Loads

Minimum load For additional information → Requisite minimum load	P_m = 0,01 C₀ Oil lubricated bearings: n/n_r ≤ 0,3 → P_m = 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: F_ap = 0,003 B d
Equivalent dynamic bearing load For additional information → Equivalent dynamic bearing load, P	F_a/F_r ≤ e → P = F_r + Y₁ F_a F_a/F_r > e → P = 0,67 F_r + Y₂ F_a Perform calculations
Equivalent static bearing load For additional information → Equivalent static load	P₀ = F_r + Y₀ F_a
