The AirTAC Airtac SC40 Standard Cylinder SC40X225 is a genuine double-acting standard air cylinder with a Ø40mm bore and 225mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X225 is a double-acting tie-rod cylinder with a 40 mm bore and 225 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range linear tasks.
With a compact body length A of 142 mm, this cylinder fits into machine frames where space is limited. The standard PT1/4 port and M12x1.25 rod thread simplify pneumatic connections and tooling attachment for factory automation setups.

The 225 mm stroke and 628 N push force at 0.5 MPa make this cylinder suitable for stopping or diverting light packages on conveyor lines.
Delivers consistent clamping force up to 1130 N at 0.9 MPa for holding workpieces during drilling, welding, or assembly operations.
Operates gates or flaps on hoppers and chutes, where the 21 mm cushion absorbs impact energy at the end of the 225 mm travel.
Choose the SC40 bore for light pressing, clamping, and sorting operations requiring around 628 N at standard line pressure. If your load exceeds this, stepping up to the SC50 bore provides 982 N at the same 0.5 MPa. For strokes above 300 mm on this 16 mm rod, evaluate side-load conditions—an external linear guide or a guided cylinder may be needed to protect the rod bearing from bending moments.
When replacing an existing unit, match five points: bore (40 mm), stroke (225 mm), port thread (PT1/4), mounting accessory (basic, or add an F-SC40 mount bracket if needed), and magnet option (this model has no built-in magnet).
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke, so it is not dimensionally interchangeable. Only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port, and mounting.
