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.
Flat single-row bearing cages with bearing needles
Manufactured from profiles of light metals - aluminium (Al), brass (Ms) or steel (F)
High precision and strength at low deadweight (aluminium)
Destined for heavy-duty working conditions at high loads and accelerations
Working temperature up to 150°C
Applicable to linear flat guides

*) - Load capacity for the theoretical length of the cage of 100 mm with the thrust force "F" in accordance to the drawing.
- 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
