The AirTAC Airtac SC32 Standard Cylinder SC32X140S is a genuine double-acting standard air cylinder with a Ø32mm bore and 140mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X140S is a double-acting AirTAC SC tie-rod cylinder with a 32 mm bore and 140 mm stroke, delivering a push force of 402 N at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa. Its 12 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration for light to medium automation tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for reliable end-of-stroke detection without external brackets. The compact body length A of 140 mm plus the 140 mm stroke results in a total extended length of approximately 280 mm, making it a space-efficient choice for sensor-equipped pick-and-place or sorting stations.

The built-in magnet allows CMSG/DMSG sensors to confirm cylinder position at each stroke end, ideal for small-part sorting gates and diverters requiring closed-loop control.
With 402 N of push force at 0.5 MPa, this cylinder efficiently pushes lightweight cartons or trays off a conveyor line, with cushioning to protect the product.
The compact 32 mm bore and 140 mm stroke suit benchtop fluid handling or test-tube capping mechanisms, where magnetic piston sensing confirms each cycle step.
Choose the SC32 bore when your application requires up to 402 N of push force at standard 0.5 MPa supply. If you need more force, stepping up to the SC40 bore provides 628 N at the same pressure. For replacement, match five key points: 32 mm bore, 140 mm stroke, PT1/8 port thread, the built-in magnet (-S), and basic mounting style. The 140 mm stroke is well within the 1000 mm maximum standard stroke for the 32 mm bore, ensuring standard lead times.
At this stroke length, side loading should be avoided. Ensure the load is guided externally and aligned axially with the rod to prevent bending stress on the 12 mm rod and premature bearing wear.
Quick checklist
At 0.5 MPa the push force is 402 N, and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can directly clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel tie-rods to detect piston position without any additional mounting hardware.
