General description
B+S type TRP and STEFA type 6CC are seals with completely
rubber covered Outer Diameter. This type of seal is
designed for pressures up to 0.5 MPa. In order to avoid a
“pop-out“ of the seal, we suggest to fit an axial retainer
(e.g. circlip, shoulder, etc.) The additional dust lip protects
the main sealing lip against dust and other fine solid
contaminants and therefore this type is recommended for
use in polluted environments. To achieve a long lifetime a
suitable lubricant between the two sealing lips should be
applied.
Advantages
- Good static sealing
- Compensation of different thermal expansion
- Reduced risk of fretting corrosion
- Up to 0.5 MPa pressure at moderate peripheral speed
- Low lip and shaft wear at low pressure run
- Effective protection against air side contaminants
- No need of back-up ring
Application examples
- Transmission systems (e.g. gearboxes)
- Pumps
- Hydraulic motors
- Machinery industry
Technical data
Pressure: up to 0.5 MPa
Temperature: -40 °C to +200 °C
(depending on material)
Speed:
Media:
up to 10 m/s
(depending on pressure and material)
mineral and synthetic lubricants
(CLP, HLP, APGL etc.)
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.
