Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings. Drawn cup roller clutches with plain bearings: During operation, the product of the actual speed n and radial load Fr must not exceed the value stated for the limiting load (Fr * n) max. The operating limits are determined by the stated limiting speeds and the permissible radial load.
