BRS Slewing Ring Bearings VSA|VSI|VSU Slewing Rings

VSA|VSI|VSU slewing bearings belong to INA standard series 20/25 four-point contact ball bearings. They are suitable for moderate to heavy loads, but cannot be subjected to loads as high as crossed roller bearings of same size.

VSA-VSI-VSU slewing rings feature:

1. Support axial, radial, and tilting moment loads.

2. Normal clearance, suitable for light to medium-duty arrangements that require lower accuracy.

3. Easy installation, with mounting holes on both inner and outer ring.

Application

VSA-VSI-VSU slewing ring bearings are suitable for applications with lower requirements for accuracy and rigidity of the bearing arrangements, for example, cranes, turntables, rotary tables, metalworking machines, construction machinery,  etc.

VSA-VSI-VSU slewing rings model:

– VSA slewing ring bearings with external gear

– VSI slewing ring bearings with the internal gear

– VSU slewing ring bearings without gear
