The AirTAC Airtac SC40 Standard Cylinder SC40X1420S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1420mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1420S is a double-acting single-rod tie-rod cylinder with a 40 mm bore and an extended 1420 mm non-standard stroke, exceeding the standard 1200 mm maximum for this bore size. It delivers 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 model includes a built-in magnet, allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise position feedback. The cylinder body length A is 142 mm, and it operates on filtered air from 0.15 to 1.0 MPa with an adjustable pneumatic cushion at each end.

Pushes or pulls lightweight components across a 1420 mm span on a conveyor line, with sensor confirmation of full extension and retraction.
Operates a tall diverter gate in a logistics sorting system, where the magnet confirms the gate is fully open or closed.
Applies a 628 N clamping force at 0.5 MPa on a large assembly jig, with the long stroke clearing the part for easy loading.
For applications requiring this force class, stepping up to a 50 mm bore provides 982 N of push force at 0.5 MPa, while a 32 mm bore offers 402 N. The 1420 mm stroke is non-standard and made-to-order; for such a long extension, the 16 mm rod is susceptible to bending under side loads, so an external linear guide or a guided cylinder is strongly recommended to prevent rod bearing damage. When replacing this unit, match the bore, stroke, PT port thread, the built-in magnet (-S suffix), and the basic mounting configuration.
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.
No, the maximum standard stroke for the 40 mm bore SC cylinder is 1200 mm. The 1420 mm stroke is a non-standard, made-to-order length.
