DSNU-40-30-P-A – Compact Power with Durable Construction
The DSNU-40-30-P-A is a double-acting round pneumatic cylinder featuring a 40 mm piston diameter and a 30 mm stroke, making it ideal for short-stroke linear motion tasks that demand significant force. This model uses elastic cushioning rings at both ends to minimize impact and reduce wear, ensuring a longer service life. It delivers a theoretical advance force of 752.9 N and a return force of 633.3 N at 6 bar pressure. The piston rod is threaded (M12x1.25) and made of high-alloy steel, while the cylinder barrel uses stainless steel to resist corrosion. It supports G1/4 pneumatic connections, complies with RoHS standards, and allows proximity switch mounting for position feedback—ideal for modern automation systems.
Applications of DSNU-12-70-P-A – For Tight Spaces and Light Actuation Tasks
The DSNU-12-70-P-A cylinder is widely used in compact automation setups where space and precision matter. Its slim profile and 70 mm stroke make it suitable for light-duty pushing or lifting operations—such as moving guide pins, triggering limit stops, or ejecting finished components. In assembly jigs, test benches, and lab automation systems, this cylinder provides clean, linear movement with low air consumption. Engineers value its easy installation and integration with sensors, while students can learn key pneumatic principles from its transparent and functional design. Its small size hides big utility—making it a smart component in efficient, modern machines.
