The AirTAC Airtac SC32 Standard Cylinder SC32X550STC is a genuine double-acting standard air cylinder with a Ø32mm bore and 550mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X550STC is a double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa. With a 12 mm piston rod and a 550 mm stroke, this model extends beyond the standard 1000 mm maximum for the 32 bore, making it a made-to-order configuration for applications needing an extra-long reach in a compact 32 mm body profile.
This specific unit is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) including the TCM1 bracket (F-SC32TC) for controlled pivoting motion. The 21 mm adjustable air cushion at each end helps decelerate the piston smoothly, protecting the end caps during high-cycle operation.

The 550 mm stroke on a 32 mm bore pushes lightweight components across wide conveyor gaps or into secondary stations where a compact body is needed alongside the conveyor frame.
The built-in magnet allows CMSG/DMSG sensors to confirm end-of-stroke position, making this cylinder suitable for pick-and-place units where the controller must verify full extension and retraction.
With the TC centre trunnion mount, this cylinder can pivot to operate a small gate or clamp, absorbing the arc motion while the 21 mm cushion softens the stop at each end of the 550 mm travel.
Choose the SC32 when your application requires a compact footprint with moderate force—the 32 mm bore provides 402 N at 0.5 MPa. If you need more push force, step up to the SC40 which delivers 628 N at the same pressure. For this 550 mm stroke, which is longer than the standard range, ensure the load is guided externally; a 12 mm rod extended over half a metre is susceptible to bending under side loads, so pairing this cylinder with a linear guide or using a guided cylinder is strongly recommended.
For a correct drop-in replacement, match five key points: the 32 mm bore, the 550 mm stroke, the PT1/8 port thread, the centre trunnion mounting accessory (F-SC32TC), and the built-in magnet for sensor compatibility. This tie-rod cylinder is shorter than an ISO 15552 unit and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.7 MPa operating pressure, the 32 mm bore double-acting cylinder produces a theoretical push force of 563 N. The pull force on the retract stroke is 345 N at 0.5 MPa, accounting for the area reduction of the 12 mm piston rod.
It is not recommended. The 12 mm diameter rod is slender for a 550 mm stroke. Applying any side load or moving an unguided mass at the rod end can cause the rod to bend or the bearing to wear prematurely. Always use an external guide rail or rod band to absorb transverse forces.
