The AirTAC Airtac SC32 Standard Cylinder SC32X425S is a genuine double-acting standard air cylinder with a Ø32mm bore and 425mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X425S is a double-acting single-rod tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure). Its 425 mm stroke makes it a solid choice for medium-reach material-handling or assembly tasks where a compact body is needed—the body length A is just 140 mm.
The built-in magnet (suffix -S) allows CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for non-contact position sensing. With a 12 mm rod, PT1/8 ports, and an adjustable air cushion of 21 mm, this model offers precise end-of-stroke deceleration without adding external shock absorbers.

The 425 mm stroke and 402 N push force at 0.5 MPa suit conveyor diverters and part-transfer stations where a moderate reach and quick cycle times are required.
Ideal for pushing components into fixtures on automated assembly lines. The built-in magnet provides sensor feedback to confirm full extension and retraction.
Actuates sorting gates in logistics hubs. The adjustable cushion allows for quiet, controlled stopping of the 12 mm rod, even at the 30-800 mm/s speed range.
For applications needing more force, stepping up to the 40 mm bore SC40 series provides 628 N push at 0.5 MPa. If your load is lighter and speed is the priority, staying with the 32 mm bore keeps the cylinder compact and responsive. The 425 mm stroke is within the 1000 mm maximum standard stroke for this bore.
When replacing an existing cylinder, match five points: 32 mm bore, 425 mm stroke, PT1/8 port thread, the basic mounting style, and the -S magnet option for sensor compatibility. For strokes over 300 mm, ensure the rod is not subjected to significant side load; use an external guide or a guided cylinder if lateral forces are present to prevent rod bending and premature seal wear.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder provides 402 N extending (push) and 345 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 724 N. The theoretical maximum force at 1.0 MPa is 82 kgf.
Yes. The ‘-S’ suffix in the model code SC32X425S indicates a built-in magnet. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel for reliable, non-contact end-of-stroke position sensing.
