Application parameters

For the standard materials combination

Temperature  -40°C to +100°C                                                                                           
Pressure max. 0.5 MPa (optional 1 MPa)
Shaft speed max. 12 m/s
Media Mineral oil based lubricants, synthetic lubricants

When synthetic lubricants are used for which there is no empirical experience, test the compatibility in the laboratory or - better even - in practical trials. The operating temperature should not exceed 80°C.

The different permitted maximum values should always be seen in connection with all application parameters. The total load on the seal is the combination of individu al values.
