Stainless Steel Tube Small Bore Hydraulic Cylinder for 7 MPa Series CHN o20, o25, o32, o40 Cushion valve Aluminum cover Equipped with cushion mechanism . A cushion seal system mechanism is now a standard feature. . Cushion valves are enhanced with a non-slip retaining mechanism. . The cushion valve is a discreet type valve that does not protrude from the cover face. Cushion valve Retaining ring Stainless steel tube Auto switch Lightweight Built-in magnet Model Weight (kg) Basic type with a 100 mm stroke Reduced cross sectional area �ｮ48 mm �ｮ63 mm CHN o40 CH2 o40 Series Nominal pressure Bore size (mm) Mounting bracket Series Variations Auto Switches Band mounting type Reed type Solid state type Basic style Axial foot style Rod flange style Head flange style Single clevis style 20 25 32 40 CHN 7.0 MPa CHNB20-100 CHNB25-100 CHNB32-100 CHNB40-100 0.51 0.63 0.89 1.51 All cylinders come with a built-in magnet as a standard feature. This makes possible the mounting of an auto switch for piston position sensing even after the cylinder has been installed. Using aluminum alloy for both the rod cover and head cover reduces overall weight. When compared to the same size tie-rod cylinder, the cross sectional area of our Series CHN cylinder projects less than 45%, thereby attaining better space savings. 1316
