Profile S is wide and tapered, which provides a very firm hold on the shaft. The rings are available for shaft diameters from 5 to 199 mm. The Trelleborg V-ring® is an all-rubber seal for rotary shafts, rotating with the shaft and sealing axially against the stationary counterface. Its light lip pressure generates low friction. It can also be used as a secondary seal to protect primary seals that do not perform well in hostile environments.
