First-class flexibility

Machined PEEK bearing cages are used where non-metallics are preferred and for highly demanding conditions with high speeds, chemical attack or high temperatures.  We manufacture bearings cages in a number of PEEK grades depending on application requirements.  

The exceptional properties of PEEK include: 

  • Superior combination of strength and flexibility 
  • High operating temperature range 
  • High chemical and wear resistance 
  • Good processability 

Bearing Cage Temperature Range

Due to these outstanding features, PEEK cages are used for some ball and cylindrical roller bearings, like hybrid and/or high-precision bearings.  

The material does not show signs of ageing by temperature and oil additives up to +200 °C. However, the maximum temperature for high-speed use is limited to +150 °C as this is the softening temperature of the polymer. 

Victrex PEEK Bearing Cage

We currently manufacture large filled VICTREX® PEEK bearing cages for one of the UK’s largest producers. 

We can also coat existing bearing cages with VICTREX® PEEK to enhance their properties for a range of applications.

We can manufacture large filled PEEK bearing cages and also coat existing cages in PEEK to improve their temperature resistance.
