The AirTAC Airtac SC32 Standard Cylinder SC32X120S is a genuine double-acting standard air cylinder with a Ø32mm bore and 120mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X120S is a compact double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). Its 12 mm diameter piston rod and 21 mm adjustable air cushion make it well-suited for light automation tasks where smooth end-of-stroke deceleration is required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for contactless position sensing. The 120 mm stroke falls within the standard range for the 32 mm bore, ensuring quick availability without special order lead times.

The 120 mm stroke and sensor-ready magnet make this cylinder ideal for actuating diverter gates on small-part conveyor systems, where end-of-stroke confirmation is required for cycle counting.
Compact footprint and clean double-acting operation suit test-tube handling or microplate positioning. The adjustable cushion protects delicate samples from jarring at stroke end.
Delivers consistent 402 N push force for pressing labels onto packaging. The built-in magnet enables precise stroke-end sensing to synchronize with the label feed mechanism.
Choose the SC32 bore for push forces up to 402 N at 0.5 MPa; if your application demands higher force, step up to the SC40 bore which provides 628 N at the same pressure. For strokes of 300 mm or longer on this 12 mm rod, evaluate side-load conditions carefully—an external guide or guided cylinder is recommended to prevent rod bending.
When replacing an existing cylinder, match five points: 32 mm bore, 120 mm stroke, PT1/8 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting configuration. This ensures a direct drop-in fit with no re-engineering of end connections or sensor layouts.
Quick checklist
At 0.5 MPa the cylinder pushes with 402 N and pulls with 345 N. At the maximum operating pressure of 0.9 MPa, 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, so CMSG, DMSG, or EMSG sensors clamp directly onto the barrel without any modification. This is the standard sensor-ready configuration for the SC series.
