General description<br />
B+S type TRU is a seal w<strong>it</strong>h completely rubber covered<br />
outer diameter. This type of seal is designed w<strong>it</strong>h an<br />
extended metallic support of the diaphragm that allows<br />
pressures up to 0.5 MPa. In order to avoid a “pop-out“ of<br />
the seal, we suggest to f<strong>it</strong> an axial retainer (e.g. circlip,<br />
shoulder, etc.). The add<strong>it</strong>ional dust lip protects the main<br />
sealing lip against dust and other fine solid contaminants<br />
and therefore this type is recommended for use in polluted<br />
environments. To achieve a long lifetime a su<strong>it</strong>able<br />
lubricant between the two sealing lips should be applied.<br />
Application examples<br />
- Transmission systems (e.g. gearboxes)<br />
- Pumps<br />
- Hydraulic motors<br />
- Machinery industry<br />
Technical data<br />
Pressure: up to 0.5 MPa<br />
Advantages<br />
- Good static sealing<br />
- Compensation of different thermal expansion<br />

mineral and synthetic lubricants<br />
(CLP, HLP, APGL etc.)<br />
- Effective protection against air side contaminants<br />
- No need of back-up ring<br />
B+S/STEFA have carried out several thousand compatibil<strong>it</strong>y<br />
tests. Please ask for details.<br />
Important Note:<br />
The above data are maximum values and cannot<br />
be used at the same time, e. g. the maximum<br />
operating speed depends on material type,<br />
pressure and temperature.<br />
