V Rings

V rings manufacturers in Mumbai

The MECH V-RING is a unique all-rubber seal for rotary shafts. The V-Ring provides a perfect solution to prevent the ingress of dirt, dust, water or combinations of these media while positively retaining grease. With its unique design and performance the V-Ring protects a wide range of bearing types. It can also be used as a secondary seal to protect primary seals that do not perform well in hostile environments. It has been used successfully by OEM and the replacement market world wide in a broad range of applications. V rings manufacturers in Mumbai, India to supply entire world of V ring shaft seal since 1964 according to ISO standards and specifications with assurity of industrial features.

Selection of Rubber

When selecting the correct material i.e. type of rubber compound it is necessary to take the following requirements into account:

  • good chemical resistance
  • good resistance to high and low temperatures
  • good resistance to ozone and weathering
  • It is also necessary to consider the need for the following attributes
  • high resistance to wear
  • low friction
  • low compression set
  • good elasticity


Pressure Range: up to .5 MPa (74 psi)

Temperature: -40 to +200ºC (-40 to +392ºF)

Velocity: 30 m/s (100 ft/s)


V-Ring is normally long-drawn-out 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 counter face, at right angles to the shaft. The counter face can be the end face of a bearing or a washer, stamping, bearing housing, or even the metal case of oil seals. The sealing lip is flexible and applies only a relatively light contact pressure against the counter-face and yet is still sufficient to maintain the sealing function. The low contact pressure (that varies with the fitted width) allows the seal to run dry in many applications.

Due to the centrifugal force, the contact pressure of the lip decreases with increased speed. This means that frictional losses and heat are kept to a minimum, resulting in excellent wear characteristics and extended seal life. Once breakaway torque is overcome, the power losses reduce steadily until around the 10 -15 m/s band when they reduce quite quickly. In the 15 – 20 m/s band the losses reduce to zero and the V-Ring then serves as clearance seal and deflector.

The flexible lip and hinge allow the V-Ring to function even in the presence of a certain amount of run-out, eccentricity and shaft misalignment. Contact our local company for advice on these and other application issues.

V-Rings are made entirely of rubber without fabric or sheet metal reinforcement. They are, therefore, particularly easy to install. V-Rings can be stretched and, depending on size, installed over flanges, pulleys and bearing housings without costly dismantling.

V-Rings are available in various standard cross-sections to meet various space and application requirements.
