WMX® Bearings - Wrapped Acetal Lined Bearings

WMX® Bearings

Our WMX range of wrapped acetal lined bearings is suitable for rotary and oscillating movement applications. They benefit from long re-lubrication intervals, no absorption of water, outstanding damping behaviours and have a low susceptibility to edge loading.

The WMX range is ideal for the automotive, machine building and agricultural industries and indeed any application where lubricant cannot be supplied continuously.

Just a few examples of where our WMX range is used are as follows:

  • Rear chassis hinges
  • Articulation joints
  • Spindles of drills
  • Gearboxes & clutches
  • Grinding and milling machines


  • Our wrapped acetal lined bearings have a high wear resistance and low friction even with very small quantities of lubricant
  • The surface carries a pattern of circular indents which should be filled with grease on assembly
  • Low carbon steel gives exceptionally high load carrying capacity and excellent heat dissipation

Our WMX range of wrapped acetal bearings can hugely reduce maintenance costs on projects large and small and are stocked in metric plain, imperial plain, metric washers. Imperial washers, metric strip and imperial strip.
