Plain Bearings (Bushings)

Sliding / Plain Bearings (Bushings)

Major Use Cases:
Because plastic plain / sliding bearings (bushings) are highly resistant to friction and abrasion, as well as being self-lubricating, they are basically perfect for conditions where oil or grease can be major issues.

They are most suitable for devices that cannot function well with oil, in parts that get wet, and in areas where grease hardens at high temperatures.

Moreover, because plastic bearings are lighter and more elastic than metallic bearings, they are resistant to shocks and fretting (refer to glossary), and they can be used in diverse shapes, not only as bushings, but also as liners or blocks.

These bearings are used in numerous ways in various fields, including automatic machinery; textile machines; transportation and conveyance machines; chemical and food-processing machines; as well as machines related to ensuring environmentally friendly conditions (e.g., water and garbage treatment).

Plain bearings (bushings) are most suitable under the following conditions:

  • Operating in dry environments
  • Operating in irregularly wet / damp environments
  • Operating in water continuously / regularly
  • Operating in seawater
  • Operating in steam
  • Operating in chemicals
  • Operating in high temperatures
