V-ring seals

A V-ring is an elastomer axial seal. It is stretched onto the shaft, turns with it, and its lip runs against a face at right angles to the shaft, on a housing or on another component. It works as a flinger, keeping dust, water and particles out while helping hold lubricant in. Use it as the main barrier in dirty environments or as a secondary seal ahead of a radial shaft seal.

An SKF part number has a size number, the type abbreviation and a material letter. In 100 VA R, 100 VS R, 110 VA V or 100 VS V, VA and VS are two different designs, the number is the size based on shaft diameter, and the closing letter tells you the elastomer. Because one size comes in several types and materials, only the full part number pins down the seal.

When selecting, look at shaft diameter, surface speed, temperature, the kind of contamination and the condition of the counterface, which has to be flat, smooth and square to the shaft. At high speeds it is good practice to clamp the V-ring axially so centrifugal force does not lift it off. They are common on electric motors, gearboxes, pumps, fans, belt conveyors and farm machinery.
