xirodur® B180 | The all-rounder

The widest range of plastic ball bearing applications is covered by xirodur® B180. This material is regarded as an all-rounder. In addition to its high wear resistance, the material offers good chemical resistance and medium temperature resistance. The mechanical properties are a good combination of certain hardness as well as elasticity. This variant is supplied in combination with a PA cage.

Typical applications:

Automotive

Packaging

Roller bearing

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.
