Piston seal K17 100x84,5x6,3

K17 piston seal, dimensions 100×84,5×6,3 mm. This is a seal for hydraulic cylinders, used in applications requiring resistance to high pressures and working speeds. The K17 design consists of a sealing ring made of PTFE and an NBR energising O-ring, which provides the appropriate preload and stable operation in the groove. Thanks to its low coefficient of friction, this seal minimises wear and is suitable for dynamic operating conditions. Design features: piston profile for hydraulic power applications, PTFE sealing ring supported by an NBR O-ring, very low friction and low tendency to stick-slip, resistant to high pressures and working speeds. Technical data (according to the catalogue): Inner diameter d: 84,5 mm (≈ 3.33 inches) Outer diameter D: 100 mm (≈ 3.94 inches) Height H: 6,3 mm (≈ 0.25 inches) Material: PTFE (sealing ring) + NBR (energising O-ring) Maximum pressure: up to 400 bar Working speed: up to 5 m/s
