The AirTAC SC40 Standard Cylinder SC40X320N 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 AirTAC SC40X320N is a double-acting tie-rod cylinder with a 40 mm bore and 320 mm stroke, fitted with NBR (nitrile) seals for standard-temperature pneumatic circuits. At 0.5 MPa it generates 628 N pushing force and 528 N pulling force, rising to 1130 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 ports. The adjustable air cushion at each end provides a 21 mm deceleration zone, and the body length A is 142 mm. With a 320 mm stroke the total extended length reaches 462 mm, making it a compact workhorse for medium-reach clamping and transfer tasks.

Moves components between conveyor lanes or assembly nests with a 320 mm stroke. The 628 N push force at 0.5 MPa handles medium pallets and fixtures reliably.
Applies consistent clamping pressure in CNC jigs and welding fixtures. NBR seals offer good resilience for repetitive cycling in clean, room-temperature environments.
Operates sliding safety doors or interlock gates on packaging machinery. The adjustable cushioning reduces end-of-stroke impact, extending the life of door guides.
Choose the SC40 when 628 N at 0.5 MPa covers your load with a safety factor; if you need more force, stepping up to the SC50 delivers 982 N push at the same pressure. For strokes of 300 mm or more, always check side-load conditions—a 16 mm rod extended 320 mm can bend under off-axis force. Use an external linear guide or a guided cylinder if the load is not perfectly aligned with the rod axis.
To replace an existing cylinder, match five points: 40 mm bore, 320 mm stroke, PT1/4 port thread, basic (no mounting accessory) configuration, and no magnet. The SC40X320N uses NBR seals, so confirm seal compatibility with your operating environment.
Quick checklist
At 0.5 MPa the cylinder delivers 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder—it is not interchangeable. Replace only with another AirTAC SC tie-rod cylinder or an equivalent tie-rod design matching the 40 mm bore, 320 mm stroke, PT1/4 ports, and NBR seals.
