The V-Ring is normally stretched and mounted directly on the shaft, where it is positioned by the inherent tension of the rubber body. It rotates with the shaft and seals axially against a stationary counterface, at right angles to the shaft.
Roto Glyd Ring is used to seal rods, shafts, axles, bores, rotary leadthroughs, journals, swivels etc. with rotary or oscillating movement. The seal is double-acting and can be exposed to pressure from one, or from both sides.
