The AirTAC Airtac SC40 Standard Cylinder SC40X225N 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 SC40X225N is a 40 mm bore double-acting pneumatic cylinder with a 225 mm stroke, part of the AirTAC SC tie-rod series. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, making it a capable mid-range actuator for general industrial automation. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the NBR (nitrile) seals offer reliable performance within the standard -20 to +70 °C operating range.
This model uses a PT1/4 port and an M12x1.25 rod thread, with a body length A of 142 mm. The total extended length is approximately 367 mm. With a maximum standard stroke of 1200 mm for the 40 mm bore, this 225 mm unit is well within standard manufacturing limits. It is a genuine AirTAC component, factory-tested to 1.5 MPa proof pressure for dependable service.

Ideal for shifting small to medium components between conveyor lanes or workstations. The 225 mm stroke provides ample reach for lateral transfer mechanisms without excessive cycle time.
Delivers consistent 628 N clamping force at 0.5 MPa for holding workpieces during machining, welding, or assembly. The adjustable cushion reduces impact, preserving fixture alignment.
Operates diverter gates and flippers in logistics and packaging lines. The NBR seals and tie-rod construction handle the repetitive, high-cycle demands of sorting operations.
Choose the SC40 bore for applications needing around 628 N of force at standard plant pressure. If your load requires more thrust, stepping up to the SC50 bore provides 982 N at the same 0.5 MPa. For lighter, more compact needs, the SC32 delivers 402 N. This 225 mm stroke is moderate; for strokes over 300 mm, assess side-loading on the 16 mm rod and consider an external guide or a guided cylinder to prevent rod bearing wear and bending.
When replacing an existing cylinder, match five key points: 40 mm bore, 225 mm stroke, PT1/4 port thread, NBR seal material, and basic (no bracket) mounting. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC or equivalent tie-rod designs of the same bore and stroke.
Quick checklist
At the standard operating pressure of 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, the push force increases to 1130 N. These values are based on the 40 mm bore and 16 mm rod diameter.
No. The SC40X225N is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston can drift or the load may drop. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod lock.
