Needle rollerssizes

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.
