Needle and cage assemblies for crank pin bearing(KZK), the cage is quenched and tempered, so the assemblies has high strength and good abrasion resistance, the cage is designed to M type structrure and guided by the outer diameter. It has low weight and reliable function, because there are large guiding surface and good lubricating condition, the assemblies can be rotated under high speed. If there are special requirements, the surface of the cage can be plated with silver and copper.

 

 Needle and cage assemblies for piston bearing(KBK), the cage is an entity, and is hardened by quenching, so it has high strength and good abrasion resistance. Because the piston has large surface, the cage is guided by inner diameter.
