The importance of slewing ring bearing maintenance in
The use of a slewing ring bearing provides yet another benefit: its shaftless design eliminates the need for a spindle or kingpost. The center of the bearing remains open to allow passage of various hydraulic and control components. Since the bearing is so critical, careful maintenance is necessary. More than 96% of slewing ring bearing
- The Latest in Slewing Ring Bearing Technology
In contrast, sliding slewing ring bearings use self-lubriing, low-friction polymer sliding elements in place of balls. Where roller bearings require constant lubriion and regular maintenance, sliding slewing ring bearings are a ‘fit-and-forget’ solution, as they do not require any additional lubriion or scheduled maintenance.
