​​​​​​Technical information on Axial needle roller bearings

Axial needle roller bearings are particularly suitable where:

• high axial forces occur in one direction but no radial loads are present (the bearings may only be subjected to axial load)
• 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
• higher speeds occur in addition to high axial loads
• the bearing arrangement must have very high axial rigidity
• the axial space available is extremely small
• the bearing parts can or must be mounted separately
• the bearing arrangement is not configured but, for cost reasons, ready‑to-fit standard bearings are to be used
