Data for the correct selection.

Selection parameterWhat to specify
DimensionsShaft/rod or bore diameter d/D; groove diameter; width H; tolerances
Material and compoundCompound code, hardness, reinforcements and any required approvals. Check the individual profile document.
MediumFluid type, concentration, additives and cleaning agents.
Service conditionsMinimum/maximum temperature, pressure and peaks; sliding speed or rotation; duty cycle.
InstallationGroove drawing, surface finish, clearances, pressure direction and assembly method.
Traceability and documentsSpecify 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.
