General description
The B+S type TRG and STEFA type BD are special metal
cased radial oil seals without spring energised sealing lip.
These types are not recommended for use in heavy
polluted environments. As the static sealing between
housing and metallic shell is limited, low viscosity media
can “creep“. Better performance can be achieved with
Epoxy based resin O.D. coating. This special treatment is on
request.
Advantages
- Good radial stiffness
- Good fitting stability avoiding pop-out of the seal
- Low friction and low heat generation
- Extremely compact design
- Low radial force provides a low brake-out torque
Technical data
Pressure: without pressure
Temperature:
Speed:
Media:
-40°C to +200°C

mineral and synthetic base greases
B+S/STEFA have carried out several thousand compatibility
tests. Please ask for details.
Important Note:
The above data are maximum values and cannot
be used at the same time, e. g. the maximum
operating speed depends on material type,
pressure and temperature.
- Suitable for scraper applications
Application examples
- Roller bearings
- Tooling fixtures (e.g. drilling machines)
- Sealing against viscous media (e.g. grease)
- Supplementary excluders (shaft ends)
