Needle Roller / Axial Ball Bearings NX7 TN 7x14x18 mm
Item number:
NX7-TN
Item features:
The combined needle roller bearing NX7-TN 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.

Features
- combination of a radial needle roller bearing and a full complement axial deep groove ball bearing
- suitable for high radial loads and axial loads in one direction
- space-saving due to low radial section height
- without end cap, for oil 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)
- temperature resistance: from approx. –20 °C up to +120 °C
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
