![]() As a result, it can transmit higher forces, has greater rigidity and allows smaller rolling element diameters under the same load. In contrast to the ball, the roller has a larger contact area perpendicular to the roller axis. ![]() Ready-to-fit bearing units with very small axial spaceĪxial needle roller bearings are part of the group of axial roller bearings. Such bearings are used, due to their low axial section height, in applications such as automotive manual gearshift transmissions. bearings with centring spigot (prefix AXW) ➤ Figure and ➤ Figure.įurthermore, Schaeffler supplies axial needle roller bearings by agreement for specific applications, for example with tabs to prevent rotation.complete axial needle roller bearings (comprising a needle roller and cage assembly and axial bearing washers) ➤ Figure.T = axial section height of axial deep groove ball bearingĪxial needle roller bearings are available as: the bearing arrangement is not configured but, for cost reasons, ready‑to-fit standard bearings are to be used.Īxial needle roller bearing and axial deep groove ball bearing – comparison of load carrying capacity and design envelope.the bearing parts can or must be mounted separately.the axial space available is extremely small ➤ Figure.the bearing arrangement must have very high axial rigidity.higher speeds occur in addition to high axial loads.the load carrying capacity of comparable axial deep groove ball bearings is no longer adequate and the very high axial load carrying capacity of axial cylindrical roller bearings is not yet necessary ➤ Figure.high axial forces occur in one direction but no radial loads are present (the bearings may only be subjected to axial load ➤ section). ![]() Axial needle roller bearings are particularly suitable where:
