The AirTAC Airtac SC40 Standard Cylinder SC40X1600S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1600mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1600 is a double-acting single-rod pneumatic cylinder with a 40 mm bore and an extended 1600 mm stroke, which exceeds the standard maximum of 1200 mm for this bore size, making it a non-standard, made-to-order configuration. It generates a theoretical push force of 628 N at 0.5 MPa and up to 1130 N at its maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This tie-rod cylinder features an adjustable pneumatic cushion at both ends with a 21 mm cushion length to decelerate the piston smoothly. The body length A is 142 mm, resulting in a total extended length of approximately 1742 mm. It uses a PT1/4 port and an M12x1.25 rod thread, operating on filtered air within a standard temperature range of -20 to +70 °C.

Ideal for pushing or pulling lightweight components across a wide conveyor gap where a long, non-standard stroke is essential for bridging the distance.
Provides the extended linear motion needed for applying a continuous bead of adhesive or sealant along a lengthy workpiece in a semi-automated fixture.
Operates a diverter gate or stop at the far end of a packaging line chute, where the actuator must be mounted away from the product flow.
For applications requiring slightly less force, consider stepping down to a 32 mm bore, which provides 402 N of push force at 0.5 MPa. If more force is needed, the 50 mm bore offers a significant jump to 982 N at the same pressure. Always ensure the bore and stroke match your existing unit precisely.
Given the exceptionally long 1600 mm stroke on a 16 mm rod, this cylinder is highly susceptible to rod buckling and bending under side loads. It is critical to use an external guide system or a guided cylinder to absorb any transverse forces, preventing premature seal wear and rod damage. For a direct replacement, match the 40 mm bore, 1600 mm stroke, PT1/4 port thread, basic mounting configuration, and ensure the original unit was also a non-magnet version.
Quick checklist
At the standard 0.5 MPa operating pressure, the theoretical 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.
A 1600 mm stroke on a 16 mm rod is vulnerable to buckling and side-load damage. You must install an external linear guide rail or use a guided cylinder variant to support the load and absorb any off-axis forces, ensuring the rod moves in a perfectly straight line.
