Needle Roller / Axial Ball Bearings NX20 Z 20x30x28 mm
Item number:
NX20-Z
Item features:
The combined needle roller bearing NX20-Z combines the benefits of a radial needle roller bearing with those of a full complement axial deep groove ball bearing and carries high radial loads and axial loads in one direction. It has no inner ring and requires therefore a particularly small radial installation space.
