With the coordinated combination of 75 FKM 260466 and PGs, the challenges of sealing edge wear and shaft inlet can be mastered and operating life increased compared to other seal materials. The combination of a Simmerring® with an integrated encoder not only seals the shaft reliably but captures its rotational speed as well. Medium pressure seals, such as the BABSL, can be used in many applications including pumps and motors in hydro-units, mechanical power transmission gearboxes, and 2-stroke engines. Lower friction compared to conventional sealing lip profile: 15 to 20%. Early radial shaft seals utilized rawhide as the sealing element, and many elastomeric seal … The chemical structure of this elastomer (obtained by hydrogenating an appropriate type of NBR nitrile rubber) allows achieving, especially if vulcanized with a peroxide system, an average heat resistance 30°C above that of nitrile rubber, and an excellent abrasion resistance. The Freudenberg CASSETTE-S4 is the most advanced Freudenberg solution for construction and agriculture mobile machinery wheel hubs and undercarriage applications.
