The AirTAC Airtac SC40 Standard Cylinder SC40X40S is a genuine double-acting standard air cylinder with a Ø40mm bore and 40mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X40S is a compact double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, ideal for short-stroke clamping and positioning tasks. Its 40 mm stroke suits space-constrained automation where a quick, repeatable linear motion is needed.
This model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for precise end-of-stroke or mid-stroke position feedback. The 16 mm diameter rod and PT1/4 port thread ensure reliable pneumatic performance.

Short-stroke fixture clamping in CNC or assembly jigs where sensor confirmation of clamp position is required for cycle start.
Actuating a small diverter gate on a conveyor line, using the magnetic piston to trigger a DMSG sensor for gate open/closed status.
Precise 40 mm reagent dispensing or vial handling in benchtop analyzers, leveraging the clean, sensor-ready design.
With 628 N push at 0.5 MPa, the SC40X40S handles light assembly and sorting. If you need more force, stepping up to the 50 mm bore provides 982 N at the same pressure. For strokes over 100 mm in this bore, consider an external guide if side loads are present, though the short 40 mm stroke here is inherently rigid. When replacing, match bore, 40 mm stroke, PT1/4 port, and the -S magnet option.
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.
Yes, the -S suffix denotes a built-in magnet. You can directly mount AirTAC CMSG, DMSG, or EMSG sensors on the barrel to detect piston position without external brackets.
