What impact will it have on the dental handpiece if it use ultra-high air pressure for a long time?


1. When the high air pressure is used, the noise of the mobile phone is loud, and the doctor's long-term work will cause auditory fatigue; it may even lead to poor patient experience.

2. The life of the bearing will be affected. The bearing has a limit speed. Exceeding the specified air pressure will cause the bearing to wear faster and the cage to break

3. Comparing the speed of normal air pressure operation and the limit speed of ultra-high pressure operation, the working efficiency is not much different; the limit speed will increase the wear of the bearing and affect the service life. In the long run, it will increase the operating cost of clinic equipment.

For example: the normal speed range of dental handpiece bearings:

At the normal air pressure of 0.25-0.3Mpa, the speed of the dental handpiece reaches 360,000-410,000 rpm/min.

Even if the air pressure is opened to 0.4-0.5Mpa, the speed of the dental handpiece will not exceed 410,000 rpm/min.
