The AirTAC Airtac SC40 Standard Cylinder SC40X375 is a genuine double-acting standard air cylinder with a Ø40mm bore and 375mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X375 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force and 528 N of pull force when operated at 0.5 MPa. With a 40 mm bore and a 375 mm stroke, it is built for linear applications needing a compact yet robust actuator. The piston rod measures 16 mm in diameter, and the cylinder body length A is 142 mm, giving a total extended length of approximately 517 mm.
This model features PT1/4 port threads and an M12x1.25 rod thread for standard pneumatic connections. The adjustable air cushion at each end, with a 21 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact. Operating on filtered air from 0.15 to 1.0 MPa, it uses standard TPU seals for a temperature range of -20 to +70 °C.

The 375 mm stroke and 628 N push force at 0.5 MPa make this cylinder ideal for actuating gates or diverters on packaging conveyors, providing a firm, repeatable motion to route products.
Use the SC40X375 in jigs and fixtures for part clamping during welding or assembly. The adjustable cushion prevents impact shock that could disturb part alignment.
With a 16 mm rod and 375 mm reach, this cylinder can push bins or totes off a gravity roller lane in warehouse sorting systems, offering a cost-effective pneumatic solution.
Choose the SC40 bore when your application requires between 528 N and 1130 N of force at standard shop air pressures. If you need more force, stepping up to the SC50 bore provides 982 N of push force at the same 0.5 MPa. For strokes of 300 mm or more like this 375 mm model, be aware that side loads can cause bending stress on the 16 mm rod; use an external guide or ensure the load is perfectly axial to maximize bearing and seal life. When replacing an existing cylinder, match five points: 40 mm bore, 375 mm stroke, PT1/4 port thread, basic mounting (no bracket), and confirm whether a magnet is needed (this model has none).
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.
No. The AirTAC SC series is a tie-rod cylinder that is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a drop-in interchange. It is a direct replacement only for another AirTAC SC tie-rod cylinder with identical bore, stroke, port thread, and mounting configuration.
