The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating, at an ambient temperature of 20 to 30 °C (70 to 85 °F). Therefore, only the sliding frictional moment and the frictional moment of seals, if applied, are taken into consideration. M start = M sl + M seal.
