intruduction of handpiece bearings j* This kind of bearing is specially used in dental handpiece, inner and outer rings are made of refining stainless steel(9crl8mo), the ball is made of refined stainless steel (AISI440C/9Ci 18Mo) or lion-metallic hard ceramics(Si3N4)with good wear resistance; cage uses material with a high strength ,low friction resistance and self-lubricating properties of Trolon or 80 ~ 120phenolic cloth bakelite material, the bearing 200~250kPa air pressure, the speed of up to 350000 ~450000rmp.Under normal use conditions,the bearing operating life can be more than 6 months . Production precision of High Speed Dental phone bearings can reach to national standards GB/T307.1-2005 P4 level requirements,which can be applied to different types of dentists phones abroad .Our Company's high-speed dental bearings can also be high-speed mobile grinding machine.

jfmmps.fiis Introduction of dental drill bearing products The speed of high-speed dental drill ball bearings for high-speed dental drill mobile phones can reach 400,000 rpm, which can be exchanged with the bearings in dental drill mobile phones produced in Japan, Germany and Britain. Under normal service conditions, the clinical service life of bearings shall not be less than six monthSo High-speed dental drill ball bearing is a kind of precision miniature bearing, which should be carefully operated and carefully maintained during installation and use, otherwise it will directly affect the performance...

1. Bearing materials are very important for its accuracy, performance and service life. The material of bearing ring of high-speed turbine dental drill mobile phone should be special corrosion-resistant stainless steel, the ball material should be Si3N4 ceramic ball with small thermal expansion coefficient, and the cage material should be poly-imide TORLON with compression resistance, impact resistance and 2. Strict processing technology of bearings is the key to the success of products. According to the structural characteristics and technical requirements of high-speed dental drill bearings,...
