PSD-100 | Packing

The SAKAGAMI PSD-Packings (Piston Packings) are high-performance pneumatic seals designed for double-acting piston applications where smooth motion, low friction, and long service life are critical. Manufactured using advanced elastomer materials, PSD-Packings offer superior sealing efficiency compared to conventional O-rings, while eliminating common issues such as twisting and rolling during operation.

Engineered for compact groove designs, PSD piston packings ensure stable performance under repeated reciprocating motion. Their optimized profile delivers excellent friction characteristics, reduced wear, and reliable sealing even at higher speeds. These packings are widely used in industrial pneumatic cylinders, automation equipment, and precision machinery where consistent sealing and durability are essential.

Available in standard NBR (RN729) for general-purpose use and FKM (RF704) for high-temperature applications, PSD-Packings provide flexibility across a wide range of operating environments. The design also allows compatibility with wear rings, improving guidance and extending cylinder life.
