Needle Bearings

Needle roller bearings are roller bearings with cylindrical rollers which are thin and long in relation to their diameter. They are referred to as needle rollers. In spite of their low cross section the bearings have a high load carrying capacity and are thus extremely suitable for bearing arrangements where radial space is limited. The xtb-range of needle roller bearings is extensive and, in addition to customized designs, it comprises the following types: 1.
