Fabric shaft seal for wind mills WGV

The radial seal type WGV is especially used for rotational sealing of shaft lead-throughs in wind mills, but is also deployed in heavy machine construction, transmission construction, shipbuilding and wind mills. It has particular advantages in any application where misalignments and vibrations can occur! The back of the seal is made of a fabric reinforced and high resistance elastomer, specifically modified for the exceptional requirements of wind mills. The highly flexible sealing lip is supported by a coil spring.

Versions:
WGV-A (standard)
WGV-C (with friction optimised sealing lip)
