Alumina ceramic ball bearing

Properties of Alumina Ceramic Bearing

1. Alumina ceramic bearings exhibit excellent corrosion resistance, allowing them to function normally under harsh conditions with corrosive media.

 

2. The ball density of alumina ceramic bearings is lower than that of steel, resulting in a lighter weight. Consequently, the centrifugal effect on the outer ring during rotation can be reduced by over 40%, meeting the requirements for higher rotational speeds.

 

3. Alumina ceramic has a low coefficient of thermal expansion, allowing the bearing to operate effectively in environments with significant temperature fluctuations, given a certain bearing clearance.

 

4. Alumina ceramic possesses a higher modulus of elasticity than steel, making it less prone to deformation under stress and thereby enhancing the bearing's load-carrying capacity.

Usage Instructions

 
1. Bearing Selection
Alumina ceramic bearings are precision components that require appropriate selection based on shaft size, tolerance, and load to avoid improper fits or overloading.
 
2. Bearing Installation
When installing alumina ceramic bearings, equal pressure should be applied around the circumference of the housing bore to insert the bearing. It is strictly prohibited to strike the bearing end face directly with heavy tools such as hammers to prevent bearing damage.
 
3. Matching of bearing and shaft
The fit selection of alumina ceramic bearing must be selected according to the load direction and load features. For rotating load and indefinite load, the ring should adopt a static fit, and for static load, the combination of excessive fit and dynamic fit can be adopted.
 
4. Bearing Lubrication
Alumina ceramic bearings inherently possess some lubricity. However, to further enhance lubrication and ensure longevity during high-speed operation, a suitable amount of lubricating oil or grease can be added.
 
5. Bearing maintenance
Regularly check the vibration and noise of alumina bearing, the temperature of bearing operation and the state of lubricating oil, according to the use of the environment and operating conditions of regular cleaning and maintenance, timely clean off the debris on the bearing.
