The AirTAC SC40 Standard Cylinder SC40X1400 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1400mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1400 is a double-acting single-rod pneumatic cylinder with a 40 mm bore and an extended 1400 mm stroke, which exceeds the standard maximum of 1200 mm for this bore size, making it a made-to-order unit. It generates a push force of 628 N at 0.5 MPa and 1130 N at 0.9 MPa, driven by a 16 mm diameter piston rod with an M12x1.25 knuckle thread.
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 1542 mm. Ports are PT1/4, and the standard TPU seals provide an operating temperature range of -20 to +70 °C.

The 1400 mm stroke is well-suited for pushing bins or pallets across wide roller conveyors in distribution centers, where the 628 N force at 0.5 MPa handles medium-weight loads.
Provides a long, controlled linear motion for moving a glue head or sealant nozzle across large workpieces, with the adjustable cushion ensuring a smooth stop without vibration.
Operates large ventilation dampers or sliding gates in agricultural buildings, leveraging its double-acting control for both opening and closing over a significant travel distance.
For applications requiring less force, consider stepping down to the SC32 bore, which provides 402 N of push force at 0.5 MPa. If a higher force is needed, the SC50 offers 982 N at the same pressure. With a 1400 mm stroke, this cylinder's long, 16 mm rod is susceptible to bending under side loads; an external linear guide or a guided cylinder assembly is strongly recommended to protect the rod bearing and ensure reliable operation.
When replacing an existing cylinder, ensure a precise match across five key points: bore (40 mm), stroke (1400 mm), port thread (PT1/4), mounting accessory (basic, no bracket), and the presence of a magnet (none on this model). This SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 increases to 1130 N.
No, the maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm. A 1400 mm stroke is a non-standard, made-to-order configuration. For such a long stroke, using an external guide is critical to prevent rod bending and premature seal wear.
