Rubber Spring Actuated Scraper Series
The RSA (Rubber Spring Actuated) scraper provides superior contaminant exclusion in the most rugged service conditions. A compression-activate d device, the RSA scraper uses a low com-pression set rubber O-ring “spring” to maintain the constant radial compression that results in continual contact with both the rod and gland diameter—even in extreme cold, under high linear speeds and during heavy side loading. The RSA scraper’s unique radial design virtually eliminates rod wear and prevents rolling or twisting while retaining sufficient upstream fluid to assure lubrication of the primary seal, resulting in extended service life. Additionally, the RSA scraper can be wave cut for ease of installation for nonstandard applications. The RSA scraper is manufactured in a broad range of high modulus elastomers including hydrogenated nitrile and our proprietary, low-temperature urethane. Its energizer is available in a variety of elastomeric materials, each compounded for service in specific fluids and temperatures. FEATURES & BENEFITS Maximum exclusion capabilities for elimination of contamination ingression Excellent wear resistance resulting in extended service life Seal design virtually eliminates rod wear and rolling and twisting, resulting in extended service life Offered in a variety of configurations to meet most of the standard glands used in today’s existing aircraft
