Radial Factor of Roller Contact Bearing given Race Rotation Factor

Go Radial Factor = (Equivalent dynamic load on bearing-(Thrust Factor for Bearing*Axial or thrust load acting on bearing))/(Race-rotation factor*Radial load acting on bearing)

Radial Load on Bearing given Race Rotation Factor

Go Radial load acting on bearing = (Equivalent dynamic load on bearing-(Thrust Factor for Bearing*Axial or thrust load acting on bearing))/(Radial Factor*Race-rotation factor)

Race Rotation Factor of Roller Contact Bearing

Go Race-rotation factor = (Equivalent dynamic load on bearing-(Thrust Factor for Bearing*Axial or thrust load acting on bearing))/(Radial Factor*Radial load acting on bearing)

Axial Thrust Load on Bearing given Race Rotation Factor

Go Axial or thrust load acting on bearing = (Equivalent dynamic load on bearing-(Radial Factor*Race-rotation factor*Radial load acting on bearing))/Thrust Factor for Bearing

Reliability of Complete Bearing System Formula

Reliability of Bearing System = Reliability of Bearing^Number of Bearings
R_s = R^N_b

What is a rolling contact bearing?

The term rolling contact bearings refers to the wide variety of bearings that use spherical balls or some other type of roller between the stationary and the moving elements. The most common type of bearing supports a rotating shaft, resisting purely radial loads or a combination of radial and axial (thrust) loads.
