Freudenberg Sealing TechnologiesSimrit product division has developed a friction-optimized seal that fits in existing standard sealing grooves. Designed to provide more consistent performance, the combined elastomer/polytetrafluoroethylene (PTFE) system offers low breakaway force, improved durability, and temperature resistance for dry-running piston-type systems such as air brakes or pneumatics. With its very low initial breakaway torque and friction, the dual-material seal also provides high-temperature consistency and a comparable installation to that of an O-ring, including direction independence, “twist-safe” performance, and gap extrusion resistance. It also offers increased design freedom, as a variance of geometries and diameters are available to minimize friction differences even when using all production tolerances. The PTFE layer is bonded to an elastomer, which then can be bonded to a solid carrier if required. Freudenberg-NOK found that such a concept could be used to minimize friction and improve the overall comfort at gear changing in automatic transmissions.
