Rolling Path Skewing

Rolling Path Skewing

Condition Cause Solution
  • Rolling element contact path on raceway surface strays or skews.
  • Deformation or tilt of bearing ring due to poor accuracy of shaft or housing
  • Poor rigidity of shaft or housing
  • Deflection of shaft due to excessive clearance
  1. Improvement in machining accuracy of shaft and housing
  2. Improvement in rigidity of shaft and housing
  3. Employment of adequate clearance
