Gerromatic radial shaft seal minimises wear and boosts service life
03 August 2020
The Gerromatic radial shaft seal from Freudenberg Sealing Technologies is designed to minimise wear and maximise service life.
Available via Dichtomatik, exclusive provider for Freudenberg’s food and beverage related sealing products in the UK, the seal comprises a stainless steel retaining element and a high-performance PTFE wave-shaped sealing lip that runs in a sinusoidal pattern on the shaft surface. As the shaft rotates, each point of the sealing lip repeatedly covers a new area of the shaft that is wetted with medium.
It is intended for use in axially accessible installation spaces, whereby the metallic clamping ring enables an exceptionally tight fit. The seal withstands a high-pressure load to 8 bar and temperatures between -80 and 200°C. In other applications, a sliding speed to 25m/s can be achieved.
