Defective ball bearing
New ball bearing
Lubrication of ball bearing
Insufficient lubrication of the ball bearings causes signs of excessive wear and tear possibly leading to defects. To prevent any secondary damage, have defective ball bearings replaced quickly.
Signs indicative of defective ball bearings include:
- Loud running noise
- Uneven run
- Handpiece jams completely
- Strong increase in temperature
Even missing lubrication once, in particular after internal cleaning, can lead to early damage to the ball bearing.
Prevent damage from dropping
Check the handpiece by eye for any changes during the reprocessing process in order to protect both the handpiece and the patient.
Consequential damage, such as jamming of ball bearings, can cause thermal damage to the ball bearings and thus rapid failure.
Procedure for detecting damage from dropping the handpiece:
- Visual inspection for external damage reveals deformation
- Functional test reveals excessive running noise and/or excessive heating
If you are not sure about damage from dropping a handpiece, please contact your KaVo Service Centre to prevent possible secondary damage.
