The AirTAC Airtac SC40 Standard Cylinder SC40X75SN 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 SC40X75SN is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range automation tasks.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection without external brackets. The NBR seal material offers good resilience for general industrial environments, while the standard PT1/4 port thread ensures straightforward pneumatic connection.

Operates diverter gates and stops on light-duty conveyor lines, where the 628 N push force easily moves packages and the magnetic sensors confirm gate position.
Provides consistent clamping force for assembly jigs and welding fixtures. The NBR seals handle shop air conditions, while the 16 mm rod resists deflection under axial loads.
Drives push-and-eject mechanisms in cartoners and case packers. The adjustable cushion absorbs impact at the 75 mm stroke end, reducing noise and extending seal life.
For higher force requirements, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If space is constrained, the 32 mm bore SC32 series offers 402 N. This 75 mm stroke is a standard length for the 40 mm bore family, which supports strokes up to 1200 mm.
When replacing an existing cylinder, match five key points: bore (40 mm), stroke (75 mm), port thread (PT1/4), the built-in magnet sensor option (-S), and the basic mounting style. Always verify the tie-rod body length (A=142 mm) matches your available space, as the SC series is shorter than ISO 15552 cylinders.
Quick checklist
At 0.5 MPa supply pressure, the cylinder produces 628 N extending (push) and 528 N retracting (pull). 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 in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without any additional mounting hardware.
