The AirTAC Airtac SC32 Standard Cylinder SC32X125STC is a genuine double-acting standard air cylinder with a Ø32mm bore and 125mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X125STC is a double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa and up to 724 N at the 0.9 MPa maximum operating pressure. With a 12 mm piston rod and a 125 mm stroke, this model is well-suited for light clamping, sorting, and pick-and-place tasks where a compact tie-rod design is preferred.
This variant includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, and ships with the TC centre trunnion mount (F-SC32TC) plus the TCM1 bracket for pivoting actuation. The 21 mm adjustable air cushion at each end helps decelerate the piston smoothly, reducing end-of-stroke impact in fast-cycling applications.

The 125 mm stroke and 402 N push force at 0.5 MPa reliably actuate diverter gates on compact conveyor lines, directing lightweight packages or components.
With a built-in magnet for sensor confirmation, this cylinder provides consistent 724 N clamping force at 0.9 MPa for holding small parts during adhesive curing or ultrasonic welding.
The centre trunnion mount allows the cylinder to pivot as it strokes, making it ideal for operating levers, dampers, or tensioning arms on packaging machinery.
Choose the SC32 bore for light-duty tasks needing up to 402 N at 0.5 MPa. If your load requires more force, step up to the SC40, which provides 628 N at the same pressure. For this 125 mm stroke, rod bending is not a primary concern, but always avoid direct side loads on the 12 mm rod.
When replacing an existing cylinder, match five points: 32 mm bore, 125 mm stroke, PT1/8 port thread, TC centre-trunnion mounting with the F-SC32TC bracket, and the built-in magnet for sensor compatibility. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.7 MPa operating pressure, the push force is 563 N and the pull force is 483 N (calculated from the 345 N pull at 0.5 MPa). The maximum push force at 0.9 MPa is 724 N.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp compatible CMSG, DMSG, or EMSG reed or solid-state sensors directly onto the barrel to detect end-of-stroke position.
