Rotary Seal, inside sealing for high velocities RSI

Product catalog summary
Overview: The document provides technical specifications and guidelines for the Hunger RSI rotary seal, designed for high-velocity applications with inside sealing. It includes details on materials, application range, design hints, surface finish, and fitting instructions.
Specifications: The RSI rotary seal consists of a highly wear-resistant PTFE-compound slide ring and O-rings made of Fluoro Rubber Monomer. It is available in single-acting and double-acting versions. The seal requires additional axial fixing to ensure dynamic movement occurs at the internal diameter. Recommended surface treatments include hardening to approximately 56 HRC or hard chromium plating.
Materials and Application Range: The seal is suitable for applications with limited installation space, particularly in machine tools. It is designed to handle static pressures up to 400 bar and dynamic pressures up to 360 bar, with a temperature range of -30°C to +220°C.
Design and Surface Finish: The document provides guidelines for surface quality, including Ra and Rt values for sliding surfaces, groove bases, and sides. A split installation housing is necessary for fitting the seal axially.
Order Information: An example order for a standard version is provided, with a reference number and dimensions. The design table lists various dimensions and specifications for different seal sizes.
Recommendations: The document suggests pressure compaction of the shaft surface using the HUNGER Schleifmittel GmbH method for optimal performance.

Rotary Seal, inside sealing for high velocities RSI-1

Rotor-Dichtsatz, innendichtend Rotary Seal, inside sealing schnellaufend / for high velocities Rotor-Dichtsatz, schnellaufend, innendichtend Rotary Seal for high velocities, inside sealing Der Hunger Rotor-Dichtsatz RSI besteht aus einem Gleitring aus höchst verschleißfestem PTFE-Compound und drei (doppeltwirkend) bzw. zwei (einfachwirkend) O-Ringen aus Fluorkautschuk, welche die Vorspannung der Dichtlippen erzeugen. The Hunger rotary seal type RSI consists of a highest wear-resistant PTFE-compound slide ring and three (double-acting) or two (single-acting) O-rings made of Fluoro Rubber Monomer, which provide the pretension of the sealing lips. Durch zusätzliche axiale Verklemmung der Dichtung wird sichergestellt, daß die dynamische Bewegung am Innendurchmesser erfolgt. Additional axial fixing of the seal ensures that dynamic movement takes place at the internal diameter. Je nach Anforderung und Betriebsbedingungen empfiehlt sich eine Behandlung der Gegenlauffläche, wie z. B. Härten auf ca. 56 HRC oder Hartverchromen. Depending on the specifications and operating conditions it is recommended to have the running surface hardened to approx. 56 HRC or hard chromium plated.
