V-Rings

Rubber ring for shafts requiring a dynamic seal (primary or back-up) in the axial direction. The body of V seals rotate with the shaft and holds itself in position by its elastic fit on the shaft. Sealing is produced by the contact between the lip and the counterface. Additionally, the V Series rings has good sealing action when the shaft is eccentric and/or there is some misalignment. Combined with radial shaft seals, these axial face seal designs provide excellent excluding characteristics against all types of liquids, greases, oils, dirt and other foreign materials. V-Rings are available in both Buna ‘N’ and Viton .

Typical applications: Conveyor Rollers, Appliances, Motors, agriculture, wheel hubs, appliances, pumps and gear boxes etc.
