Data for the correct selection.
| Selection parameter | What to specify |
|---|---|
| Dimensions | Shaft/rod or bore diameter d/D; groove diameter; width H; tolerances |
| Material and compound | Compound code, hardness, reinforcements and any required approvals. Check the individual profile document. |
| Medium | Fluid type, concentration, additives and cleaning agents. |
| Service conditions | Minimum/maximum temperature, pressure and peaks; sliding speed or rotation; duty cycle. |
| Installation | Groove drawing, surface finish, clearances, pressure direction and assembly method. |
| Traceability and documents | Specify the required compound, conformity declarations and batch documentation in the enquiry. |
Temperature, pressure and speed limits depend on the exact compound, profile and installation. Do not combine maximum ratings from different conditions or extend one profile’s ratings to the whole family.
