V-Ring MA

DESCRIPTION
V-ring MA is deflector seal designed for axial acting and made from an elastomeric materials.
The V-Ring prevent the ingress of dirt, dust or water into bearing on rotary shafts at the same time retaining the grease. It can be used as
secondary seal to protect primary seal in hostile environments.
The V-Ring is mounted stretched directly on the shaft, where it is held in place by the inherent
rubber forces. It rotates with the shaft and seals axially. It is in contact with an stationary counterface, perpendicular to the shaft.
The sealing lip is flexible and applies small contact pressure against the counterface allowing the seal to run dry in many applications
