CDQ2B20-10DCZ Applications
A 20 mm bore CQ2 with a 10 mm stroke, giving noticeably more thrust than the 16 mm units in a body that is still very short front-to-back. It suits clamping, pressing, stopping and part ejection on assembly and packaging machinery. The C option adds a rubber bumper at each end of stroke, cushioning the impact when the cylinder is cycled fast or drives a heavier tool - useful for reducing noise and extending life on high-cycle stations. The built-in magnet supports groove-mounted auto switches.
