Gear unit mounting for hollow shaft gear units

Due to the rigid connection between the machine shaft and the hollow shaft of the gear unit, constraining forces can be imposed on the output shaft bearing. This damages the output shaft bearing and promotes the formation of friction corrosion in the connection between the machine shaft and the hollow shaft of the gear unit.

Possible damage to property.

• For machine shafts without their own bearing or with only one bearing point, the gear unit is designed with foot or flange mounting and used as a bearing point. Make sure that the bearing is very well aligned coaxially to the existing bearing point.
• If the machine shaft has at least two bearing points, the gear unit should be connected merely to the machine shaft and supported with a torque arm. To prevent overdetermination of the bearing, gear units with foot or flange mounting must be avoided.
