High speed bearing of dental drill

Drill bearing It is a special bearing for dental handpiece. Shanghai Yuwei Bearing Co., Ltd The inner and outer rings of the drill bearing are made of refined stainless steel (9gr18); the balls are made of refined stainless steel (9gr18) or non-metallic superhard ceramics (Si3N4) with good wear resistance; the cages are made of polyimide or 80-120 pieces of phenolic resin sandwich rubber wood with high strength, low wear resistance and self-lubricating properties. The drill bearing is under 200-250kpa air pressure, The rotational speed can reach 350000-400000 rpm. Under normal service conditions, the service life of the drill bearing is more than 6 months.

The manufacturing precision of special bearing for high-speed dental mobile phone conforms to P4 tolerance of national standard GB / t307.1-94, which can be applied to different models of dental mobile phones in the world. For example, NSK in China and the West in Japan, W & H in Austria, bein air, Lars in Switzerland, KaVo, Faro in Germany, Beijing, Shanghai, northwest factory in the United States, Midwest, Adec, Yoshida, Siemens, star in the United States and other brands of high-speed dental drill turbine phones.

Drill bearing dimensions

Here are some basic information about drill bearings:

Brief introduction of drill bearing

With the development of medical technology, there are more designs for high-speed dental drill phones, but each design includes turbine, nose, coupling, and a drill bit. Driven by the turbine, the maximum speed of the bit can reach 450000 rpm.

 Drill bearing

The bit is the most important part of the drill. It is short and highly durable and can withstand very high speeds and the resulting high temperatures. The air turbine engine is sandwiched between two high-speed bearings and is wrapped in the drill bit to drive the bit directly through a series of drive shafts and gears. The key factor of high speed of drill bearing. Therefore, bearing accuracy, material, structure, rolling element, groove and cage material have a direct impact on the performance of dental drill bearing. Dental drill manufacturers and dental partners have an important supply of dental bearings.

Characteristics of drill bearing

Yuwei bearing is a leading manufacturer of high precision drill bearings. Our drill bearings have the following characteristics:

1. Real 450000 RPM high speed; special P4 / ABEC 7 precision; stainless steel (440 C) ferrule and ceramic (silicon nitride) ball; composite fiber reinforced phenolic retainer

If the drill bit can reach a very high speed, it can reduce the pain of patients in the treatment of teeth. 450000 rpm is internationally recognized as the highest speed that dental drill bearings can reach. There are few bearing manufacturers in the world that can meet this requirement, and lieli bearing is one of them. In order to produce the highest quality dental drill bearings, we have done a lot of tests and experiments, and now we have a stable production and bearing quality.

2. Precision of special P4 / ABEC 7 bearing:

In addition to 450000 speed, the ability to achieve P4 / ABEC7 bearing accuracy is another important factor to measure the ability of a bearing manufacturer. Although many factories mark P4 / ABEC7 accuracy on their own products, once using these bearings, it is easy to find that they do not have these accuracy levels, and most of these fake bearings only have ABEC3 accuracy grade. This is also the reason why the prices of some drill bearings are particularly low.

But these low-quality drill bearings will greatly damage the drill phone and equipment. According to statistics, more than 60% of the bearing market is flooded by fake bearings. Due to the limitation of materials and production process, the rigidity of these low-end bearings can not meet the national standards, which will eventually shorten the service life of the instrument and cause damage to other components. The difference between different ABEC accuracy levels may also lead to assembly difficulties and even scrapping of the entire equipment. Lieli bearing has become the leading micro bearing manufacturer in China, and has achieved P4 / ABEC7 level, and even some models can reach P2 / ABEC9.

3. Stainless steel (440C) ferrule and ceramic (silicon nitride) ball material:

The ring of these drill bearings can only be made of stainless steel (9gr18), and the rolling element is made of silicon nitride ceramic ball. The selection of high-quality raw materials significantly improves the durability and speed of the bearing, thus ensuring the overall performance of the drill bearing.

4. Composite fiber reinforced phenolic retainer

Yuwei bearing 100% focus on every impact bearing product quality details. The composite fiber reinforced phenolic retainer has been subjected to rigorous and complex chemical treatment. It ensures that the bearing can run for about 18 months at the maximum speed of 450000, and the whole rotating process is low noise and low vibration. Because the chemical oil is immersed in the retainer, these drill bearings have good self-lubricating function.


Maintenance of high speed turbine drill bearing

 Drill bearing

1. Clean external surface of the handpiece.

2. Insert the drill chuck.

3. Clear the inside of the phone head as follows:

A. Spray for 1 to 2 seconds.

B. Wipe the debris and debris in the machine head with a paper towel.

C. Repeat the above two steps until it is completely clean.

D. Dry the surface of the machine head.

E. Repeat until the surface is completely dry.

4. Disinfect the handpiece according to the instructions of the dental drill handset manufacturer.

5. Cool the machine head to room temperature.

6. Drop 2 drops of lubricating oil into the driving air pipe.

7. Wipe off the excess lubricating oil.

8. Wipe the outer surface.

9. Now the dental drill mobile phone can be used.

In order to ensure the high-speed performance, a certain axial preload should be added when the drill bearing is installed into the machine head. Users should carefully operate, install and maintain the ball and raceway carefully to avoid damage to the ball and raceway. The pollution and improper lubrication of the bearing will directly affect the performance index and service life. ours Drill bearing Products also include: dental bearings, dental bearings, dental handpiece bearings, dental bearings, dental drill phone Palin, high-speed bearings, KaVo mobile phone bearings, wh mobile phone bearings, NSK dental drill bearings.
