Dental Handpiece Ceramic ABEC-7 Bearing SR144TLKZN 3.175x6.35x2.38
Product Description
The Dentist Dental bearing is a special mobile phone bearing.
Our production of dental drill bearing inner and outer rings through refining stainless steel (9Gr18) materials; ball by refining stainless steel (9Gr18) or non-metal super hard Si3N4 materials with good wear resistance; holder has the advantages of high strength, low friction with.
And a self lubrication performance of polyimide or 80 ~ 120 phenolic clamp cloth bakelite material, dental drill bearing in 200 ~250Kpa air pressure, speed up to 350000 ~ 400000rPm. Under normal condition, dental bearing working life for more than 1 year. High speed dental cell phone bearing manufacturing accuracy in line with the national standard P4 level GB/T307.1-94 tolerance,can be applied to different types of dentists in the world. With the development of medical technology, now the high-speed dental drill mobile phone with more design, but each kind of design include turbine, head, couplings, and a bit. In the turbine driven by the drill bit can reach maximum speed of 450 thousand revolutions per minute. The drill bit is the most important part of the dental drill. It is short and highly durable, able to withstand very high RPM as well as the resulting high temperature. The air turbine engine is sandwiched between 2 high speed bearings and is wrapped in a bit, which is driven directly by a series of drive shafts and gears. The key factor to achieve high speed dental drill bearing.
