Chain

Listing ID #3904930

• rockman chains are manufactured in state of the art facilities
• advanced automation machines ensure that the parts are assembled to the correct closed tolerances giving rockman chains a precise fitment in application
• chains are pre loaded at 50% minimum ultimate tensile strength which is specifically important for applications involving fixed center to center distance sprockets. This 50% proof loading eliminates initial elongation and increases chain fatigue resistance
• plate components are shot peened with control intensity and speed which allows the creation of compressive stress in the plates to avoid propagation of fatigue cracks
• rockman chains uses proprietary lubricants and vacuumed greasing processes designed to fully penetrate the bearing surfaces between pin and bushes ensuring higher wear resistance in automotive application

• solid bush drive chain
• 420 drive chain
• 428 drive chain
• 428 solid bush drive chain
• 428h drive chain
• 428h x ring drive chain
• 520 drive chain
• 520 o-ring drive chain
• 1595 o-ring drive chain
• 1595 w/o-ring drive chain

• starter cam chain
• 25h cam chain
• 25hs cam chain
• solid bush cam chain

all the o-ring chains have special grease vacuum sealed between pin and bushings preventing the penetration of dust from outside which can be used in very wide automobile application from low speed to high speed ensuring longest life of chain and its performance
