Axial needle roller and cage assemblies AXK correspond to DIN 5 405-2. They comprise plastic or metal axial cages with integral needle rollers and have a very low axial section height.

The cage assemblies can support high axial forces in one direction. Radial loads must be supported by separate means.

Axial needle roller and cage assemblies require hardened and ground running surfaces as a raceway.

Axial bearing washers AS are punched, through hardened, polished and suitable for use as shaft or housing locating washers. They correspond to DIN 5 405-3 and are suitable for use with axial needle roller and cage assemblies AXK.

These washers are suitable for use where the adjacent machine part is unhardened but is sufficiently rigid and geometrically accurate.

Axial needle roller bearings AXW are units comprising axial needle roller and cage assemblies AXK and axial bearing washers with centring spigot. They can be combined with drawn cup needle roller bearings and machined needle roller bearings.

The running surface for the needle roller and cage assembly must be hardened and ground.

Needle roller and cage assemblies and needle roller bearings with plastic cage are suitable for operating temperatures from –20 °C to +120 °C.

Case assemblies with a plastic cage have the suffix TV.

Suffixes for available designs: see table.

Axial needle roller bearings are available in a special range with two raceways in various sizes. Please contact us for further information.
