*)   - 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 and 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
**) - Standard value for 100 mm long cage.
       - Formula for calculation of the oscillations damping force for the effective length of a bearing cage  RSw=RS*(Lk-2e+t)/100
