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
