The AirTAC Airtac SC40 Standard Cylinder SC40X230 is a genuine double-acting standard air cylinder with a Ø40mm bore and 230mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X230 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at the 0.9 MPa maximum operating pressure). Its 16 mm diameter piston rod and 21 mm adjustable air cushion make it a dependable workhorse for medium-duty linear actuation across a 230 mm stroke.
This model uses the standard TPU/NBR seal package for a -20 to +70 °C operating range and PT1/4 threaded ports. With a body length A of 142 mm, the total extended length is approximately 372 mm. It is a genuine AirTAC SC series unit, engineered for reliable cycling in industrial automation.

The 628 N push force at 0.5 MPa is well-suited for diverting or stopping medium-weight packages on conveyor lines, providing a 230 mm stroke for lateral product transfer.
Provides consistent, controlled force for holding parts during welding, gluing, or machining operations. The adjustable cushion ensures smooth end-of-stroke deceleration, protecting the fixture.
Ideal for operating small sorting gates or chute diverters in logistics hubs. The 16 mm rod and tie-rod construction offer rigidity for frequent, repetitive cycling.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. If space is tight and the load is lighter, the 32 mm bore SC32 offers 402 N at the same pressure. The SC40X230 is a standard-stroke model within the 40 mm bore's 1200 mm maximum.
When replacing an existing cylinder, match these five points exactly: 40 mm bore, 230 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the absence of a built-in magnet. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile, so it is not a drop-in replacement for that standard.
Quick checklist
At the standard 0.5 MPa operating pressure, 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. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts or overall lengths. It is a direct replacement only for another AirTAC SC40 tie-rod cylinder with matching bore, stroke, port thread, and mounting.
