Description Technical Specs
 
20B Roller Chain is a British Standard metric chain designed in accordance with ISO R606 and DIN dimensional standards. It has a 1-1/4" pitch (center of one pin to the center of the next) and is manufactured out of a high-grade carbon steel for strength and long-term performance. What separates our 20B from the others out there is a solid roller design, wide-waste link-plates, factory pre-loading, precision shot-peened and heat-treated parts, and high-quality factory supplied grease on the chain. These features all contribute and work together within your chain to create a tough and reliable product ready for just about any industrial application out there.

Corrosion Resistant 20B Roller Chain

Some applications require an anti-corrosive 20B metric chain due to corrosive factors or wash-down duty requirements.
Stainless Steel 20B Roller Chain:

Made from a high-quality 304-grade stainless steel 20BSS chain is the most anti-corrosive 20B chain available, for more information on stainless steel chains go to our stainless steel roller chain page.
Nickel Plated 20B Roller Chain:

A nickel plated chain is made with a special plating on each component to create an anti-corrosive barrier on the chain.
Coated 20 B Roller Chain:

The best all around anti-corrosive chain option is to use the coated version. It is coated with a proprietary compound that outlasts nickel plating in almost every application 5+ times.

We also stock and supply a range of 20B chain sprockets, the below charts shows our standard sprocket sizes. If you don't see the sprocket you need or currently have please contact us, we also supply custom and specialty 20B sprockets within an industry leading turn around time.
