-softened pins that make the chain easier to disassemble for maintenance.

Tsubaki

Tsubaki is an innovative and premium brand that is often a leader in technology and specialised chain solutions. Their chains are known for:

  • High fatigue strength and tensile strength, often exceeding standard specifications.
  • A focus on lube-free technology in some of their product lines, which is ideal for applications where lubrication is difficult or not possible.
  • Specialised chains designed for specific environments, such as corrosion-resistant chains or chains for high-temperature applications.

BS Roller Chains Applications

BS roller chains are a versatile component used across a broad spectrum of industries, including:

  • Industrial Machinery: Powering equipment in manufacturing, processing, and assembly lines.
  • Conveyor Systems: Driving conveyor belts in material handling, logistics, and warehousing.
  • Agricultural Equipment: Used on various farm machines for tasks like crop processing and power delivery.
  • Automotive: Employed in older automobiles and some modern applications for engine timing systems.
