Product of Ceramic Ball Bearing Specifications:

1)Dental Bearing of high precision level P4 (ABEC 7),
usable for various brands of high-speed dental turbine handpieces

2)Rotating speed 350,000-450,000 rpm under air pressure of 200-250Kpa

3)Working life for about six months under the regular operation

4)Very less vibration, Very less noise, Antirust, Corrosion resistant

5) High-temperature resistance for disinfection

6)The ceramic balls used in some Freerun dental bearings are more rigid, lighter, and wear-resistant than other bearing manufacturers’ stainless steel versions. Ceramic balls generate less centrifugal force at the high speeds dental handpieces operate, reducing wear on the bearing and producing wear particles, increasing lubricant life.

How to Use Ceramic Ball Bearing Correctly:

1). It is best that the interference fit between the bearing bore and turbine shaft is under    0.5um-1.5um. When putting the turbine shaft into the bearing bore, the pressure should be forced on the face of the inner ring to avoid damage to the rollway and balls.

2). After fitting the bearing into the turbine shaft, it should be instilled with special lubricant (ethanol must not be used).

3). After high steam sterilization, the high-speed dental handpiece should be jetted some lubricant into the air inlet before use so that the bearing can be used for a long time.

4). To keep operating stability, the preload spring stress of the bearing should be controlled under 1.2 +/- 0.2N.

Ceramic Ball Bearing Advantages:

One of the main advantages of ceramic bearings over bearings made of other materials is their high heat resistance. Ceramic bearings perform well at temperatures where other materials lose their mechanical properties. Ideal applications for these properties are: medical devices, chemical fiber instruments, and some aircraft components. In contrast, ceramic bearings can also provide rolling elements in low-temperature environments such as liquid oxygen.

The non-magnetic properties of ceramic bearings make them suitable for high magnetic field exposure applications. These include superconductor and semiconductor equipment, aircraft components, electron beam processes and other sensitive instruments.

Ceramic bearings are light weight and therefore help to reduce the overall weight of the product. Very effective applications for its lightweight are aerospace equipment and components, as well as motorcycle crankshafts. Reducing weight reduces the effects of vibration and stress in unbalanced applications and also increases speed and efficiency.

The hardness and stiffness of ceramic bearings are important to ensure that bearings can withstand loads. The hardness and stiffness of these bearings is greater than that of other bearing materials used. This means that ceramic bearings have higher wear resistance and therefore longer service life. This is essential for all different types of bearing applications; Including machine tool spindles, turbochargers, gas turbines, vacuum equipment and motors, etc.

Other Types of Sic Ceramic Ball Bearing:

Loose Ceramic Balls 1.5mm 2mm 3mm and other size SiC, this is a popular size that could be used in many Bicycle, or any application that uses this size 4mm.Ball is made of Ceramic SiC.
