Standard Lip Seals
Mechanical seals
Radial Lip Shaft Seals
The Standard Loaded Lip Seal Is The Most Widely Used Design Of Loaded Lip Seal. By Energizing The Sealing Lips With An Endless O-Ring, You Are Assured Of Uniform, Positive Lip Contact And Excellent Low Pressure Sealing. The Seal Depth Is Equal To The Radial Width, Which Results In A Square Design. Standard Loaded Lip Seals Can Be Widely Used To Interchange With Existing Hydraulic Packing And/Or O-Rings Without Changing Dimensions.

SURFACE ROUGHNESS:
The contact surface area of the shaft should adhere to Ra = 0.2 – 0.8 μm. The surface roughness should lie within the stipulated
ranges. Shaft surfaces with higher roughness create increased wear on the sealing edge and lead to a decrease in the lifespan.
Even very small defects could be enough to increase the thickness of the film, which could eventually rupture the meniscus and
cause leakage. It is also important to avoid spiral or groove grinding marks. This could cause a pumping effect or dry running
resulting in leakage or failure.
Mechanical Seals
When should I use a lip seal, rather than a “face seal”?
The advantage of lip seals is that they require very little space. They do have limitations on pressure, speed, minimal, and media compatibility. As long as the application is within the parameters of the materials of construction they can last many years. Mechanical face seals are required when the application is over 25 psig but will require more space.
We can help you to have the success you want out of your lip seals. Materials of construction include Nitrile, Viton, FKM, PTFE, EPDM, and Neoprene.
