Greene, Tweed’s RSA Seal® (Rubber-Spring Actuated) offers low compression set, high tear resistance, modulus, abrasion resistance and long life in rugged operating conditions. The RSA seal with full heel bearing is a compact, pressure-compensating U-type seal made from a proprietary high-molecular weight elastomer formulated for low-temperature performance. It incorporates an O-ring energizer to apply uniform radial loading on the seal’s back-beveled lip. The Avalon® heel bearing serves as a low friction, high-shear strength stabilizer to maintain exact lip-point interference between the seal and sealing surface. This results in no leakage during ovalization and breathing during deflection of the strut.
