Piston seal KGD 140x115x25,4/44,4

The KGD 140x115x25,4/44,4 piston seal is a double-acting piston ring with guide rings, designed for use in hydraulic cylinders. The design consists of a rubber sealing element with low compression set, two anti-extrusion rings and guide rings, which stabilise the piston movement and absorb radial loads. The profile provides effective control of the working medium and even distribution of pressure. Technical data: Outer diameter (D): 140 mm Inner diameter (d): 115 mm Seal height (L): 25,4 mm Overall dimension (M): 44,4 mm Size in inches: 5.51 x 4.53 x 1.00 / 1.75 (Dxdxheight/overall dimension) Working pressure: up to 400 bar Speed: up to 0,5 m/s Medium: mineral-based hydraulic oils
