Why use Engineering Plastic Bearings and Bushes?

Three common types of bearings and bushes used in engineering and industrial applications are illustrated here.

Top 5 reasons why Plastic Bearings or Bushes are used in engineering and industrial are: 

  1. Eliminating lubricants.
  2. They tolerate dirty and dusty environments.
  3. Lower friction than bronze.
  4. Reduced wear on the counter-face compared to bronze.
  5. Longer service life vs bronze

Other reasons include light weight, chemical resistance, reduced cost, vibration dampening & insulation (electrical and thermal).

Design & Selection Criteria

 

Dotmar has qualified engineers that can help design bearings and select the most appropriate material.

The following information is required:

 

  • Load
  • Speed
  • Duration of operation
  • Size
  • Conditions – Abrasive, dry or wet etc

 

Other requirements that can be designed for are:

 

  • Food contact
  • Metal detectable, as well as blue Visual detectable and X-Ray detectable
  • FRAS – Fire retardant and Anti-static
  • Chemical resistance
  • Lubrication
