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 with 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 which 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 internal gear
