Linear guides
Linear guides form the basis of a linear bearing. They usually take the form of a metal strip with fixing holes and a raceway for the rolling elements of the bearing cages. The raceway can be flat or profiled. The main task of linear guides is to transfer pressure from the machine parts to which they are bolted to the rolling elements and to provide the rolling elements with the best possible conditions for correct operation.
N/O
General information
Like M/V-type linear guides, the N/O-type is also designed for high-load applications. The bearing assembly consists of a pair of N and O linear guides with 90° raceways. Angular needle-, roller-, or ball bearing cages operate within the raceways.
N/O-type linear guides are manufactured from tool steel grade 1.2842 with a hardness of 58–62 HRC. A stainless version is available, made from 1.4034 steel with a minimum hardness of 54 HRC.
