V Ring Seal

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 ring seal.

The construction of a v ring seal is divided into three parts. V ring seals are mounted on shafts and their thin tapered lip seals against a surface counterface at right angles to the shaft. They are specifically designed to protect the primary seal from contaminants. 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.

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 rings are flexible rubber seals that stretch fit onto the shaft and rotate with the shaft against a counter face. Freudenberg sealing technologies offers water deflectors in various designs that can be used for low load up to heavy duty areas of application for example the new merkel enviromatic deflector. All rubber v rings fig 1 or just called v rings mvr axial shaft seals fig 2 a metal cased v ring seal.

Made of ptfe these v ring packing seals have excellent chemical resistance and withstand a wide temperature range of 110 f to 500 f. 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. Skf supplies two types of v ring seals.

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. Water deflectors v rings protect sealing elements against grease oil or water spray as well as dust and other media. These seals are more info. V ring seals are axial shaft seals available in a wide range of sizes and appropriate for many applications.

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. The design of the seal lip is crucial for the high functionality of a v ring seal or deflector.
