Product Features


● The bearing specially designed for the automotive steering system. The designation is with the advantages of combining high elastic material and high wear resistance material CSB-EPB7. This perfect design provides the solution of ensuring both elastic resistance duration and wear resistance could be both guranteed.


● High elastic feature and stable sliding resistance;


● Outstanding wearing resistance;?


Structure Design


CSB-RPM Steering Rack Bearing is made from the combination of elastic material and wear resistance material. The individually designed slot in 120 degrees around the diameter provides easy assembly of the bearings. The 3 pilot blocks near the surface end of the bearing hold the bearing from the axial movement during the operation. The oil deposits in the bearing layer hold the lubricants during the initial assembly for a better lubricating feature and provide good wear resistance of the bearing.


Material Design


The main material of the bearing is the elastic and fatigue resistance polymer which provide long lasting stable sliding resistance of the bearing. The bearing layer of the ID is made of CSB-EPB7 material which prevents the loss of elastic feature due to the


quick wear of the bearing ID.


Assembly Design


CSB-RPM5 Bearing is designed for direct press fit installation. The interference of OD ensures the bearing to be tightly seated in the housing without clap ring installed. Recommended grease：CALTEX Multifak EP2 or ONELUBER MONO.2
