FPM Rotary Shaft Seal 180x215x15 AO Double Lip FKM

Heavy Duty Rotary Shaft Seal for Large Industrial Equipment

The FPM Rotary Shaft Seal 180x215x15 AO is a premium radial shaft seal engineered for large rotating shafts operating in demanding industrial environments. Manufactured from high-performance FPM (FKM, Viton) fluoroelastomer, it provides outstanding resistance to high temperatures, mineral oils, synthetic lubricants, fuels and aggressive chemicals. The AO profile incorporates a spring-loaded primary sealing lip together with an additional dust lip, delivering reliable lubricant retention while preventing contamination from entering the sealing area. With dimensions of 180x215x15 mm, this heavy-duty shaft seal is widely used in industrial gearboxes, pumps, mining equipment, steel processing machinery, marine drives, power transmission systems and heavy production equipment where long service life and dependable sealing performance are essential. FPM compounds are suitable for continuous operation at temperatures up to approximately +200 C.
