V-ring seals are attached to shafts and have a narrow, tapered lip that seals against a surface (counterface) at right angles to the shaft. There are no specific requirements for the surface quality of the shaft sitting, and the V-rings function as flingers since they have an interference fit on the shaft and spin with it.
Misalignment of the shaft with regard to the counterface is permitted, and V-rings enable dependable sealing even if the shaft is out-of-round or spins eccentrically.
When using V-rings, keep in mind that the amount by which the shaft can be shifted axially is controlled by the V-allowed ring's displacement relative to its counterface.
V-rings are entirely composed of elastomer, with no fabric or sheet metal insert. As a result, they are extremely simple to install. They can be stretched and pushed over other components of the arrangement, such as flanges, pulleys, or even housings, depending on their size. This is a highly essential trait, especially when it comes to repairs.
