The AirTAC Airtac SC40 Standard Cylinder SC40X350S is a genuine double-acting standard air cylinder with a Ø40mm bore and 350mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X350S 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 350 mm stroke suit mid-range linear tasks where sensor feedback is required.
This model includes a factory-installed magnet (suffix -S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable end-of-stroke detection. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration, while the PT1/4 port and M12x1.25 rod thread ensure straightforward pneumatic connections.

The 350 mm stroke moves components between conveyor lanes, while the built-in magnet and CMSG/DMSG sensors confirm extend and retract positions to the PLC for reliable automation sequencing.
Provides 628 N of clamping force for jigs and fixtures. The magnetic piston enables precise sensor feedback to verify the clamp is fully engaged before a machining or joining cycle starts.
Pushes cartons or products off a line with a 350 mm stroke. The integrated magnet allows easy addition of sensors to detect product presence and prevent machine jams without external flag switches.
Choose the SC40X350S when your application needs approximately 628 N at standard shop pressure and integrated position sensing. If you require more force, step up to the SC50 bore (982 N push at 0.5 MPa); for a lighter, more compact solution, the SC32 bore offers 402 N.
For this 350 mm stroke, be mindful of side loads. Long, unsupported piston rods are susceptible to bending under lateral force. If your load is not guided externally, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearing and seals. When replacing an existing cylinder, match five key points: 40 mm bore, 350 mm stroke, PT1/4 port thread, the built-in magnet (-S), and your specific mounting accessory.
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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The 'S' suffix in SC40X350S indicates a built-in magnet on the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the cylinder barrel for non-contact position sensing.
