*)  - 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.
