Product introduction Main parameter Details Picture

Cylindrical roller backing bearings are available with two or three rows of rollers, in full roller bearing (without cage) or cage bearing form, either with or without integral retaining edges or retaining rings. The advantages of bearings without retaining edges are their particularly simple geometry and high radial load capacity.
Cylindrical roller backing bearings without flanged edges or retaining rings cannot carry any axial loads.Therefore it is necessary to place bronze or plastic thrust washers between the outer ring and the side of the supporting saddle. Backing bearings with a retaining edge (or retaining ring) do not require thrust washers because the design of these bearings allows them to withstand the simultaneous action of radial and axial forces. Cylindrical roller bearings are commonly used as backing bearings.
