V Shaped Rubber Rings | Axial Shaft V-Seals for Bearing Protection
V Shaped Rubber Rings (often called V-Rings or V-Seals) are unique, all-rubber axial face seals designed to protect bearings and shaft journals from external contamination. Unlike traditional radial oil seals, V-Rings mount directly on the shaft and rotate with it, sealing axially against a stationary counterface (such as a bearing housing or metal washer). This "slinging" motion utilizes centrifugal force to reject water, dust, and abrasive particles, making them an essential primary seal in heavy-duty industrial environments.
The Centrifugal Protecting Sealing Principle
As the shaft rotates, the V-Ring's flexible lip exerts light axial pressure against the counterface. The centrifugal force generated by rotation creates a "slinging effect," actively throwing grease, moisture, and debris away from the sealing point. This mechanism allows the seal to run dry in many applications and provides an incredibly low friction torque, extending bearing life significantly.
Technical Capabilities & Profiles
We manufacture a full range of V-Seal profiles to match specific housing constraints and shaft speeds.
| Profile Type | Design Characteristics | Typical B2B Application Scenario |

| Type VA | Standard profile with a straight back. | Electric motors, gearboxes, and general machinery. |
| Type VS | Reinforced wide back for higher stability. | Rolling mills, heavy agricultural equipment, and mining machinery. |
| Type VL | Thin, slim profile for compact spaces. | Small household appliances and precision tool spindles. |
| Type VE | Large diameter heavy-duty design. | Large-scale power plants and heavy marine propulsion systems. |
