Shaft seal, Simmerring, NBR & PTFE (Teflon inner lip), 25x38x7mm, e.g., for crankshaft (930675)

Shaft seal, Simmerring, Type AS, made of NBR & PTFE (Teflon inner lip), 25x38x7mm (930675) e.g., suitable for Rotax MAX crankshaft Application Radial shaft seal ring DIN 3760 - Type AS with additional sealing lip - Material NBR & PTFE Used to seal low-viscosity fluids on rotating machine parts Type AS - rubber-elastic outer jacket with additional dust-sealing lip The use of the PTFE sealing lip minimizes power loss (friction loss). The seal is suitable for sliding speeds up to 20 m/s and pressures up to 30 bar; the operating temperature range is -30 °C to +200 °C Description Consists essentially of a rubber component, a stiffening plate, and a torsion spring made of spring steel Type AS consists of a rubber-elastic outer jacket with an additional dust lip to protect against dirt and corrosion Good compensation for high surface roughness or thermal expansion Prevents housing damage when replacing the shaft seal Technical Data Material - NBR 72° Shore A & Sealing lip made of PTFE compound (guarantees good running characteristics) Temperature range - -30°C to 200°C  Max. operating speed: 20 m/s
