Dental drill bearing information

This class bearing special bearings for Dental dentist phone, the inner and outer rings of refining stainless steel (9Cr18Mo) material the ball refined stainless steel (AISI440C) or a non-metallic super-hard ceramic material (SI3N4), has good wear resistance cagethe imported the TORLON or high-strength low-friction and self-lubricating properties of polyimide material or 80 to 120 phenolic Textolite material, bearing 200 ~ 250Kpa air pressure, the speed of up to 300 000 to 400 000 rpm. Under normal conditions of use, bearing the working life of more than 6 months.The high-speed dentists dedicated phone bearing manufacturing precision meets the P4 level national standards GB/T307.1-2005 requirements can be applied to different models at home and abroad dentists phone high-speed grinder.

Dental drill bearing material

We use steel balls imported from Japan ASK, the accuracy reached G3 level. (Foreign customers more commonly used ceramic ball.) High-speed bearings in key parts - retainer, made according to the different requirements of the world's top engineering plastics or other proprietary material eliminated abandoned domestic manufacturers used polyimide amine and a phenolic resin (Bakelite). (Polyimide biggest problem is that the cage in the case of high-temperature high-pressure, high-speed, cause the cage fall apart, thereby affecting the normal work of the dental drill.) Torlon PAI (polyamide - imide resin imported directly from the United States ), high temperature, abrasion resistance, low friction, high strength, and excellent performance. By more than excellent parts consisting of high-speed miniature bearings with high-speed (up to 35 - 45 000 rev / min), low-noise, low-friction torque, long life and other advantages. Stability is our commitment to quality is the bearing stability
