Phenolic resin idler pulleys with simple yet innovative design display superior performance and durability. The pulleys are made of special phenol resin for higher durability than conventional nylon based material. The alternate heat resistance bearing contribute to light weight and cost reduction. The expanded flaking resistance helps to countermeasure technology during conditions of vibration and very high temperatures (180 degrees Celsius). Introduction of special raceway material, retainers, seals and heat treatment delivers superior heat-proof performance.
The rolling bearings with ceramic balls offer an enhanced turbocharger performance. The rocker arms include low-friction roller follower. The contact surface is flexibly adjusted for minimal friction. The split type needle roller and cage assemblies prove suitable for big ends of motorcycle connecting rods and severe lubrication conditions e.g. in two-cycle engines etc to ensure minimization of output loss. The sealed bearings are suitable for motorcycle high-pressure applications and high temperature and pressure inside crankshaft cases
