V ring seals are mounted on shafts and their thin tapered lip seals against a surface counterface at right angles to the shaft.
V ring lip seal.
All rubber v rings fig 1 or just called v rings mvr axial shaft seals fig 2 a metal cased v ring seal.
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.
It works by stretching over the shaft to create a tight seal along the shaft while the flexible lip seals lightly against the counterface at a right angle to the shaft.
The v ring works well on its own and excels when combined with rotary shaft seals and helps extend the life of bearings oil seals and shafts.
V ring seals are axial shaft seals available in a wide range of sizes and appropriate for many applications.
