FAQ

What are the key mounting and lubrication requirements for the VSU250955 slewing ring?

Correct mounting is critical. The mounting structure must be flat and rigid to prevent distortion. Use grade 10.9 bolts torqued to the manufacturer's specification in a star pattern. For lubrication, a high-pressure EP (Extreme Pressure) grease suitable for rolling bearings should be used, applied through the grease nipples to purge old grease and ensure all raceways and gears are protected.

The VSU250955 features external gear teeth. According to the Schaeffler datasheet, the gear module is 10. This specification is crucial for matching the bearing with the corresponding drive pinion.

Yes, as a four-point contact bearing, the VSU250955 is specifically designed to accommodate a combination of loads. It can handle significant axial and radial forces as well as tilting moments from a single bearing position, making it ideal for applications like cranes and excavators.
