The AirTAC Airtac SC32 Standard Cylinder SC32X1250STC is a genuine double-acting standard air cylinder with a Ø32mm bore and 1250mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X1250STC is a double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa (724 N at the 0.9 MPa maximum operating pressure) from its 32 mm bore. This model features a non-standard 1250 mm stroke, which exceeds the 1000 mm maximum standard stroke for this bore, making it a made-to-order configuration for long-reach applications.
Equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC, supplied with TCM1 bracket F-SC32TC), this cylinder is ready for pivoting actuation. It uses a 12 mm diameter piston rod with an M10x1.25 thread, PT1/8 ports, and an adjustable air cushion length of 21 mm to decelerate the load smoothly.

The 1250 mm stroke extends across wide conveyor gaps to push or lift products between lines, with sensor confirmation from the built-in magnet.
Pivots a long sorting gate or diverter arm smoothly on its centre trunnion mount, using adjustable cushioning to handle the high inertia of the extended stroke.
Provides the extended reach needed for lifting or positioning lightweight tooling on vertical masts in packaging machinery, where space for a larger bore is limited.
Select the SC32 when your application requires up to 724 N of force at 0.9 MPa. If you need more power, step up to the SC40, which provides 628 N at 0.5 MPa. For strokes of this length (1250 mm), the slender 12 mm rod is susceptible to bending under side loads; always use an external guide or a guided cylinder to prevent rod bearing damage and ensure linear motion. To match this cylinder for replacement, verify five points: 32 mm bore, 1250 mm stroke, PT1/8 port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet (-S).
Quick checklist
At the maximum operating pressure of 0.9 MPa, the cylinder produces a theoretical push force of 724 N. At the standard 0.5 MPa pressure, the push force is 402 N and the pull force on the return stroke is 345 N.
A 12 mm rod extended to 1250 mm is highly vulnerable to buckling and side-load damage. You must guide the load externally with a linear rail or rod guide, or use an AirTAC guided cylinder assembly. Never allow the rod to push an unguided mass over this distance.
