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.
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.
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 slewing ring bearings with external gear
– VSI slewing ring bearings with the internal gear
– VSU slewing ring bearings without gear
