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.

*) - Load capacity for 1 roller with the thrust force "F" in accordance to the drawing.
- C - dynamic load capacity, C0 - static load capacity
- The load capacity is calculated for guides with hardness of 60 +/- 2 HRC oand surface roughness of Ra<0.4.
- Load capacity of bearing cages is calculated on the basis of number of bearing needles mounted in the cage
- Length tolerance LK +0/-t
