V-rings
The V-Ring seal is designed with a long flexible lip, the seal acts like an axial slinger. It can retain heavy lubricants and is highly effective in excluding contaminants. The V-Ring can be used as the primary seal or as a secondary back-up seal. The rubber V-ring can be stretched over flanges, couplings and sometimes over complete bearing housings without any unit disassembly.
Because of the design of V-rings, it can perform well in dry applications. The capability of handling a greater amount of eccentricity and misalignment than most lip seals have shown the advantage of using a V-ring.
Materials
Nitrile rubber is the standard grade. It has excellent resistance to wear and withstands the majority of media to which a seal is exposed. Temperature range -40°C to +100°C.
Fluorocarbon rubber (VITON®) is used where the operating temperatures are more than +100°C, and in conjunction with certain aggressive chemicals. Temperature range -23°C to +150°C in dynamic applications, -45°C to +230°C in static applications.
V-Ring Profiles
V-Rings are now manufactured in a number of profiles. VS and VA differences only with regard to the rear face. The VS has a conical rear face, whereas the VA has a plain rear face which demands less seal space. VS sizes are range from VS005 – VS199. VA sizes are range from VA003 – VA600. V-3, V-4 and rings greater than V-200 are manufactured in profile type A only. V-Rings larger than V-1000 are manufactured to order.
