The AirTAC Airtac SC40 Standard Cylinder SC40X1590 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1590mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1590 is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1590 mm stroke, exceeding the standard 1200 mm maximum for this bore size. It generates a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, making it suitable for long linear movements in material handling or process automation.
This model features a 16 mm diameter piston rod with an M12x1.25 thread and a 21 mm adjustable air cushion at each end to decelerate the load. The body length A is 142 mm, and the total extended length is approximately 1732 mm. Ports are PT1/4, and the default TPU seals provide an operating temperature range of -20 to +70 C.

Moves components across a wide gap between conveyor lines, using its 1590 mm stroke to bridge distances that standard cylinders cannot cover.
Opens and closes a tall industrial door or gate, where the extended stroke provides the necessary travel without a complex linkage system.
Extends a glue applicator nozzle across a large panel, delivering consistent force at 0.5 MPa for a uniform bead over a long distance.
Select the SC40 when your application requires a force around 628 N at standard shop air. If you need more thrust, step up to the SC50 bore, which provides 982 N at 0.5 MPa. For a lighter, more compact solution, the SC32 delivers 402 N.
For this 1590 mm stroke, side-load management is critical. The long, unsupported 16 mm rod is susceptible to bending under lateral forces. You must use an external linear guide or rod support to prevent bearing damage and ensure smooth operation. When replacing an existing cylinder, match five key points: the 40 mm bore, the 1590 mm stroke, the PT1/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet.
Quick checklist
At 0.5 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.
A stroke of 1590 mm with a 16 mm rod creates a high risk of buckling and side-load damage. You must guide the load externally with a linear rail or rod support. The cylinder itself should never bear side loads; it is designed for axial push/pull forces only.
