The AirTAC Airtac SC40 Standard Cylinder SC40X180S is a genuine double-acting standard air cylinder with a Ø40mm bore and 180mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X180 is a double-acting tie-rod cylinder delivering 628 N of push force and 528 N of pull force when operated at 0.5 MPa. With a 40 mm bore and 180 mm stroke, this model uses a 16 mm diameter piston rod and PT1/4 ports, making it a capable mid-range actuator for general industrial automation.
At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The cylinder body length (A) is 142 mm, giving a total extended length of approximately 322 mm. It includes an adjustable air cushion (21 mm length) to decelerate the piston smoothly at end-of-stroke, reducing impact and noise.

Actuates diverter gates and stops on light to medium-duty conveyor lines, where the 628 N push force at 0.5 MPa reliably moves product guides.
Provides consistent clamping pressure for assembly jigs and welding fixtures, with the 16 mm rod offering good rigidity for the 180 mm stroke.
Drives compact pressing or stamping actions in packaging machinery, benefiting from the adjustable cushion to reduce wear during high-cycle operation.
For applications requiring slightly more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N of push force at 0.5 MPa. If a shorter, more compact solution is acceptable, the 32 mm bore SC32 offers 402 N at the same pressure. Always ensure the load is guided externally if side forces are present, as the rod bearing is not designed to support lateral loads.
When replacing an existing cylinder, match five key points: bore (40 mm), stroke (180 mm), port thread (PT1/4), mounting accessory (basic), and the presence of a magnet (this model has none). The SC series is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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, 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 shorter in overall length than a standard ISO 15552 cylinder. It is a direct replacement only for another AirTAC SC40 cylinder with the same bore, stroke, PT port thread, and basic mounting configuration.
