Maximum allowable load increased by 30%. Highest published M.A.L of any of the 
premium quality chain
brands.
SBR-Prime offers longer 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.
