Roller Bearing Selection Calculator

Calculate bearing life, equivalent dynamic load, and minimum required load rating for roller bearings.

Radial force on the bearing.
N
Axial (thrust) force on the bearing.
N
Bearing rotational speed.
rpm
Desired bearing life.
hours
Depends on bearing type. Deep groove: 0.56, Angular: 0.43.
Depends on contact angle. Deep groove: 1.63, Angular: 1.0.
