NT Lip seals are reliable rotary shaft seals which find their use in challenging and extreme conditions. They are characterised by good chemical resistance, high temperature resistance and high pressure and load capacity. Our NT Lip Seals have good dry-running properties and can be used at high peripheral speeds. We also have special materials which are best suited for abrasive media.
NT Lip Seals are installed in housings in differing arrangements with intermediate rings, the setup depends on the application and requirements. The whole arrangement is then clamped axially via the press ring.
The shaft hardness must be at least 50 HRC
