How to maintain the optimal state of high-speed dental handpiece bearings？

1. Two high-speed dental handpieces are used alternately.

 During the use of dental handpiece, the bearings have been rotating at high speeds. At this time, the balls in the bearings are constantly circulating to exert pressure on the inner and outer rings of the bearing. If it is used for a long time, it will cause "mechanical fatigue" of the bearing. And then directly affect the life of the bearing. Dentist usually use a treatment table with standard configuration, which is equipped with two high-speed dental handpiece. If the dentist uses one handpiece for a period of time (one treatment is appropriate) and replaces it with another handpiece, that is two handpiece used alternately, this can greatly alleviate the impact of "fatigue" on the life of dental handpiece bearings. Thereby prolonging the service life of the dental handpiece to a great extent. According to statistics, almost 60% of dental handpiece bearings are damaged due to "fatigue".

2. Bearing cleaning and lubrication is also a very important link.

Cleaning is to prevent foreign matter from entering the bearing and increase the friction between the ball and the inner and outer rings of the bearing. This is a process of replacing the water and foreign matter in the air pipe of the handpiece with detergent and lubricating oil. Lubrication is to reduce the friction between the ball and the inner and outer rings of the bearing, so that the dental handpiece can rotate at high speed. In terms of lubrication, we need to use professional dental handpiece lubricants. Dental handpiece lubricating oil is liquid. When the handpiece bearing rotates at high speed, a large amount of oil will be lost and the bearing will be in a "dry" state quickly. Therefore, it is necessary to fill the handpiece with oil before each use, so that keep the dental handpiece bearing in a lubricated state in time.

3. Adjust the corresponding air pressure according to different brands and models of dental handpiece.

 SENDA brand optical fiber high speed handpiece with quick connection that is generally use the air pressure is 0.25-0.3Mpa, and the air pressure used by ordinary high speed handpiece is 0.22-0.25Mpa.
