*) - 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  |
