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

Thrust factor of Bearing given Race Rotation Factor

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

Radial Factor of Roller Contact Bearing

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

Radial Load on Bearing

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

Axial Thrust Load on Bearing given Thrust Factor

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

Thrust factor of Bearing

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