FAQ What is the primary advantage of FKM material over standard NBR for a shaft seal?FKM (Fluoroelastomer), like the 75 FKM 585 compound used here, offers significantly higher temperature resistance (up to 200 deg C) and superior chemical resistance to oils, fuels, and acids compared to NBR (Nitrile Butadiene Rubber), which is typically limited to around 100-120 deg C. What does the ‘AS’ designation in the DIN standard signify for this seal?The ‘AS’ designation indicates a standard design profile for a radial shaft seal that includes an additional, non-spring-loaded protective lip (dust lip). This lip faces outwards to prevent dust, dirt, and other contaminants from reaching the primary sealing lip, thereby increasing the seal’s service life and reliability. Is this seal suitable for high-pressure applications?Standard radial shaft seals like this BASL model are designed for low-pressure applications, typically up to 0.5 bar (7 psi). For applications with higher pressures, specially designed high-pressure seals or alternative sealing solutions should be considered to prevent seal failure.
