Front seals / V-rings: All standard profiles - GUMAPLAST VP

Seals have a crucial influence on the system’s performance. The life and reliability of what is often considered a simple component can make a difference to your products and operations.

Front seals are elements that seal the medium from the front on rotating machine parts and prevent the ingress of dirt, moisture and other unwanted materials from entering the case or any desired area while retaining the lubricant.

V-ring specifications

Operation principle of the Front Seal / V-rings

The V-ring is an axial elastomeric seal for rotary shafts and bearings. It rotates with the shaft and seals axially against a stationary counterface perpendicular to the shaft. This type of seal has multiple applications that have proven to be reliable and effective in the suppression of dust, dirt, water and oil splash, and other media.

The ring consists of three parts:
a) The body of the seal itself, installed with interference to the shaft,
b) The joint (“hinge”), which acts as a spring connection between the body and the lip,
c) The conical and flexible sealing lip that provides a dynamic sealing against the surface.

The friction surface can be the sidewall of the bearing, washer, or any type of case.

VA seals

VA-ringovi

VA type of seals

It is used for lower pressures and it serves as an axial sealing rod with a very short mounting length, which is clamped on the shaft. The flexible sealing lip seals a counterface perpendicular to the shaft, preventing dirt, dust, and splashing to enter the structure.
