Description
SPNO Cylinder Rod Seals are composite rod seals that can be used in a variety of applications. We are built to the SPNO series specification by NOK. Low frictional resistance, no stick-slip, and good wear resistance are all advantages of this filler. It's a common combination seal that can be used for a variety of tasks. Engineering machinery, presses, agricultural machinery, elevators, industrial equipment, and injection molding machines can all benefit from the Cylinder Rod Seals SPNO.
In reciprocating applications, an SPNO type hydraulic seal is a relatively soft, non-metallic ring that is trapped in a groove or secured in a combination of rings to form a seal assembly to prevent or separate fluids. In equipment, hydraulic sealing is critical. Their application is important for converting fluid dynamics into linear motion.
