Test specification of plastic coated bearings

Plastic coated bearings generally refer to bearings with a layer of plastic wrapped around the outside. The plastic material is generally nylon PA, polyoxymethylene POM and engineering plastics polypropylene, pp. The outer plastic has a certain hardness, impact resistance, wear resistance and a certain self-lubricating property.

Classification of engineering plastic bearings:

1. According to bearing materials: POM/PA precision plastic bearings, PP/PE/UPE acid and alkali resistant plastic bearings, PEEK/PI high temperature resistant plastic bearings, PTFE/PVDF corrosion resistant plastic bearings, plastic spherical bearings, plastic linear bearings, slewing bearings, fiber winding bearings.

2. According to bearing types: deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, double row angular contact ball bearings, plane thrust ball bearings, outer spherical ball bearings, various engineering plastic bearing seats, outer spherical ball bearings, angular contact balls, deep groove ball bearings.

3. According to bearing accuracy: P0, P6, P5

4. According to bearing size: miniature bearings, small bearings, small and medium bearings, medium and large bearings, large bearings (bearings with a nominal outer diameter range of 3-430mm).

5. According to processing technology: German design, cloud production, cost-effective full plastic bearings, German design, German production, full plastic bearings that can be customized according to customer special requirements.

Plastic-coated bearings are a newly emerging industry in China recently. They are widely used in mechanical equipment, industrial assembly lines, furniture and hardware accessories. According to different application purposes, the appearance of plastic-coated bearings can be made into different shapes, and can be made into pulleys such as V-grooves.
