Zexus range of roller chains, the SBR and Neo-SBR have outperformed competitors for the last 20 years and now one of the markets most respected brands just got 30% better.  

• Maximum allowable load increased by 30%. Highest published M.A.L of any of the premium quality chain brands
• SBR-Prime offers long service life for chain and selection with M.A.L equal to a chain size lower. This is achieved by compressive residual stress zoning. They have identifed the areas of the chain that
• benefit from better tolerances and made improvements. 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
