Plastic bearing POM 639 Glass Ball 9X30X10 mm

SKU: 42093010360

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 30 x 10 mm (POM 639) bearing is a plastic bearing with Glass ball . The POM 639 inner diameter is 9 mm, the POM 639 outer diameter is 30 mm, the POM 639 width is 10 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
