  • How to tell when a slewing ring bearing needs to be ...

    The play, or clearance, in a slewing ring bearing is another important indicator of a problem. A new bearing is assembled with a specific amount of clearance to compensate for slight out-of-flatness encountered in a mounting structure. This clearance can increase dramatically due to wear.

  • Questions & Answers

    How much clearance is allowed on my slewing ring? That all depends on the type of slewing ring, the application and initial clearance. To determine the maximum allowed clearance of a slewing ring it is absolutely necessary that the initial clearance after mounting the new or reconditioned slewing ring is measured and documented. After that, to check if the slewing ring is still under the ...
