General description<br />
The design of mainly used GAMMA seal TBP/RB is based on<br />
many years of experience in such applications. The total<br />
axial force of the sealing lip is given by elastomer<br />
pre-stretching together w<strong>it</strong>h lip deformation force which<br />
depends on the elastic<strong>it</strong>y of the rubber material, geometry<br />
of the sealing lip and assembly pos<strong>it</strong>ioning against the<br />
counter-face. The metal shell is protecting the seal from<br />
solids and contributes to exclude other pollution media by<br />
centrifugation, allowing a good drainage after immersion<br />
in liquids.<br />
Advantages<br />
- Good dynamic sealing<br />
- Very good protection against solid pollution particles<br />
- Modern lip design provides low axial forces<br />
(low power loss)<br />
- Small f<strong>it</strong>ting width<br />
- No supplementary retention’s needed<br />
Application examples<br />
- Transmission systems (e.g. gearboxes)<br />
