Linear Bearings | N/O

Linear bearings type N/O are suitable to support and guide high loads and moments very accurate. Due to the close arranged needle rollers they provide extremely high rigidity, high linear motion accuracy and a compact size.


N/O Linear bearings

Structure and Features
A typical installation consists of 2 pairs of linear bearings; each pair is made up of (2) guideways, 1, N-type (female) and 1, O-type (male), through-hardened and precision ground, with one needle roller cage in-between. The guideways are made to very high tolerances and matched together as a set. Mixing components from different sets may affect the accuracy.

 

Guideways are equipped with countersunk-boredattachment holes, according to a standard configuration.


Threaded holes in ends for fixing endstops and wipers.


For the attachment, special screws type GD can be ordered separately.
