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.
Angular double-row plastic bearing cages with bearing needles
Made of abrasion resistant plastic.
Working temperature up to do 120°C.
Cage sides are symmetrically bent at the right angle towards each other.
Applicable areas include also linear guides of the types "M" and "V", "RM", "RV", "N" and "O"

*) - 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.
- Cage i composwed of parts. Le - length of 1 part. Ze - number of neadels in 1 row of 1 part.
