What are Rotary Rubber Seal V Rings
Rotary Rubber Seal V Rings are made of soft rubber material and have a V-shaped cross-sectional profile. This special cross-sectional shape allows the ring to adapt to the movement of the rotating shaft and provides good sealing performance. The inner side of the V-ring is in close contact with the rotating shaft, forming a sealing interface to prevent liquid or gas from leaking from the axial direction. At the same time, the outside of the V-ring is in contact with mechanical components or sealed housings to prevent impurities from entering. Rubber Seal V rings are commonly found in hydraulic systems, engines, pumps, compressors, transmissions, and other equipment.
The key benefits of rotary rubber seal v rings
- Excellent sealing performance: Due to its V-shaped cross-section design, the Rotary Rubber Seal V-ring can provide excellent sealing performance. They can effectively prevent liquid or gas from leaking from the rotating axis and ensure the normal operation of the system.
- Adaptable: Rotary Rubber Seal V-rings are suitable for various types of rotating shafts, including high-speed rotating shafts. These rings adapt and provide reliable sealing regardless of shaft diameter or rotational speed.
- Wear Resistance and Durability: The Rotary Rubber Seal V-ring is usually made of high-quality rubber material with excellent wear resistance and durability. They can withstand prolonged use and repeated rotational motion without failure, extending the life of the equipment.
- Chemical resistance: These ring materials usually have certain chemical resistance and can maintain stable sealing performance in various chemical media. This makes Rubber Seal V rings very useful in applications involving chemicals.
- The technology is simple. Low friction and minimal power loss. In smaller power plants, this can be important. The lip exerts very light pressure on the mating surface.
- The seal resists damage during installation. One size covers multiple shaft sizes.
- Versatile application. The same applies to rotating or swivel axes and at high speeds above 3000 rpm.
Rubber V-Rings
The function of the V-ring is to prevent dust, water, or other corrosive media from entering the bearing housing while retaining grease. The V-ring extends over the shaft and provides a tight interference fit.
V-ring shaft seals utilize centrifugal slinger action to provide effective protection against dry and wet contamination. V-rings are used in conjunction with metal-cased radial seals to reduce wear and extend the life of oil seals and bearings.
V-rings also perform well in dry-running applications. Since it's all rubber and very stretchy, it can be stretched over flanges or other components for easy installation and requires minimal unit disassembly. It has very low torque resistance and heat build-up and does not require expensive mating surface preparation.
product information rotary rubber seal v rings
| Material description | The most frequently selected material is the purpose-made Nitrile rubber which has excellent all-around properties. For applications with temperatures above 100℃, or in chemically aggressive conditions, V-Rings made of fluorinated rubber (FKM) can be supplied. A wide range of rubber compounds is available and some of these are listed below. |
| Available Color | Black, brown, and so on |
| Material Strength | – good chemical resistance – good resistance to high and low temperatures – good resistance to ozone and weathering – high resistance to wear – low friction – low compression set – good elasticity. The V-ring is normally stretched and mounted directly on the shaft, where it is held in position by the inherent tension of the rubber body. It rotates with the shaft and seals axially against a stationary counterface, perpendicular to the shaft. The counterface can be the side wall of a bearing or a washer, stamping, bearing housing, or even the metal case of an oil seal. 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. |
