V-ring seals are unique all-rubber seals for rotating shafts. They are used in all kinds of industrial rotating applications as cost-effective contaminant barriers for optimized bearing protection. V-rings have an interference fit on the shaft and are, by design, easy to install. They can be stretched and, depending on size, pushed over other components like flanges, pulleys or even housings when replacing a seal. V-rings rotate with the shaft, seal axially against a stationary counterface and act as flingers. The counterface can be the end face of a bearing, a washer, stamping, bearing housing, or even the metal case of a radial shaft seal. The V-ring offerings from SKF comprises five standard designs that are available in SKF-developed nitrile rubber (NBR) and fluoro rubber (FKM) compounds.
