General description<br />
The B+S type TRG and STEFA type BD are special metal<br />
cased radial oil seals w<strong>it</strong>hout spring energised sealing lip.<br />
These types are not recommended for use in heavy<br />
polluted environments. As the static sealing between<br />
housing and metallic shell is lim<strong>it</strong>ed, low viscos<strong>it</strong>y media<br />
can “creep“. Better performance can be achieved w<strong>it</strong>h<br />
Epoxy based resin O.D. coating. This special treatment is on<br />
request.<br />
Advantages<br />
- Good radial stiffness<br />
- Good f<strong>it</strong>ting stabil<strong>it</strong>y avoiding pop-out of the seal<br />
- Low friction and low heat generation<br />
- Extremely compact design<br />
- Low radial force provides a low brake-out torque<br />

Application examples<br />
- Roller bearings<br />
- Tooling fixtures (e.g. drilling machines)<br />
- Sealing against viscous media (e.g. grease)<br />
- Supplementary excluders (shaft ends)<br />
- Axle King Pin seals<br />
