PEEK BEARING CAGES

In many applications PEEK has replaced metals such as brass or aluminium to reduce both the weight and cost of the part. PEEKs resistance to aging and the absorption of humidity makes it ideal for applications such as process pumps handling liquefied gases and hydraulic fluids. Machined bearing cages made from PEEK have high chemical resistance to lubricants and additives.

Characteristics include:

  • High operating temperature and able to withstand high speeds
  • High chemical and wear resistance
  • Good processability
  • Superior combination of strength of flexibility
  • Good tribological properties

To improve these attributes in applications requiring high speed and high temperature or those with a need for chemical resistance, PEEK can be reinforced (filled) with glass or carbon fibre.

PEEK is resistant to ammonia and sour gas and is an excellent alternative cage material to brass in applications such as Screw compressors, other applications include:

  • Helicopter gearboxes
  • Traction motors
  • Construction equipment
  • Automotive
  • Formula One
  • Wind turbines
  • Roller bearings
