V-rings are also known as V-seals. All rubber seals, which are directly installed on to a shaft - to seal against housing face, a bearing and/or the back of a shaft seal. They are used chiefly for protection of bearings or other key parts from any contamination, as well as for retaining grease. V-rings can effectively function in dry applications – those with very low torque.

V-rings, generally speaking, consist of three major parts - a body, a hinge and a conical self-adjusting lip. While in service, the seal’s elastic body rotates along with the shaft. VA style V-rings are probably among the most common types and are employed in appliances as well as conveyor rollers.

Widening the body of the above type will result in the expanded body plus tapered heel of the V-ring in place on the shaft. These types of V-rings are utilized in automotive applications. V-rings can well tolerate greater radial variation than a traditional shaft seal. V-rings can also tolerate greater ‘shaft-to-bore’ misalignment and a greater ‘dynamic run-out’ than any standard shaft seal. It can function effectively as both a seal & a slinger.

V-rings are less expensive than your traditional shaft seals. V-rings are usually mounted on and also rotate with the shaft. They can be stretched out and easily fitted over a flange during installation process - a valuable characteristic, especially during repair. V-rings are usually made of nitrile rubber or the one recommended by the client. V-rings of fluoro rubber should be utilized for applications with a higher temperature range.
