  • Ring material: xirodur® A500
  • Cage material: PEEK
  • Ball material: PAI


PEEK PAI bearing is the specialist for high chemical and temperature resistance. In combination with the PEEK cage, this material covers applications with continuous operating temperatures from -100 °C to +150 °C and is highly resistant to strong acids in particular. In addition, the individual parts of this material combination have FDA conformity. Due to its medium wear resistance as well as higher price, this material should also be chosen only for such applications.

Typical areas of application:

Food industry (system cleaning with chemicals)
Electroplating
Semiconductor industry
Vacuum applications
Autoclave applications



Tolerances and measuring system:

The tolerances for inner and outer diameters depend on the size. These are often approx. ±0.05 mm to the nominal dimension. The bearing rings are usually injection molded and naturally exhibit a certain ovality. For this reason, the caliper gauge is used to measure 90° to the injection point (if present) over the entire width of the bearing. The dimensions and tolerances are designed to meet an easy press fit by hand when using a H7 mounting as well as shaft h6. Additional axial securing by means of a circlip (shaft) and snap ring (housing) is recommended to prevent axial displacement.

Mounting recommendation:


PEEK PAI ball



1. mounting (tolerance H7)

2. front side (balls visible)

3. rear side (cage visible)

4. press in ball bearing with front side first

5. mount shaft (tolerance h6) with chamfer

6. an axial safety device must be provided
