A V-ring consists of a seal body, a flexible, conical-shaped sealing lip and an integral, resilient "hinge". It is stretched and installed
Directly on the shaft, where it is held in place by the inherent tension of the seal
Body. It rotates with the shaft and seals axially against a stationary counterface.
The counterface can be the end face of a bearing, a washer, stamping, bearing
Housing, or even the metal case of a radial shaft seal.
The flexible sealing lip applies contact pressure against the counterface that is
Relatively low but sufficient enough to maintain the sealing function. The light
Contact pressure even enables the seal to run dry in some low-speed applications resulting in insignificant torque drag or heat build-up. The contact pressure varies with the fitted width.
The flexible lip and hinge provide adequate sealing even in applications with
Considerable end play and shaft misalignment.
As a result of centrifugal force, the contact pressure of the lip decreases as speed increases. This means that friction losses and heat are kept to a minimum, resulting in improved wear resistance and extended service life. The power loss reaches its maximum at a shaft speed of approximately 12 m/s (2 360 ft/min) and is thereafter gradually reduced up to 20 m/s (3 900 ft/min), where it will decrease to zero. The V-ring then serves as a gap-type seal and deflector.
VA, the most common type of V-ring, has a standard cross section and straight back sideface. VA is typically used
To protect bearing arrangements in gearboxes, electric motors and drives.
VS, that has a standard low cross section, tapered back face and wide body,
Providing a firm hold on the shaft. VS is commonly used in agricultural and
VL, designed with a very compact axial cross section. VL is commonly used in
Confined spaces to replace labyrinth seals.
Main V-ring functions
V rings are suitable for both grease and oil lubricated applications. For sealing
Grease lubricated bearing arrangements and protecting against contaminants, the
V-ring should be arranged outside the housing cover or housing wall. Dust, water
Spray and other contaminants can be excluded in this position. The V-ring can also act as a grease valve, where used grease or excess new grease
Can escape between the counterface and the sealing lip. The installation of two
Opposing V-rings can be used in applications where lubricant retention and contaminant
Exclusion are of equal importance.
If V-rings are used to retain oil, they should always be located axially on the shaft on
The lubricant side.
V-rings should not be submerged in the application medium.
