Less ware and higher fatigue strength
40% longer servicelife
30% less elongation

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 resistance is retained. Thanks to the design of the SBR chain, friction and heat generation are reduced. This entails more even wear and minimal elongation of the chain. The chains retain the lubrication and require a minimum of maintenance. When producing the components, only materials of the highest quality are used. The surface of the chains is shot peened to “de-stress” the material and provide greater resistance to fatigue. All of our roller chains are naturally preloaded.

Chains in the A+ range
We can now offer one of the most advanced chains in the world: SBR – Solid Bush Roller. This patented chain comprises entirely solid components, unlike traditional chains that have rolled or pressed components. The SBR chain therefore offers unsurpassed quality and service life. Japan’s Sugiyama Chain Co. Ltd., which has been manufacturing chains since 1946, is the only company in the world to produce Silver SBR.

Shot peening
The chain components are shot peened to achieve improved fatigue strength, giving the chain a significantly longer service life.

Double punched plate holes
The double punching process eliminates the taper in the hole. The sides of the hole are parallel, proving an improved bearing surface between pin and hole. This process also increases the fatigue strength.
