OIL FILM BEARINGS

Primary shaft oil seals for oil film bearings. The BBS^® oil seals are available in both DF and MX style to fit every customers’ requirement.

Used in steel mill: back-up rolls (hot and cold rolling mills). The BBS^® oil seals can be supplied together with the corresponding Water Seal, or with specific V-Rings (secondary seal).

Our competitors mostrly use a resin to fix the garter spring. After some time  the resin may dry-out and break and the spring can go into the bearing, causing damages. Sometimes it could even happen during the assembling.

The •FP• and ATS spring is completely vulcanized into the sealing lip so to avoid such a problem.

Furthermore •FP• and ATS have developed a special HNBR compound with a better resistance to temperature and less friction and abrasion problems.

Secondary seal for oil film bearings installed as a protection from the cooling media. Available also with a finger spring vulcanized in the sealing lip.

The finger spring has the function to constantly maintain the lip preloaded, even after the rubber loses its flexibility with time. The finger spring also enables the sealing lip to better copy the axial movement of the shaft.

The Water Seal is available also without finger spring.

Also available with its corresponding BBS® seal type (primary seal)
