The AirTAC Airtac SC32 Standard Cylinder SC32X20S is a genuine double-acting standard air cylinder with a Ø32mm bore and 20mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X20S is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa) from a 32 mm bore. Its short 20 mm stroke suits precise, short-throw clamping, ejecting, or sorting tasks where space is tight and cycle rates are high.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to mount directly on the barrel for reliable end-of-stroke detection. The 12 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration, while the PT1/8 port and M10x1.25 rod thread keep connections standard.

The 20 mm stroke and 402 N push force at 0.5 MPa are ideal for ejecting small parts from fixtures or dies in automated assembly cells, where sensor confirmation of rod position prevents machine crashes.
With a speed range of 30-800 mm/s and built-in magnet for end-of-stroke sensing, this cylinder actuates diverter gates on small-package conveyor lines, providing fast, confirmed sorting cycles.
Delivers 724 N at 0.9 MPa for light-duty clamping of workpieces during drilling or welding. The adjustable cushion protects the end cap from impact at high cycle rates.
Choose the SC32X20S when your application needs a compact 32 mm bore with sensor-ready position feedback. If you require more force, step up to the SC40 series (628 N push at 0.5 MPa). For strokes longer than 20 mm, standard strokes up to 500 mm are available in this bore.
To match an existing cylinder, verify five points: 32 mm bore, 20 mm stroke, PT1/8 port thread, the built-in magnet (-S), and the basic (no bracket) mounting. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa the push force is 563 N and the pull force is 483 N (based on the 32 mm bore and 12 mm rod). The maximum push force at 0.9 MPa operating pressure is 724 N.
Yes. The -S suffix indicates a built-in magnet, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without external brackets.
