They have identifed the areas of the chain that benefit from better tolerances and made improvements.
Benefits of SBR-Prime Chain:
- Maximum allowable load increased by 30%. Highest published M.A.L of any of the premium quality chain brands.
- Triple zone hardness of all components high energy mechanical process - three layers of hardness instead of one as different parts of the pin and bush respond better to different hardness.
- Stainless steel blast treatment for pin and bush combined with special lubrication offers corrosion resistance to these components.
