V-ring seals are all-rubber seals used primarily to exclude dirt and other contaminants. They are stretched over shafts and seal against the side of housing or another machine component.

What is v-Ring?

V-rings – Axial seals for shafts and bearings. V-rings seal axially against a counter-face. This type of seal has proved to be reliable and effective against dust, dirt, water and oil splash and other media. The V-ring also reduces wear and extends the service life of the oil seal and bearings.

What is the function of V-ring?

The function of a V-ring is to exclude dirt, water, or other aggressive media from entering bearing housings while also retaining grease. The V-ring stretches over the shaft and assumes a tight interference fit.

How do V-ring seals work?

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 to help extend the life of bearings, oil seals, and shafts.

Can V seals can be used as a replacement for oil seals?

Designed with a long, flexible lip, the V-ring can act as a face seal, a lip seal or slinger. The counterface should be metal and can be the end of a gearbox housing, a washer, a suitable steel stamping, even the back of an oil seal. Generally no seal bore is required and no shaft preparation is needed.
