The occurrence of high friction immediately during installation or during operation at elevated temperatures is eliminated by extending the installation site. This can be done with re-adjustable housings by installing the required number of washers. It is recommended that this extension be 2.5% of the groove length.
After a long period of operation and possible wear, the service life and good sealing effect can be extended by tightening the seal. This is done by removing a number of washers. It is recommended that this shortening is 7.5% of the groove length. |
