The AirTAC Airtac SC40 Standard Cylinder SC40X2000S is a genuine double-acting standard air cylinder with a Ø40mm bore and 2000mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X2000S is a double-acting single-rod tie-rod cylinder with a 40 mm bore and an extended 2000 mm stroke. This non-standard stroke length exceeds the standard maximum of 1200 mm for the 40 mm bore, making it a made-to-order configuration for applications requiring exceptional linear reach. The built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise, non-contact position feedback.
At 0.5 MPa, the 16 mm diameter rod delivers a push force of 628 N and a pull force of 528 N, scaling to 1130 N of push thrust at the maximum operating pressure of 0.9 MPa. The cylinder features an adjustable pneumatic cushion (21 mm length) to decelerate the piston smoothly at both ends of the stroke. With a body length A of 142 mm, the total extended length is approximately 2142 mm. The rod end thread is M12x1.25, and the standard PT1/4 port provides the air connection.

The 2000 mm stroke is ideal for pushing products across wide conveyor sections or diverting items onto parallel lines, with sensor feedback confirming full extension and retraction.
Extends a spray nozzle assembly across a wide treatment area in agricultural or industrial coating machinery. The magnet allows end-of-travel sensing for cycle control.
Used in a vertically guided lifting frame to raise or lower large panels, doors, or hatches. The adjustable cushioning prevents hard stops at the 2-meter stroke limits.
For a 40 mm bore, the SC40X2000S provides 628 N of push force at 0.5 MPa. If your application requires higher force, stepping up to the 50 mm bore (SC50) offers 982 N at the same pressure. For lower force requirements, the 32 mm bore (SC32) delivers 402 N. Always confirm that the load, speed, and available air pressure align with the cylinder's force output.
At a 2000 mm stroke, the long, unsupported 16 mm rod is highly susceptible to bending under side loads. An external linear guide or a guided cylinder configuration is strongly recommended to protect the rod bearing and piston seals from premature wear. For replacement, match five key specifications: 40 mm bore, 2000 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic mounting style.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder generates 628 N of push force and 528 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
No, the maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm, so this 2000 mm stroke is a non-standard, made-to-order item. To prevent the long 16 mm rod from bending under side load, you must use an external linear guide or a guided cylinder assembly.
