The AirTAC Airtac SC40 Standard Cylinder SC40X1425 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1425mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1425 is a double-acting tie-rod cylinder with a 40 mm bore and a non-standard 1425 mm stroke, exceeding the standard maximum of 1200 mm for this bore size. It delivers 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 automation.
This model features a 16 mm diameter piston rod with an M12x1.25 male thread and PT1/4 ports. The adjustable pneumatic cushion at each end (21 mm cushion length) decelerates the piston smoothly, while the body length A of 142 mm keeps the overall footprint compact relative to its extended reach.

The 1425 mm stroke pushes or pulls parts across wide conveyor gaps or between distant workstations in automated packaging lines.
Provides long-travel clamping for large fabricated assemblies, moving the clamp jaw into position before applying 628 N of holding force at 0.5 MPa.
Operates roof or side vents in agricultural buildings, using its long stroke to open large louvre panels for climate control.
For applications requiring a 40 mm bore, the SC40X1425 provides 628 N of push force at 0.5 MPa. If your load demands more force, stepping up to the 50 mm bore (SC50) offers 982 N at the same pressure. For lighter, faster cycles, the 32 mm bore (SC32) provides 402 N.
This is a non-standard, made-to-order stroke length. When replacing an existing unit, match the 40 mm bore, 1425 mm stroke, PT1/4 port thread, basic mounting configuration, and confirm the magnet requirement. For strokes of this length, side loads must be avoided; use an external guide rail or rod support to prevent bending of the 16 mm rod.
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 reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. For a 1425 mm stroke with a 16 mm rod, side loading or unsupported weight can cause rod bending and premature seal wear. Always install an external linear guide or use a guided cylinder variant to absorb transverse forces.
