Besides the oil seals, the shaft-hub connection and the lubricant used, the key factors in determining the service life of an industrial gear unit are the rolling bearings, the loads placed on them and the gearing’s load capacity for reliably transferring the torque.

These loads primarily result from the torques and the radial and axial forces that affect the output shaft of the gear unit during operation and are consequently transferred to the bearings. Other factors that influence the bearing service life are the type of gear oil, the oil level in the gear unit and the application’s ambient conditions.
