V-Rings play an important role in sealing shafts against unwanted foreign materials such as grease, dirt, dust, and moisture that might otherwise penetrate an oil seal. These solid seals also serve to keep lubricants inside with the shaft and bearings. Although they are beneficial in a range of applications for their durability and the strength of their tight-fitting grip, V-Rings are particularly useful in situations where the shaft is not perfectly aligned. This is because these axial face seals have very wide tolerances, enabling them to adapt to movement in the shaft while still performing well and creating a uniform shape.
A V-Ring can function as a seal lip or as a centrifugal disc. Commonly, applications use V-Rings in conjunction with oil seals, radial shaft seals, or another seal type as a pre-sealing component for shafts and bearings.
