xiros® deep groove ball bearing xirodur® F182, electrostatically dissipative
xirodur® F182 | electrostatically dissipative
Compared with the xirodur® F180 material, F182 is classified in the conductive category according to DIN EN 61340-5-1 due to its even lower surface resistance. This means that uncontrolled discharges do not stand a chance. In addition to its electrostatic discharge capacity, this material is particularly durable.
Typical areas of application:
- Packaging industry
- Food industry
- Computer and semiconductor industry
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
