CHAINS IN THE A+ RANGE

We can now offer one of the most advanced chains in the world, SBR – Solid Bush Roller. This chain is composed of entirely solid components, unlike traditional chains that have rolled or pressed components. Therefore, this superior quality SBR chain offers high tensile strength, less elongation due to wear and longer service life in comparison with standard roller chain. The Japanese Sugiyama Chain Co. Ltd. manufactures chains since 1946 and is the only company in the world producing Silver SBR.
Why choose SBR? 

SBR – SOLID BUSH ROLLER
Both bushes and rollers are produced from solid pieces of steel without heating. The components do not expand and the surface remains unchanged. By cold drawing the steel, the molecular structure remains intact and the original fatigue strength is retained. The design of the SBR chain reduces friction and heat generation that entails a more even wear and minimal elongation of the chain, it retains the lubrication and requires minimum maintenance. The components are produced from high quality materials, link plate holes are double punched to improve component fit and increase fatigue.

Our chains are also continuously pre-loaded following final assembly.

THE TECHNOLOGY BEHIND SBR 
Our seamless SBR bushes are produced from a single piece that, consequently, significantly improves the service life of the chain in comparison with standard chain.

SHOT PEENING
During the manufacturing process, the components are fortified by shot peening to increase fatigue strength, giving the chain a significantly longer service life.

PUNCHING
The double punching process eliminates the taper in the hole and offers parallel sides for improved bearing surface between pin and hole. This process also increases the fatigue strength.

PRE-LOADING
The chain is continuously pre-loaded following final assembly to reduce chain elongation.

OUR ROLLER CHAIN ASSORTMENT

We can provide most types of roller chain – SLR self-lube, AP aqua proof, DC dual capacity, SSS stainless, SLR AP self-lube aqua proof, X-ring maintenance free, Hollow pin chain, chain fitted with attachments as well as various special chains adapted to any design according to your needs.
