Needle roller bearings have needle rollers as rolling elements. In terms of rolling bearing technology, cylindrical rolling elements are classified as needle rollers if the rolling element diameter is ≦6 mm and the ratio of the rolling element diameter to the rolling element length is Dw/lw ＜ 1:3.

Due to the small diameter of the rolling elements, all needle roller bearings have the common feature of a low radial section height. Due to the line contact, they are particularly suitable for bearing arrangements with high radial load carrying capacity and rigidity in a restricted radial design envelope.

Radial needle roller bearings can only be used as non-locating bearings. The defined axial displacement value in the case of bearings with inner rings allows axial motion between the shaft and housing. Where necessary, wider inner rings are available for larger displacement values.

Product Description

Features

The bearings can support high to very high radial forces.

The bearings are used when the load carrying capacity or accuracy of drawn cup needle roller bearings with open ends is no longer sufficient and the high load capacity of cylindrical roller bearings is not yet required.

The bearings can only support radial loads and, as a result, are highly suitable for use as non-locating bearings (they permit axial displacement of the shaft relative to the housing in the bearing).

The bearings permit high speeds in spite of line contact

The bearings compensate misalignments between the shaft and housing (aligning needle roller bearings).

The bearings require only a very small radial design envelope, particularly if the bearing arrangement is designed without an inner ring.

The bearings are available in numerous sizes and designs.

The bearings result in particularly compact, cost-effective and economical bearing arrangements.
