| Recommended Dimensions (mm) |
| Minimum nominal inner diameter d≥22 mm.Depending on the application, the geometry of the guide element shall be adapted to the application type (refer to the outline description - sealed housing).Since the uncut version is meaningless for assembly, rotating application conditions should be avoided.The standard version with a cutting gap of > 0 does not allow a supporting function.To achieve the supporting function, a cutting gap of s = 0 and spiral grooves are provided. The value of the cutting gap depends on the material and temperature. For detailed information, please refer to the personal data description. |
