CM2B40-25Z Applications

At 40mm bore this is the largest CM2-Z size, giving the highest thrust in the series for pressing, clamping, stamping and heavy pushing tasks; the short 25mm stroke concentrates that force over a small travel, typical of clamp and short-press stations. The basic double-side bossed mount is fastened with a mounting nut at either end. Rubber bumper cushioning is fitted, and the cylinder has no built-in magnet, so it operates without auto switch position sensing.
