Needle Roller / Axial Cylindrical Roller Bearings NKXR20 Z 20x30x30 mm
Item number:
NKXR20-Z
Item features:
The combined needle roller bearing NKXR20-Z combines the benefits of a radial needle roller bearing with those of an axial cylindrical roller bearing and carries high radial loads and high axial loads in one direction. It has no inner ring and requires therefore a particularly small radial installation space. The main dimensions correspond to DIN 5429 (DIN = German industrial norm).

Features
- combination of a radial needle roller bearing and an axial cylindrical roller bearing
- suitable for high radial loads and relatively high axial loads in one direction
- space-saving due to low radial section height
- with end cap, for grease lubrication
- condition for the use is a hardened and ground shaft; if the shaft is not usable as raceway, a combination with an inner ring is possible
- with circumferential groove and lubrication holes in the outer ring
- material: chrome steel (100Cr6), plastic (axial cage)
