The AirTAC Airtac SC40 Standard Cylinder SC40X1590S 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.
This AirTAC SC40X1590S is a double-acting single-rod tie-rod cylinder with a 40 mm bore and a non-standard 1590 mm stroke, built for applications that need extended linear reach. It delivers a push force of 628 N at 0.5 MPa and reaches 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod with M12x1.25 threads.
The cylinder body length A is 142 mm, giving a total extended length of approximately 1732 mm. It features an adjustable pneumatic cushion (21 mm) at both ends to decelerate the piston smoothly. The integrated -S magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the barrel for precise position feedback.

The 1590 mm stroke is ideal for pushing boxes or products off a conveyor line deep within a packaging station, where a compact retracted length is needed for machine clearance.
Delivers a smooth, extended linear motion for a glue head or sealant nozzle across large panels, with the -S magnet providing stroke-end confirmation to the PLC.
Operates a tall gate or diverter flap on a conveyor system. The 16 mm rod and adjustable cushion handle the repetitive end-of-stroke impact reliably.
Select the SC40 bore when 628 N at 0.5 MPa meets your load requirement; for higher force, step up to the SC50 which provides 982 N at the same pressure. For lighter, faster applications, the SC32 offers 402 N. This 1590 mm stroke exceeds the standard maximum of 1200 mm for a 40 mm bore, making it a made-to-order item.
For strokes of this length, the unsupported 16 mm rod is susceptible to bending under side loads. You must use an external linear guide or rod support to prevent buckling and premature seal wear. When replacing, match the bore, stroke, PT port thread, basic mounting, and ensure the replacement has the -S magnet for sensor compatibility.
Quick checklist
At the standard 0.5 MPa operating pressure, 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 at 1.0 MPa is 128 kgf.
A stroke exceeding 300 mm on a 16 mm rod carries a risk of rod buckling and uneven bearing wear if side loads are present. You must guide the load externally with a linear rail or rod support, or switch to a guided cylinder assembly. The SC cylinder itself is not designed to absorb lateral forces.
