xirodur® A500 | The specialist for high chemical and thermal resistance
The material xirodur® A500 is the specialist for high chemical and thermal resistance. In combination with the PEEK cage, this material covers applications with continuous service temperatures from -100 °C to +150 °C and is particularly resistant to strong acids. Ceramic balls made of zirconium oxide contribute to the high chemical and thermal resistance and ensure good wear resistance. This prevents bearing damage and subsequent costs.
Typical application areas:
- Semiconductor industry
- Chemical industry
Tech up:
- High chemical and thermal resistance of zirconium oxide
- Good wear resistance
- Large delivery program
Cost down:
- Avoid bearing damage and follow-up costs
Proof:
Sustainability:
- Environmentally friendly, as no additional lubricants are required
- igus supports the circular economy of plastics and invests in chemical recycling. More at: igus.eu/sustainability
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:
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
