Introduction
Rubber V-rings are unique all-rubber seals for rotating shafts.
Rubber V-Rings are an axially acting rubber sealing ring. Unlike ordinary rotating oil seals, V-rings rely on their elastic sealing lips to form an axial sealing effect. The sealing lip has good mobility and adaptability, so it can compensate for larger deviations and angle deviations than other seals.
Rubber V-rings can be used for pressureless axial sealing of rotating shafts and bearing cap surfaces. Its function is to prevent the intrusion of external dirt and the leakage of internal grease, and the middle connection part can ensure that the sealing lip exerts a slight pressing force on the sealing surface to achieve effective sealing.
Application scenarios of Rubber V-Ring
1
Automobile industry
Rubber V-rings are often used for sealing components such as automobile engines, transmissions, and hydraulic systems.
2
Machinery manufacturing
In various mechanical equipment, V-shaped sealing rings are used for sealing bearings, transmission devices, pumps, etc.
3
Chemical industry
Rubber V-rings play an important sealing role in chemical equipment, pipelines, and valves.
4
Oil and natural gas
V-shaped rubber rings are used for oil and gas sealing and leakage prevention in oil wells, pipelines, and valves.
Benefits
Simple – Little prep required when installing. Simply ensure the shaft is clean try, applying 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 the counterface with little pressure and friction.
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.
Versatile – Performs well in dry applications, on rotating shafts and oscillating shafts, and at high speeds over 3000 FPM.
Options
We offer V-Rings in 3 styles (VA, VS, and VL) and two materials; NBR (black) and Viton® (brown).
VA: The most common style. Available in a wide range of sizes from 2.5MM ID to 1810MM ID. They have a short mounting length and are commonly used in gearboxes, electric motors, and drives.
VS: Available from 4MM ID to 180 MM ID and typically found in agricultural and automotive environments.
VL: Available from 99MM ID to 540MM ID. They have a short mounting length and are designed for use when the sealing house is limited or as part of a labyrinth sealing application.
