DSH Seals’ SPNO Standard compact seal for wide application. We are designed according to NOK’s SPNO series standard. This filler has low frictional resistance, eliminates stick-slip and ensures high wear resistance. It is a standard combination seal for a variety of operations. Applications: engineering machinery, presses, agricultural machinery, lifts, industrial enquipment, injection molding machines.
SPNO type hydraulic seal is a relatively soft, non-metallic ring that is captured in a groove or fixed in a combination of rings to form a seal assembly to prevent or separate fluids in reciprocating applications. Hydraulic sealing is essential in machinery. Their use is critical to providing a way to convert fluid dynamics into linear motion.
