Axial shaft seals V-ring seals

Detailed information about V-rings in the VR1, VR2, VR3 and VR4 designs and about technical data, size range and installation can be found in our catalog .

V-ring seals are available in four standard designs and two large size heavy-duty designs.

Series VR

V-ring seals are available in a large variety of designs and sizes to fit the requirements of most applications. V-rings are normally made of nitrile rubber. For applications where higher temperatures occur or where aggressive media are present, V-rings made of fluoro rubber should be used.

V-rings are mounted on and rotate with the shaft. The lip seals axially against a counter face, which is perpendicular to the shaft. The body has an interference fit on the shaft and holds the lip in position. V-rings can be stretched out and fitted over a flange during installation, which is a very valuable characteristic, especially in the case of repair. They can operate at sliding velocities up to 8 m/s. At velocities above 8 up to 12 m/s the V-rings need to be axially located.

V-ring seals are unique all-rubber seals for rotary shafts. 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.
