The linear bearing cage is an essential component of a linear rolling bearing built with the use of linear guides. The main task of the bearing cage is to hold the rolling elements inside the bearing on the guide's raceways in the correct operating position.
Segmets design enables to combine them in a bearing cage of various lengths
Working temperature up to 105°C
Applicable to automatics, mechatronics, optomechanics.

*) - Load capacity for 1 roller with the thrust force "Fn" in accordance with the drawing.
- C - dynamic load capacity, C0 - static load capacity
- The load capacity is calculated for guides with 90º V-profile (where bearing roller touches the guidway track with its total length Lw) with hardness of 60 +/- 2 HRC and surface roughness of Ra<0.4.
- Load capacity of bearing cages is calculated on the basis of number of bearing rollers mounted in the cage
- Length tolerance LK +0/-t
