Product Description

Custom POM Ceramic Ball Bearing for Precision Motion Applications

SUNTRON custom POM ceramic ball bearings combine engineering plastic performance with ceramic ball technology to deliver smooth, reliable and contamination-resistant rotation.

The bearing is manufactured with CNC machined POM inner and outer rings, zirconia ceramic balls, and a customized integrated dust protection structure. This design reduces friction, improves corrosion resistance and provides stable performance in demanding industrial environments.

Compared with traditional metal bearings, POM ceramic bearings offer advantages including lightweight construction, lower operating noise, excellent chemical resistance and suitability for applications where metal contamination must be minimized.

Each bearing can be customized according to your drawings, dimensions and application requirements.
