Loads
Minimum load
For additional information → Requisite minimum load | Pm = 0,01 C0
Oil lubricated bearings: n/nr ≤ 0,3 → Pm = 0,003 C0 ![]() Perform calculations |
Axial load carrying capacity | SKF spherical roller bearings are able to accommodate axial loads and even accommodate purely axial loads.
Bearings correctly mounted on an adapter sleeve on plain shafts without fixed abutment: Fap = 0,003 B d |
Equivalent dynamic bearing load
For additional information → Equivalent dynamic bearing load, P | Fa/Fr ≤ e → P = Fr + Y1 Fa
Fa/Fr > e → P = 0,67 Fr + Y2 Fa Perform calculations |
Equivalent static bearing load
For additional information → Equivalent static load | P0 = Fr + Y0 Fa
