Product Description:
The use of VRM axial seals for applications in which avoiding water entry (or any other contaminants) is critical, such as in heavy equipments for earth moving in mining and construction work, or in marine environment. The most common use of these axial seals is for applications such as industrial gearboxes, water pump, power transmission systems, building site machinery, electric motors and rotary shafts amongst many others.
Axial seals are specifically designed to be perpendicularly fixed to the shaft at a predetermined distance from the stationary counter-face. During the rotation, the lip sticks against the counter-face under a calculated pressure that enables the perfect sealing. Furthermore, we must stress the deflector role of axial seals, taking advantage of the centrifugal force in order to improve the required sealing effect.
VRM1 and VRM2 axial seals – as well known as Gamma Rings or Gamma Seals – combine the ability of mechanical seals to work at high speed and the simplicity of oil seals.Standard materials
Elastomer sealing element: NBR70 black, FKM70 brown, Other elastomer materials are available on request.
Metal ring: deep-drawn, coated steel, galvanised, also available in rust and acid-resistant steel.Advantages of VRM axial seals
simple sealing element with narrow installation width
sealing against grease, dirt, dust and water spray
additional sealing function due to the centrifugal action of the metal ring
good in combination with rotary shaft seals
low demands on the sliding surface with regard to the surface quality
simple installation
the metal ring protects the elastomer sealing element against damage
the friction decreases with increasing peripheral speed as a result of centrifugal force
good dynamic sealing action
no additional axial stop required
