General description<br />
The B+S type TRK and STEFA type CD are specially designed<br />
radial oil seals reinforced w<strong>it</strong>h a metal insert but w<strong>it</strong>hout<br />
spring energised sealing lip. The B+S type TRK has a wavy<br />
rubber covered outer diameter. STEFA CD type are<br />
available w<strong>it</strong>h flat rubber covered O.D. These types are<br />
not recommended for use in heavy polluted environments.<br />
Advantages<br />
- Good static sealing and thermal expansion compensation<br />
- Low friction and low heat generation<br />
- Extremely compact design<br />
- Low radial force provides a low brake-out torque<br />
- Su<strong>it</strong>able for scraper applications<br />
Application examples<br />
- Roller bearings<br />
