The AirTAC Airtac SC40 Standard Cylinder SC40X320S is a genuine double-acting standard air cylinder with a Ø40mm bore and 320mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X320S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 320 mm stroke. At 0.5 MPa it provides 628 N of push force and 528 N of pull force, while at the maximum operating pressure of 0.9 MPa the thrust reaches 1130 N, driven by a 16 mm diameter piston rod.
The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for non-contact position sensing. With a body length A of 142 mm, the total extended length is approximately 462 mm. The adjustable air cushion at each end decelerates the piston smoothly within a 21 mm cushion zone.

The 320 mm stroke and sensor-ready magnet make this cylinder ideal for actuating diverter gates on packaging or food-grade conveyors, where mid-stroke position confirmation is required.
Delivers 1130 N of clamping force at 0.9 MPa for holding workpieces during drilling or welding. The magnetic piston enables end-of-stroke verification for automated assembly sequences.
Used in life-cycle test rigs to apply a consistent 628 N push force. The adjustable cushion protects the cylinder and fixture from impact damage during high-speed cycling.
This 40 mm bore cylinder is a balanced choice for medium-force applications. If your load requires more force, stepping up to the 50 mm bore provides 982 N at 0.5 MPa. For lighter, faster cycles, the 32 mm bore offers 402 N. The 320 mm stroke is within the 1200 mm maximum standard stroke for this bore.
For strokes of 300 mm or more, be cautious of side loads on the 16 mm rod. An unsupported rod under lateral force can bend or damage the bearing. Use an external linear guide or a guided cylinder to absorb side forces. When replacing an existing unit, match five points: 40 mm bore, 320 mm stroke, PT port thread, the built-in magnet (-S), and basic (no mounting accessory) configuration.
Quick checklist
At the standard operating pressure of 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 force at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without additional brackets.
