The AirTAC Airtac SC40 Standard Cylinder SC40X75S 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 AirTAC SC40X75S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 75 mm stroke suit compact linear tasks where mid-range force and moderate travel are needed, and the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for end-of-stroke detection.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at each end. The standard TPU seals provide reliable operation from -20 to +70 °C.

The 75 mm stroke and magnetic piston make this cylinder ideal for diverting small packages on a conveyor. The built-in magnet triggers a reed sensor to confirm each actuation cycle.
With 628 N of clamping force at 0.5 MPa, the SC40X75S securely holds workpieces during light machining or assembly. Sensor feedback confirms the clamp is closed before the cycle starts.
The clean, tie-rod design and sensor-ready body suit lab automation equipment. Use the 75 mm stroke to move test tube racks or pipette heads with position verification via DMSG sensors.
Choose the SC40 bore when your application needs roughly 600-1100 N of force from standard shop air. If you require more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact actuator, the SC32 provides 402 N. This 75 mm stroke is well within the 1200 mm maximum standard stroke for the 40 bore.
For replacement, match five points: 40 mm bore, 75 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and your required mounting accessory (this is a basic body, order feet or flanges separately if needed). Always use an external guide or linear rail if the rod will see side loads.
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. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without external brackets.
