The AirTAC Airtac SC40 Standard Cylinder SC40X1450S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1450mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1450S is a double-acting single-rod pneumatic cylinder with a 40 mm bore and an extra-long 1450 mm non-standard stroke. It generates 628 N of push force and 528 N of pull force at 0.5 MPa, rising to 1130 N push at 0.9 MPa. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration.
This model includes a built-in magnet (-S suffix), allowing easy mounting of CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the tie-rod barrel for precise position feedback. As a non-standard stroke exceeding the 1200 mm maximum for 40 mm bore, this cylinder is made-to-order. The body length A is 142 mm, giving a total extended length of approximately 1592 mm.

The 1450 mm stroke moves components across wide conveyor gaps or between distant workstations in automated assembly lines.
Operates tall diverter gates or flippers in material handling systems, using sensor feedback from the built-in magnet for precise positioning.
Provides extended vertical lift for lightweight tooling or sensor masts in warehouse automation, where the 16 mm rod is externally guided.
Choose the SC40 when the 628 N force at 0.5 MPa fits your application. If you need more force, step up to the 50 mm bore SC50 series, which provides 982 N at the same pressure. For lighter, faster cycles, the 32 mm bore SC32 offers 402 N. This 1450 mm stroke is non-standard; for such a long unsupported rod, external guides or a guided cylinder are strongly recommended to prevent rod bending and bearing wear under side loads. For replacement, match bore (40 mm), stroke (1450 mm), port thread (PT1/4), the built-in magnet (-S), and basic mounting.
Quick checklist
At the standard operating pressure of 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 reaches 1130 N.
No, the maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm. The 1450 mm stroke is a non-standard, made-to-order length. For such long strokes, an external guide mechanism is essential to protect the 16 mm rod from side-load bending.
