The double-acting piston seal type SPGA byWYS is a specialized heavy duty piston sealing element, whose main function is to retain oil pressure. It consists of two components: an outer ring (slide ring) made of reinforced polyamide (PA, Nylon), and an inner ring with a circular cross-section made of nitrile rubber NBR 70 Shore A. The outer ring provides exceptional resistance to wear, deformation and extrusion in large clearances and has a specific cut to facilitate installation, while the inner O-ring provides constant radial compression and pressure maintenance.
Main features:
- High mechanical strength: The nylon element allows operation with larger assembly and operating clearances between the rod and the cylinder, without the risk of damage to the seal
- No "Stick-Slip" effect: The profile ensures low friction at start-up and smooth movement even at very low speeds (from 0.008 m/s)
- Excellent static and dynamic sealing: The O-ring prevents internal leakage in the cylinder, even during prolonged periods of pressure
SPGA is suitable for installation in hydraulic cylinders of construction and mining machines, and is extremely popular as an alternative or original equipment in Caterpillar.
