Damage to Reteiners

Damage to Reteiners

Condition
  • Breaking of retainer
  • Wear of pockets or guide
  • Loosening or breaking of rivet
Cause
  • Excessive moment load
  • High speed spinning or large fluctuation of speed
  • Poor lubrication
  • Trapping of foreign objects
  • Heavy vibration
  • Poor mounting (cocked bearing)
  • Excessive heat (plastic retainer in particular)
Solution
  1. Improvement in load conditions
  2. Improvement in lubrication system and lubricant
  3. Selection of optimum retainer
  4. Improvement in handling
  5. Study on rigidity of shaft and housing
