32018X Tapered roller bearings

The equivalent dynamic load of tapered roller bearings is calculated according to different structures as follows:

Dynamic equivalent load of shaft-borne structure

Single row tapered roller bearing Fa/Fr≤e P = Fr

Fa/Fr > e P = 0.4Fr + YFa

Additional axial component S = Fr/2Y

Single row tapered roller bearings mounted in pairs Fa/Fr≤e P = Fr + Y1Fa

(Face to face or back-to-back configuration) Fa/Fr > e P = 0. 67Fr + Y2Fa

Double or four row tapered roller bearings Fa/Fr ≤e P = Fr + Y1Fa

Fa/Fr > e P = 0.67Fr+Y2Fa

Equivalent static load

The equivalent static load of tapered roller bearings is calculated according to different structures as follows:

Dynamic equivalent load of shaft bearing structure

Single-row tapered roller bearings generally P0 = 0.5Fr+YoFa

P0 < Fr P0 = Fr

Single-row tapered roller bearings mounted in pairs are generally P0 = Fr + YoFa

(Configured face to face or back-to-back) P0 < Fr P0 = Fr

Double row or four row tapered roller bearings generally P0 = Fr + YoFa

P0 < Fr P0 = Fr
