Needle roller/axial ball bearings

Needle axial bearings combine a radial needle bearing with an axial ball bearing. This allows them to not only withstand high radial forces, but also one-sided axial forces. Needle axial bearings are characterized by their lack of an inner ring, making them particularly space-saving. However, they require that the raceway on the shaft be hardened and ground. If this is not the case and if the shaft cannot be hardened and ground, we offer inner rings (IR) that can be ordered separately.

These bearings are available in two versions: with a full ball set (NX) or a cage-guided rolling element set (NKX). The NX design allows for very compact bearings with small shaft center distances. A steel sheet protective cap attached to the radial part encloses the shaft disc of the axial bearing and holds the axial part together. The NKX design is not self-retaining, so the individual bearing parts can be mounted separately. The NKX..-Z design, on the other hand, is self-retaining, as it is equipped with a steel sheet protective cap that holds the axial part together. This protective cap is without lubrication holes and firmly connected to the housing disc of the radial part.

For applications where one-sided axial forces from different directions need to be absorbed, two bearings should be placed against each other.
