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. L_e - length of 1 part. Z_e - number of neadels in 1 row of 1 part.
