The AirTAC Airtac SC40 Standard Cylinder SC40X1070S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1070mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1070S is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 1070 mm stroke make it a strong candidate for long-reach material transfer or sorting gates where a compact tie-rod body is preferred over bulkier profile cylinders.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke detection. The 16 mm diameter piston rod and 21 mm adjustable air cushion at each end help manage deceleration, while the PT1/4 port threads keep plumbing simple. The body length A is 142 mm, giving an extended length of approximately 1212 mm.

The 1070 mm stroke with 628 N push force at 0.5 MPa efficiently operates a long-travel reject gate on a conveyor line, pushing defective products into a side chute with sensor-confirmed end positions via the built-in magnet.
Lifts small bins or totes in a vertical storage module. The 16 mm rod and adjustable cushion provide controlled ascent and descent, while the -S magnet confirms the home position at the bottom of the 1070 mm travel.
Extends a glue nozzle across a 1070 mm panel width. The tie-rod SC design offers a rigid, stable platform for the long stroke, and the magnetic piston allows programmable multi-point positioning with DMSG sensors.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N at 0.5 MPa. If a shorter, more compact build is required, the 32 mm bore SC32 delivers 402 N. At 1070 mm stroke, the rod is fully supported within the standard stroke range for the 40 mm bore (max 1200 mm). For any stroke over 300 mm, always check for side loads—an external guide rail or a guided cylinder is recommended to protect the rod bearing from bending moments. When replacing an existing unit, match five points: 40 mm bore, 1070 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
Quick checklist
At 0.7 MPa operating pressure, the push force is 879 N and the pull force on the retract stroke is 528 N. The maximum theoretical force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in SC40X1070S designates a built-in magnet. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without any additional brackets.
