The Gerromatic radial shaft seal from Freudenberg Sealing Technologies comprises a stainless steel retaining element and a high-performance PTFE wave-shaped sealing lip that runs in a novel 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. The Gerromatic radial shaft seal is available via Dichtomatik Ltd, the exclusive provider for Freudenberg’s food and beverage related sealing products in the UK.
The seal is intended for use in axially accessible installation spaces, whereby the metallic clamping ring enables an exceptionally tight fit. The Gerromatic rotary shaft seal withstands a high-pressure load of up to 8 bar, and temperatures of between 80°C and +200°C. In other applications, a sliding speed of up to 25 m/s can be achieved.
