The AirTAC SC40 Standard Cylinder SC40X75SFB is a genuine double-acting standard air cylinder with a Ø40mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X75SFB is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 75 mm stroke. At 0.5 MPa it generates 628 N pushing force, while the 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, plus an FB rear rectangular flange (F-SC40FB) for rigid cap-end mounting. The standard PT1/4 port and TPU seals suit filtered-air systems operating from -20 to +70 °C.

The 75 mm stroke and rear flange mount suit diverters or gates on packaging conveyors, where the magnet enables end-of-stroke sensing for high-cycle counting.
Delivers 628 N at 0.5 MPa for consistent clamping of components in CNC fixtures or assembly jigs, with the FB flange securing the cylinder against the fixture plate.
Ideal for laboratory test rigs requiring a compact 75 mm stroke actuator. The built-in magnet allows easy integration of reed switches for position feedback.
Choose the SC40 bore when your application needs around 628 N of push force at standard shop air; if you require roughly 982 N, step up to the SC50. For strokes of 300 mm or longer, evaluate side-load conditions—an external guide or guided cylinder may be necessary to protect the 16 mm rod from bending. When replacing an existing unit, match five points: 40 mm bore, 75 mm stroke, PT1/4 port thread, FB rear flange mounting, and the -S magnet for sensor compatibility.
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.
Yes. The -S suffix indicates a built-in magnet, so AirTAC CMSG, DMSG, or EMSG sensors can be clamped directly onto the barrel for non-contact position detection.
