Product catalog summary
Overview: The document provides technical specifications and guidelines for the Hunger WDA shaft seal, designed for outside sealing of permanently rotating shafts. It highlights the material quality, design features, and application recommendations.
Specifications: The WDA shaft seal can operate at sliding speeds up to 0.8 m/s. The gap size should not exceed 0.2 mm, and the surface finish of the sliding surface should be Ra 0.1 - 0.3 µm. For optimal performance, the running surface may be hardened to approximately 56 HRC or hard chromium plated.
Materials and Application Range: The seal is suitable for use in rotary feed units at high speeds and is designed for easy fitting. It is applicable in environments involving hydraulic oil, water-oil, and water-glycol fluids.
Design and Fitting Instructions: The elastic ring is expanded using a round-shafted fitting tool and snapped into the groove. Lubrication should be applied only on the sliding surfaces.
Surface Quality: Sliding surfaces should have a roughness of Ra 0.1 - 0.3 µm and Rt ≤ 1.5 µm. The groove base should have a roughness of Ra ≤ 0.8 µm and the groove sides Ra ≤ 2.3 µm.
Order Information: The document provides a table with standard dimensions and reference numbers for ordering. Further dimensions are available upon request.

Wellendichtring, auftendichtend Shaft Seal, outside sealing Der Hunger Wellendichtring WDA ist als Dichtelement fur permanent drehende Wellen einsetzbar und kann beidseitig abdichten. Aufgrund der besonderen Materialqualitat und der op-timierten Dichtungsgeometrie kann dieses Dichtelement bis zu einer Gleitgeschwindigkeit von 0,8 m/s eingesetzt werden. Das SpaltmaG sollte 0,2 mm nicht ubersteigen. Die Rauhigkeit der Gegenlaufflache sollte Ra 0,1 - 0,3 pm sein. Je nach Anforderung und Betriebsbedingungen em-pfiehlt sich eine Behandlung der Gegenlaufflache, wie z. B. Harten auf ca. 56 HRC oder Hartverchromen. The Hunger shaft seal type WDA is applied as a sealing element for permanently rotating shafts and is capable of sealing on both sides. Due to the use of special materials and an optimum seal profile it can be used for speeds up to 0.8 m/s. The gap size should not be more than 0.2 mm. The surface finish of the sliding surface should be Ra 0.1 - 0.3 pm. Depending on the specifications and operating conditions it is recommended to have the running surface hardened to approx. 56 HRC or hard chromium plated.
