O-ring seal S series

plasticfor rotating shaftsfor the food industry

The corrosion-free material properties mean that the plastic seals from GMN are particularly well-suited for protecting from watery liquids. Polyoxymethylene has a high resistance to a variety of acids (lactic acids), chemicals and fungi. GMN non-contact plastic seals are approved for the food industry. The S design is particularly suited for use with normal spray load for rotating shafts and hubs. Technical Data: Outer and inner ring: high quality Polyoxymethylene plastic Temperature range: -40 ° – 60 °C (special design with O-ring up to 80 °C) Shaft diameter: 10 – 160 mm (customized solutions available upon request) Width: 10, 12, 15 mm (depending on size) Sealing gap: Conical Axial play: Sax = 0.8 mm (total axial movement of the seals from one end position to the other) Greased seals: All types in the S design are also available with a greased sealing gap for improved protection from dust. (Ordering designation: SdxDxB greased) Characteristics: Frictionless: Thanks to their non-contact design, GMN labyrinth seals guarantee completely frictionless operation. Wear-free: GMN seal components work completely wear-free and offer an unlimited service life. Abrasion-free: The non-contact design of GMN seal components guarantees operation free from abrasion that fulfills the highest cleanliness requirements. (Approved for the food industry.) Effective: The small distance between the outer and inner ring guarantees highly effective sealing and very good protection from fouling. Heat-free: Because no friction heat is generated, neither the seal nor the adjacent components or the lubricant are subjected to thermal loads.
