1).This split needle roller and cage assemblies are ready-to-mount, self-contained, bearing arrangement components. They enable bearing arrangements to be produced which have high load carrying capacity and stiffness and require a minimum of radial space if the shaft and housing bore can serve as raceways and have the same hardness and surface finish as bearing rings. If the raceways are made with increased accuracy, bearing arrangements with high running accuracy can be achieved.
2).The needle Roller and cage assemblies are available in single row and double row designs. They are characterised by
3).The needle rollers are slightly relieved towards their ends. The modified line contact thus achieved between rollers and raceways means that damaging edge stresses are avoided.
