Needle 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 range of needle bearings is extensive and, in addition to customized designs, it comprises the following types: Needle bearings Needle roller and cage assemblies Drawn cup needle bearings Alignment needle bearings Needle bearing inner rings Needle rollers Needle Roller Bearings Series Item NO.
