Rotary Seal, outside sealing RODA

Product catalog summary
Overview: The document provides technical specifications and installation guidelines for the RODA rotary seal, designed for sealing rotating components with an outside sealing mechanism. It highlights the compact design, material recommendations, and installation procedures.
Specifications: The RODA rotary seal is designed for space-saving applications with a profile width starting at 3.9 mm. It features a radial leakage/lubricant groove for low friction and high sealing efficiency. The gap between rotor and stator must be smaller than that of the RDA type due to the seal design. The RODI variant is preferred for its greater static contact surface.
Material Recommendations: The document suggests hardening the running surface to approximately 56 HRC or applying hard chromium plating, depending on specifications and operating conditions.
Installation Guidelines: The O-ring is inserted into the groove, and the sealing thrust ring is positioned using a round-shafted screwdriver or a strip of clean cotton cloth. For diameters smaller than 100 mm, heating the PTFE-Compound thrust ring to approximately 100°C is recommended for easier installation. The sealing set should be installed without lubrication, except on the sliding surface of the slide ring.
Application Range: The RODA seal is suitable for rotary feed units with minimal installation space and low friction, without support rings. It allows for smaller versions and simple installation.
Design Table: The document includes a design table listing dimensions and reference numbers for various sizes of the RODA seal, ranging from diameters of 50 mm to 280 mm.
Order Example: An example is provided for ordering a standard version of the RODA seal with a diameter of 130 mm, along with the reference number.

Rotary Seal, outside sealing RODA-1

Rotor-Dichtsatz, außendichtend Rotary Seal, outside sealing Rotor-Dichtsatz, außendichtend Rotary Seal, outside sealing Der schmalbauende Rotordichtsatz RODA ist speziell für die Abdichtung drehender Maschinenteile ausgelegt. The space-saving rotary seal type RODA is designed specifically for sealing rotating components. Ab Profilbreite 3,9 mm verfügt er über eine radiale Lekkage-/Schmierstoffnut in der Lauffläche, die für geringe Reibung, hohe Dichtheit und niedrige Losbrechmomente sorgt. From profile width 3.9 mm it has a radial leakage/lubricant groove in the slide ring surface which provides a low friction, high sealing effect with low break-away forces. Werkstoffbedingt müssen die Spaltverhältnisse zwischen Rotor und Stator enger als beim Typ RDA ausgelegt werden. The gap between rotor and stator must be smaller than that of the RDA due to the seal design. Der RODI weist eine größere statische Haftfläche auf und ist daher dem RODA vorzuziehen. The RODI is to be preferred to the RODA due to its greater static contact surface. 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.
