Plastic bearing POM 693 Glass Ball 3X8X3 mm

SKU: 42030803360

Plastic bearings are commonly used in application where it requires exposure to water, chemical, or electrical (insulated) environment. This type of bearing does not require any oil lubrication as it self-lubricates. This type of bearing is also low noise and has longer life span.

This 3 x 8 x 3 mm (POM 693) bearing is a plastic bearing with Glass ball . The POM 693 inner diameter is 3 mm, the POM 693 outer diameter is 8 mm, the POM 693 width is 3 mm.


Here are some characteristics of PP and POM plastic bearing that might give you an idea of which one is more suitable for your application.

Polyoxymethylene (POM)
- higher strength, greater hardness
- higher thermal stability
- wear resistance
- suitable to be in contact with food type applications
- resistant to weak acid and weak oxidant
- anti-rust

Polypropylene (PP)
- good corrosion resistance
- high mechanical strength
- high wear resistance
- strong anti-adhesion ability
- great electrical insulation
- good resistance to high radiation
- anti-rust

Example applications:
Mechanical, electrical, hospital equipment, food machinery, furniture and building materials

This bearing is Open, it does not have seal on neither side.
