Oil seals close off the space between stationary and moving components in the mechanical equipment. It saves the lubricant from escaping through the equipment and ensures smooth operation of the machine.


What should you take into account when selecting an oil seal? Different types of oil seals and various types of materials are available, each designed for specific uses. It is also important to select the right size of oil seal for the best results. For this reason, selecting the right oil seal requires adequate understanding of the application in which it will be used.
Note: For seal type codes, see Table 2.

ERIKS also supplies the types GR and GRST. These are virtually identical to the types R and RST, except in this case the metal inner ring is also completely encased in rubber. ERIKS uses FKM rubber here as standard, so these seals are ideal for use in acidic environments.


These oil seals are created from a low-temperature tolerant compound. Benefits include:

Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
