Special size - Type VA..S

External seal for grease only

 

 

 

 

At  low  peripheralspeeds  and  very  good  –  if possible,  lapped  –  mating surfaces, it can also be used with liquids.
This seal can be employed in either a stationery or rotating manner.
For use with liquids, the maximum permissible speed must be reduced to 1/3 of the figure indicated in the table.
By increasing the spring force, it is possible to raise the medium pressure by up to 50%, however this can result in greater friction and heat-up, and consequently in faster wear.
