| | | Bearing selection, on an axial load basis, must be considered independently from the radial load.
1. Calculate the axial loads acting on the bearing.
2. Multiply each load by the appropriate dynamic factor fz
3. Combine these loads to determine the effective axial load Pa
4. Select a bearing having a Ca value greater than the product of Pa x fdn, d.n is the product of the shaft size in mm and the speed in r.p.m. To determine fdn use the velocity graph below.
| | These ratings are for constant loads with oil or extra pressure greases. If greases without extra pressure additives are applied then the catalogue rating must be decreased by 50%. In instances where bearings operate at over 50% of their catalogue speed rating and over 50% of their axial load ratings (Ca) then recessed shafts should be considered. Please contact our Technical Services Department.
