SPNO
Swing Seal
Advantages and Characteristics
SPNO, also known as reverse SPGO, is suitable for one-way piston rod buffer seals in oil cylinders. It can be used in series to withstand higher pressures.
PTFE slip rings can achieve high linear speeds. By changing the elastomer to FKM, high temperatures up to 180℃ can be reached.
