123 RSR™ SEAL High-pressure “Dry Rod” Seals R S R ™ UNIQUE SHAPE MEANS SUPERIOR PERFORMANCE Greene, Tweed’s RSR™ rod or piston seal features a specially engineered elastomer profile that provides exceptional “dry rod” sealing under dynamic conditions. The RSR’s endless, trapezoidal wedge-shaped back-up ring has an exceptionally wide shear section to ensure excellent resistance to extrusion. In addition, the back-up ring’s shape generates a force vector under pressure, and fewer sealing problems. RSR Piston Seal The RSR seal excels in brake applications where the trapezoidal shape provides a natural pull back on the brake piston, therefore making piston design less complicated. FEATURES & BENEFITS thereby eliminating the extrusion gap. The result: very low leakage • Combination of elastomer and back-up ring design ensures excellent resistance to extrusion and elastomer nibbling • Specially designed elastomer heel provides pull back in some dynamic applications, making the seal perfect for brake applications • Provides exceptional dry rod sealing in dynamic applications resulting in extremely tight leakage control • Door actuators • Thrust reverser systems applications RSR™ CONFIGURATIONS RSR™ seals are available in standard, zero, one and two back-up gland sizes per MIL-G-5514/AS4716. © 2012, Greene, Tweed all rights reserved All trademarks are property of their respective owners. 06/12-GT DS-US-AS-035 • High-performance utility actuators
