The AirTAC Airtac SC40 Standard Cylinder SC40X730S is a genuine double-acting standard air cylinder with a Ø40mm bore and 730mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X730S is a double-acting tie-rod cylinder with a 40 mm bore and a 730 mm stroke, delivering 628 N of push force at 0.5 MPa (1130 N at the 0.9 MPa maximum operating pressure). Its 16 mm diameter piston rod and 21 mm adjustable air cushion help manage end-of-stroke deceleration across the long travel.
This model includes the -S suffix, indicating a built-in magnet that allows CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for non-contact position sensing. The body length A is 142 mm, giving a total extended length of approximately 872 mm, and it uses a PT1/4 port with an M12x1.25 rod thread.

The 730 mm stroke and magnetic piston sensing make it ideal for long-reach material stops or lane diverters on packaging conveyors, where end-of-stroke confirmation is required.
Pushes components across a 730 mm transfer distance in automated assembly cells. The built-in magnet provides mid-stroke and end-stroke sensor feedback to the PLC.
Operates a sorting gate or deflector arm in logistics systems, using the 628 N force to reliably move product totes across a wide conveyor merge point.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at 0.5 MPa. With a stroke of 730 mm, ensure the rod is not subjected to significant side loading; an external linear guide or a guided cylinder configuration is recommended to prevent rod bearing wear and bending over this extended reach.
When replacing an existing cylinder, match five key points: 40 mm bore, 730 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic tie-rod mounting footprint. This SC model is shorter than an ISO 15552 cylinder and is not a drop-in dimensional interchange for that standard.
Quick checklist
At the standard 0.5 MPa operating pressure, 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.
Yes. The -S suffix means this cylinder has a built-in magnet on the piston. You can clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the barrel to detect piston position without additional brackets.
