The AirTAC Airtac SC40 Standard Cylinder SC40X750S is a genuine double-acting standard air cylinder with a Ø40mm bore and 750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X750S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore, 16 mm piston rod, and a 750 mm stroke, this model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for contactless position sensing.
This cylinder uses PT1/4 ports and an M12x1.25 rod thread, with an adjustable air cushion (21 mm length) at both ends to decelerate the piston smoothly. The body length A is 142 mm, giving a total extended length of approximately 892 mm. Operating on filtered air from 0.15 to 1.0 MPa, the TPU/NBR seals suit a standard temperature range of -20 to +70 °C.

The 750 mm stroke and sensor-ready design make it ideal for stopping or transferring boxes and totes on wide conveyors, where mid-stroke and end-stroke position confirmation is required.
Delivers 628 N at standard line pressure to press components into fixtures. The built-in magnet allows for multi-position sensing to verify each step of the assembly sequence.
Suitable for opening and closing hopper gates or diverter chutes with a 750 mm travel. The adjustable cushioning protects the end caps from impact at the end of the long stroke.
The SC40 bore sits between the smaller SC32 (402 N at 0.5 MPa) and the larger SC50 (982 N at 0.5 MPa). If your load requires more force, stepping up to the SC50 provides a significant 56% increase in push capacity. For this 750 mm stroke, ensure the rod is not subjected to significant side loading; at extended lengths, the 16 mm rod can bend under lateral force. Consider an external guide rail or a guided cylinder if the load is not purely axial.
For a direct replacement, match five key points: 40 mm bore, 750 mm stroke, PT1/4 port thread, the built-in magnet for sensors, and the basic (no bracket) mounting style. This is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to clamp compatible CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without any additional brackets.
