The AirTAC Airtac SC40 Standard Cylinder SC40X220STC is a genuine double-acting standard air cylinder with a Ø40mm bore and 220mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X220STC is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet (-S) for easy mounting of CMSG/DMSG/EMSG sensors and a centre trunnion mount (TC) with the TCM1 bracket (F-SC40TC) for pivoting applications. The 220 mm stroke is well within the 1200 mm maximum standard stroke for 40 mm bore cylinders.

The 220 mm stroke and pivoting trunnion mount suit conveyor diverter gates, where the cylinder swings to redirect packages or components between lanes.
With 628 N of force at 0.5 MPa and sensor-confirmed position feedback, this cylinder reliably clamps workpieces in CNC fixtures and welding jigs.
The trunnion-mounted design handles the arcing motion of hopper or chute doors on agricultural dosing and sorting equipment, withstanding dusty environments.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa. If you need more force, step up to the 50 mm bore (982 N at 0.5 MPa); for a lighter, more compact solution, the 32 mm bore offers 402 N. The centre trunnion mount allows the cylinder to pivot during operation, ideal for swinging loads.
For a direct replacement, match these five points: 40 mm bore, 220 mm stroke, PT port thread, centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is shorter than ISO 15552 designs, so verify mounting dimensions against your existing setup.
Quick checklist
At 0.5 MPa the theoretical push force is 628 N. At the maximum operating pressure of 0.9 MPa, it reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf, but operation is limited to 1.0 MPa.
No. The SC series is a tie-rod cylinder with a shorter body length (A=142 mm) than a typical ISO 15552 cylinder of the same bore. It is not dimensionally interchangeable. Only use it to replace another AirTAC SC40 tie-rod cylinder with matching stroke, port, mount, and magnet options.
