*)  - Load capacity for 1 ball with the thrust force "F" in accordance to the drawing.
     - C - dynamic load capacity, C0 - static load capacity
     - 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
