Equivalent Dynamic Load-Tapered Roller Bearings

The equivalent dynamic load of taper roller bearings can be calculated as the following Table 1.

Table 1 

Bearing Structure

Equivalent Dynamic Load

Single row taper roller bearing

Fa/Fr ≤e P = Fr

Fa/Fr >e P = 0.4Fr + YFa

Annex axial component of forces S = Fr/2Y

Single row taper roller bearing

of paired mounting

(Arranged face to face or back to back)

Fa/Fr ≤e P = Fr + Y1Fa

Fa/Fr >e P = 0. 67Fr + Y2Fa

Double-row or four-row taper

roller bearing

Fa/Fr ≤e P = Fr + Y1Fa

Fa/Fr >e P = 0.67Fr+Y2Fa
