Plastic bearing POM 689 Glass Ball 9X17X5 mm

SKU: 42091705360

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 9 x 17 x 5 mm (POM 689) bearing is a plastic bearing with Glass ball . The POM 689 inner diameter is 9 mm, the POM 689 outer diameter is 17 mm, the POM 689 width is 5 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
