The AirTAC SC40 Standard Cylinder SC40X385S is a genuine double-acting standard air cylinder with a Ø40mm bore and 385mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X385S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 385 mm stroke. It generates 628 N of push force and 528 N of pull force when operated at 0.5 MPa, making it a solid choice for medium-duty linear tasks. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors along the barrel for precise, non-contact position sensing.
This model features a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 ports. The adjustable air cushion at each end, with a cushion length of 21 mm, decelerates the piston smoothly to reduce end-of-stroke impact. With a body length of 142 mm, the total extended length is approximately 527 mm. The standard operating temperature range is -20 to +70 °C with its TPU seals.

The built-in magnet and 385 mm stroke enable precise, sensor-monitored ejection of finished parts from an assembly fixture, confirming full extension and retraction for reliable cycle counting.
With 628 N of push force, this cylinder reliably actuates a diverter gate on a conveyor line. The magnetic piston allows end-of-stroke sensors to verify gate position for automated sortation control.
Applies consistent, controlled force to compress and square-up cartons before strapping. The 385 mm stroke accommodates a deep compression chamber, while sensors confirm the plate's home and advanced positions.
For applications requiring a bit more force, stepping up to the 50 mm bore SC50 series provides 982 N of push force at the same 0.5 MPa pressure. If space is a constraint, the 32 mm bore SC32 offers 402 N. At a 385 mm stroke, the 16 mm rod is well-supported, but always ensure the load is guided to prevent side-loading, which can bend the rod or damage the bearing. For replacement, match the 40 mm bore, 385 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting style to ensure a direct fit for another AirTAC SC tie-rod cylinder.
Quick checklist
At the standard operating pressure of 0.7 MPa, the cylinder produces a theoretical push force of 879 N. The maximum push force at 0.9 MPa is 1130 N. Pull force is lower due to the rod area; at 0.5 MPa, the pull force is 528 N.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke. It is a direct dimensional match only for another AirTAC SC tie-rod cylinder with the same bore, stroke, port thread, and magnet option.
