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.
