The AirTAC Airtac SC40 Standard Cylinder SC40X1120S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1120mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1120S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a 16 mm diameter piston rod, it is well-suited for long-stroke material transfer and clamping applications where a compact footprint is required.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG sensors to mount directly on the barrel for reliable end-of-stroke detection. The 1120 mm stroke is within the 1200 mm maximum standard stroke for the 40 mm bore. The cylinder uses a PT1/4 port and an M12x1.25 rod thread, with a 21 mm adjustable air cushion at each end to decelerate the load smoothly.

Moves components 1120 mm between stations on automated assembly lines, with sensor feedback confirming full extension and retraction.
Applies consistent clamping force in woodworking or light metalworking fixtures, using the built-in magnet for cycle verification.
Operates diverter gates on conveyor systems, where the long stroke and magnetic piston sensing ensure reliable product routing.
For applications needing more force, stepping up to the 50 mm bore (SC50) provides 982 N of push at 0.5 MPa. For a shorter, more rigid assembly, consider the 32 mm bore. When replacing an existing cylinder, match the 40 mm bore, 1120 mm stroke, PT1/4 port thread, and ensure the replacement also has the -S magnet option for sensor compatibility. At this stroke length, the 16 mm rod is susceptible to bending under side loads; always guide the load externally or use a guided cylinder if off-axis forces are present.
Quick checklist
At 0.5 MPa (5 bar), the cylinder provides 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Match the 40 mm bore, 1120 mm stroke, PT1/4 pneumatic ports, and the -S suffix for the built-in magnet. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is only guaranteed with another AirTAC SC series cylinder of the same specifications.
