V Ring Seal

A v ring is a solid rubber seal used on shafts to prevent dirt moisture and other unwanted material from entering an oil seal housing or any other desired area while simultaneously keeping lubricants in.

V ring seal.

V ring seals are mounted on shafts and their thin tapered lip seals against a surface counterface at right angles to the shaft. V rings a v ring seal is a one piece seal which is mounted on a shaft and seals axially against a counterface and normally rotates with the shaft. Made of ptfe these v ring packing seals have excellent chemical resistance and withstand a wide temperature range of 110 f to 500 f. No special demands are placed on the surface finish of the shaft seating and the v rings act as flingers since they have an interference fit on the shaft and rotate with it.

Water deflectors v rings protect sealing elements against grease oil or water spray as well as dust and other media. Skf supplies two types of v ring seals. V ring seals sometimes called rotary shaft seals are installed on the shaft of a hydraulic cylinder to prevent fluid leaks and keep contaminants such as dirt and moisture from entering the housing. V rings are flexible rubber seals that stretch fit onto the shaft and rotate with the shaft against a counter face.

The construction of a v ring seal is divided into three parts. V ring seals are axial shaft seals available in a wide range of sizes and appropriate for many applications. Stack as many v rings as you need to fill grooves in valves pumps and cylinders. Keeping bearing lubricant clean reduces wear and extends the bearing s working life.

Begin with a male and female adapter then add v rings between them to fill the space. While the very flexible seal lip of a standard v ring seal lies flat against the counter face which is generally sufficient for secondary applications the fem optimized seal lip of the merkel enviromatic exhibits a completely new behavior. They are specifically designed to protect the primary seal from contaminants. They are made entirely of rubber material and comprise a body and a conical shaped sealing lip which is joined to the body by means of a resilient hinge v rings are mounted on and rotate with the shaft.

V ring seals are unique all rubber seals for rotary shafts. These seals are more info.
