General description<br />
B+S type TRA and STEFA type CB are seals w<strong>it</strong>h completely<br />
rubber covered outer diameter. Two different O.D design<br />
are available : Flat rubber sheath as well as wavy.<br />
This type is not recommended for use in heavy polluted<br />
environments.<br />
Advantages<br />
- Good static sealing<br />
- Compensation of different thermal expansion<br />
