RSR™ SEAL

High-pressure “Dry Rod” Seals

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,
thereby eliminating the extrusion gap. The result: very low leakage and fewer sealing problems.

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

  • 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

APPLICATIONS

  • High-performance utility actuators
  • 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.
