Description

V'Rings are seal parts that are very often combined with other types of seals such as radial shaft seals. They are also used as the primary seal in other cases. As they offer optimal axial sealing, V'Rings are used to protect the metal parts against dirt, grease, oil and dust. They are frequently used in mechanical transmissions, rolling-mills, machine tools, etc.

As a technical component made completely of rubber, V'Rings have three parts:

? the body: the thickest part of the seal, which is clamped in place on the rotating axle and permits rotation.

? the hinge: the part connecting the sealing lip to the body of the seal, which provides a certain amount of flexibility,

thus preventing significant position stresses.

? the sealing lip: the part that compensates for radial runout (angle deviations in the rotating axle) as well as significant tolerance gaps other than those recommended by its flexibility. It therefore ensures sealing on the opposing metal surface.

Stretched on the shaft, the V'Ring must be positioned at a precise distance in relation to the opposing metal friction surface (or back) to guarantee optimal sealing under axial pre-stressing of the sealing lip. The V'Ring turns with the rotating shaft and depending on the circumferential speed, the centrifugal force acting on the sealing lip repels it on the outside, which reduces compression. Beyond a certain speed, the sealing lip must not come into constant contact with the opposing metal wall, as sealing is not guaranteed.
