Transmissions

The requirements for transmission seals can be very different depending on the race series & the design & duty cycle requirements of the transmission.In the arduous conditions experienced in Rally Raid or World Rally Cars, the normal "oil containment" function of these seals is also dominated by the need for total exclusion of dirt, sand, mud & water. This means that a purpose-designed seal for these 4-Wheel Drive units can be significantly different from the lighter-duty seals normally found in catalogues.Many of these Rally transmissions also incorporate Active Differentials requiring rotary seals to seal at high pressures & to high RPM. Normally these applications would be met by PLS Seal assemblies incorporating SHP2 Seal elements within welded assemblies.
