Figure 2-1 XLplus and VLplus heavy-duty bearing systems
The multi-stage helical gearbox sizes 89-169 can be supplied with an XLplus or VLplus heavy-
duty bearing system.
The parallel-shaft gearbox and the helical gearbox sizes 89-169 can be supplied with a VLplus
heavy-duty bearing system.
With an upstream locating bearing, the bearing system is suitable for high external forces.
The absorbed radial and axial loads are transmitted to the machine via the flange.
The bearings are lubricated independently of the frame size. Initial greasing has already been
carried out. The relubrication is made with the provided grease nipple.
Options for the VLplus heavy-duty bearing system:
An automatic regreasing device ② can be supplied as option. The automatic regreasing
device ② can be installed at any position and can be used underwater.
A dry-well version with oil sight glass ④ or oil sensor ⑤ can be supplied as option. The dry-
well version offers increased protection against oil leaks when the output shaft points down.
The flange captures any escaping gear oil for leakages at the oil chamber. The escaping oil is
signaled optically with an oil sight glass ④ or electronically by an oil sensor ⑤. If the oil
sensor ⑤ is deployed in ATEX version gearboxes, the sensor must be operated with a
disconnector approved for ATEX.
