V-ring Axial Counterface Seals

V-Ring is a solid rubber seal used on shafts to prevent dirt, moisture, and other unwanted material from entering an oil seal, housing, or any other desired area while simultaneously keeping lubricants in.

V-ring Axial Counterface Seals

Also names: Axial Counterface Seals, Water Seal, V-shaped End Face Seal, Grease or Dust Seal

A v-ring is an all rubber seal that mounts directly on a shaf and seals axially against either the housing or the metal case of a shaft seal. Once installed into an assembly, a v-ing will rotate with the shaft - unlike a shaft seal. Because v-rings rotate with the shaft they are often used in applications as slingers or deflectors. The centrifugal forces that are created by the rotating v-ring will deflect any contaminants -oil, dirt, sand, etc. - away from the sealing point of the application. Unlike a shaft seal, the v-ring is made out of 100% rubber which makes it completely elastic. Because they are elastic, v-rings can be installed into most applications without having to disassemble any components that may otherwise need to be removed for a standard seal to be installed. Also, each v-ring works on a range of shat diameters instead of one specific shaft diameter like a standard shaft seal.

Pinmo Sealing offers four standard v-ring styles. The four styles that are offered are the VA, VS, VE, and VL.

V seal profile

It works by stretching over the shaft to create a tight seal along the shaft while the flexible lip seals lightly against the counterface at a right angle to the shaft. The V-Ring works well on its own and excels when combined with rotary shaft seals to help extend the life of bearings, oil seals, and shafts. Gamma Seals provide the same function as V-Rings, but with the added protection of a metal case.

Benefits of V-rings

1) Simple – Little prep required when installing. Simply ensure the shaft is clean and try, apply a film of lubricant to the v-ring lip, and slide the v-ring down until the flexible lip contacts the counterface. The lip presses against counterface with little pressure and friction

2) Economical – Wide tolerances allow one v-ring to fit multiple shaft sizes and to account for substantial shaft misalignment and eccentricity in the shaft. Its durability ensures a long work life and that it won’t be damaged during installation

3) Versatile – Performs well in dry applications, on rotating shafts and oscillating shafts, and at high speeds over 3000 FPM.
