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.
Profile identifiers refer to the FST technical catalogue. Supply configuration and documentation are confirmed for the specific enquiry.
