V-Rings

Rubber V-Rings for shafts requiring a dynamic seal (primary or back-up) in the axial direction. The body of V seals rotates with the shaft and holds itself in position by its elastic fit on the shaft. Sealing is produced by the contact between the lip and the counterface. Additionally, the V Series rings have good sealing action when the shaft is eccentric and/or there is some misalignment. Combined with radial shaft seals, these axial face seal designs provide excellent excluding characteristics against all types of liquids, greases, oils, dirt, and other foreign materials. V-Rings are available in both Buna N and Viton.

Description

Typical applications: Conveyor Rollers, Appliances, Motors, agriculture, wheel hubs, appliances, pumps, and gearboxes, etc.

V-rings are versatile seals that can be used to retain grease lubricants, but with proper surface preparation, they can also run dry with minimal torque loss and a long service life. Due to their high elasticity, smaller V-rings can stretch up to 2.5 times their original diameter, allowing them to be easily installed on shafts without requiring disassembly of the unit, even over flanges, pillow blocks, or other components. A single V-ring size can fit multiple shaft diameters, both in English and metric units, and can accommodate various media across a broad temperature range from -40°F to 392°F, depending on the material selected.

How do Rubber V-Rings protect rotating components?

Rubber V-Rings act as an axial seal mounted directly onto the shaft, where the sealing lip presses against a fixed surface to prevent dust, moisture, and contaminants from entering sensitive components like bearings or gears.

Why choose V-Rings for dynamic sealing needs?

Thanks to their flexible lip and centrifugal geometry, V-Rings maintain low friction and adapt to misalignment. At higher speeds, the lip flings away particles, self-cleaning as it rotates.

How easy is it to install a V-Ring?

Extremely easy, just stretch it over the shaft, and it fits snugly against the counterface. No grooves or complex housing required. This simplicity minimizes downtime and installation costs.

In what environments do V-Rings excel?

They thrive in demanding settings—agricultural machinery, motors, gearboxes, and conveyor systems. They're perfect as auxiliary seals, reinforcing the performance of primary shaft or bearing seals.

Are there V-Ring variants for different applications?

Yes, including different profiles like VA, VS, VL, and VE, each tailored for factors like size constraints, rigidity needs, and heavy-duty machinery applications.
