Seals
Depending on the application, our rolling bearings can be equipped with different sealing systems. Seals are necessary in the protection of bearings when compressed with dust, dirt, water spray or other media and guarantee their good function over the entire service life. Both, the type of seal and the selection of materials whose construction for long-lasting protection against invading media and leakage are essential.
The following sealing systems are common:
- Z =
- single-sided sheet metal cover plate gap seals
- ZZ =
- as above, on both sides
- RSR =
- single-sided, polished rubber seal
- 2RSR =
- as above, on both sides
- RZ =
- single-sided, non-contact rubber seal
- 2RZ =
- as above, on both sides
Under extremely demanding operations, our sealing systems can be supplemented by additional labyrinth sealing elements which greatly enhance the sealing effect. These labyrinth seals impede the path dirt particles and moisture take to get into the bearings.
In addition to our standard sealing systems we can offer a variety of proven special sealing systems. We'll gladly advise when it comes to selecting a suitable sealing system for your individual application.
