The AirTAC Airtac SC40 Standard Cylinder SC40X200S is a genuine double-acting standard air cylinder with a Ø40mm bore and 200mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X200S is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 40 mm bore and 200 mm stroke suit medium-duty linear tasks where space is constrained, and the built-in magnet allows direct mounting of CMSG or DMSG sensors for reliable end-of-stroke detection.
This tie-rod cylinder uses a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable air cushion at each end decelerates the piston over 21 mm to reduce impact noise. The body length A is 142 mm, giving a total extended length of approximately 342 mm.

Operates a diverter gate on a conveyor line, using the 200 mm stroke to redirect cartons. The -S magnet triggers a CMSG sensor to confirm gate position for the line controller.
Provides 628 N of clamping force at standard line pressure for a CNC drilling jig. The sensor-ready barrel simplifies integration with the machine's safety interlock circuit.
Extends a sampling probe into a process stream with a clean 200 mm linear motion. The adjustable cushion allows fine-tuning of the probe's deceleration to prevent fluid disturbance.
Choose the SC40 bore when your application needs between 528 N (pull at 0.5 MPa) and 1130 N (push at 0.9 MPa). If you require higher force, step up to the SC50, which provides 982 N push at 0.5 MPa. For a smaller footprint, the SC32 delivers 402 N push at 0.5 MPa. At 200 mm stroke, side-loading is minimal, but always align the load with the rod axis.
For a direct replacement, match five key points: 40 mm bore, 200 mm stroke, PT1/4 ports, the built-in magnet (-S suffix), and the basic mounting style. The SC series is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC cylinder of the same configuration.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a magnet is embedded in the piston, designed for AirTAC's CMSG (reed) and DMSG/EMSG (solid-state) sensors. Clamp the sensor directly onto the barrel tie-rod tube to detect piston position without additional brackets.
