Size Range:

From 3mm to 200mm,standard & non-standard

Type:

More than 350 types, including metric and inch deep groove ball bearing, self-aligning bearing, angular contact bearing, plain bearing, and spherical bearing. Open type, seal rings, shields can be provided.

Retainer: NYLON, PTFE, PEEK, steel, bronze, or full complements.

Non-standard bearing can be designed and provided upon requirement.

Features:

Compared with traditional metal bearing, full ceramic bearing is featured in following aspects:

1. Could be used at higher temperature. Ceramic maintains mechanical properties at high temperature, so full ceramic bearing can be used at elevated temperature.

2. Corrosion resistant. Full ceramic bearing are more suitable for chemical industry application.

3. More suitable for temperature-variation application. Because thermal expansion co-efficiency of ceramic are smaller than metal, so the change of clearance of full ceramic bearing is smaller than that of metal bearing.

4. More resistance to seizing due to smaller thermal expansion.

5. Could work under poor lubrication, because ceramics are self-lubrication. Full ceramic bearing could be used at high-vacuum environment.

6. Could be used as insulation bearing and can prevent Electrical Arcing because ceramics is not electrical conductor.

7. Could be used in magnetic environment because ceramics do not respond to magnetic forces.

 

Application:

Full ceramic bearing could be used in following industries: chemical, semi-conductor, valve & pump, food, electronic, medical, vacuum, refining, insulation, etc.

Note:

Full ceramic bearing is not suitable for heavy loading, impact loading and variable loading application.

CS CERAMIC High precision zirconia /ZrO2 ceramic ball

How a Ball is Made

 

Heading: In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.

 

Deflashing: The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates.

 

Soft Grinding: Similar to deflashing, except that a grinding stone is used to improve precision.

 

Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

 

Descaling: This step removes the residues and by-products from the heat-treating process.

 

Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ¡À.0001".

 

Lapping: Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade 10 - 48.

 

Finishing: Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.

 

Inspection: All products pass through at least two 100% inspection stages, using proprietary, automated inspection processes
