The AirTAC Airtac SC40 Standard Cylinder SC40X175 is a genuine double-acting standard air cylinder with a Ø40mm bore and 175mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X175 is a double-acting tie-rod cylinder delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 40 mm bore and 175 mm stroke, it suits medium-duty linear actuation where a compact body length is needed.
This model uses a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable pneumatic cushion at each end is 21 mm long, helping to decelerate the piston smoothly. The total extended body length is approximately 317 mm, based on the 142 mm body length A plus the stroke.

The 175 mm stroke and 628 N push force at 0.5 MPa effectively actuates diverter gates on light to medium-duty conveyor lines, directing packages or parts between lanes.
Provides controlled clamping force for CNC jigs and assembly fixtures. The adjustable cushioning protects the workpiece and fixture from impact damage during high-speed cycles.
Suitable for case packing and cartoning machines, pushing products into boxes. The tie-rod design allows for easy maintenance in high-cycle packaging environments.
For a step up in force, the 50 mm bore SC50 series provides 982 N push at 0.5 MPa. If space is tighter and less force is acceptable, the 32 mm bore SC32 offers 402 N at the same pressure. When replacing this cylinder, match five points: 40 mm bore, 175 mm stroke, PT1/4 port thread, basic mount (no accessory), and the absence of a magnet. For strokes of 175 mm, the 16 mm rod is rigid for most inline loads, but any side loading requires an external guide to prevent rod bearing wear and bending.
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. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than a standard ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. It directly replaces another AirTAC SC40 cylinder with the same stroke, port thread, and mounting configuration.
