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:
- Eliminating lubricants.
- They tolerate dirty and dusty environments.
- Lower friction than bronze.
- Reduced wear on the counter-face compared to bronze.
- 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
