The AirTAC Airtac SC40 Standard Cylinder SC40X710 is a genuine double-acting standard air cylinder with a Ø40mm bore and 710mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X710 is a double-acting tie-rod cylinder providing a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 710 mm stroke, this model is well-suited for medium-reach linear tasks where a compact body length is required.
This cylinder features a 16 mm diameter piston rod with an M12x1.25 rod thread and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, effectively decelerating the piston to reduce end-of-stroke impact. The total extended body length is approximately 852 mm, calculated from the 142 mm body length A plus the 710 mm stroke.

Pushes or diverts medium-weight packages on a conveyor line, leveraging the 710 mm stroke for wide-reach transfer between parallel belts.
Provides a long, controlled stroke to eject formed plastic or metal parts from a mold or press tool, using the adjustable cushion to manage cycle speed.
Operates a sliding gate or chute diverter on agricultural processing equipment, where the 628 N push force at standard shop air is sufficient for the panel weight.
For applications needing 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 a shorter, more rigid setup is acceptable, the 32 mm bore SC32 series offers 402 N. For this 710 mm stroke, consider external guide rails or a guided cylinder if the load applies any significant side force, as long, unsupported 16 mm rods are susceptible to bending under lateral loads.
When replacing this cylinder, match five key points: the 40 mm bore, the 710 mm stroke, the PT1/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet.
Quick checklist
At 0.7 MPa operating pressure, the push force is 879 N. The theoretical maximum force at 1.0 MPa is 128 kgf, but the cylinder's rated operating range is 0.15 to 1.0 MPa.
Not directly, as this specific model code lacks the -S suffix for a built-in magnet. To use CMSG or DMSG sensors, order model SC40X710-S. Without the magnet, the standard piston band is not detectable by reed or solid-state switches.
