The AirTAC Airtac SC40 Standard Cylinder SC40X600H is a genuine double-acting standard air cylinder with a Ø40mm bore and 600mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X600H is a double-acting single-rod pneumatic cylinder with a 40 mm bore and 600 mm stroke, factory-equipped with Viton (FKM) seals for reliable operation in high-temperature environments up to 150 °C. At 0.5 MPa air pressure it delivers 628 N pushing force and 528 N pulling force, making it a capable mid-range actuator for thermal-process automation.
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 (21 mm cushion length) decelerates the piston smoothly, while the tie-rod construction keeps the 142 mm body length A compact for its stroke class. With a 600 mm stroke, this cylinder is within the 1200 mm maximum standard stroke for the 40 mm bore.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The Viton seals allow this cylinder to operate continuously in ovens, dryers, or autoclaves where ambient temperatures reach 150 °C, reliably opening and closing hot-air gates or dampers.
Provides consistent 628 N clamping force on heated plastic sheet tooling, with the 600 mm stroke offering ample daylight for loading and unloading formed parts.
Delivers a steady push force for adhesive bonding or laminating presses that run hot, resisting seal degradation far longer than standard NBR or TPU sealed cylinders.
Choose the SC40 bore when your application needs between roughly 500 N and 1100 N of push force at standard plant air pressures. If you require more force, stepping up to the SC50 bore provides 982 N push at 0.5 MPa; for lighter, faster cycling, the SC32 bore offers 402 N push at 0.5 MPa. For this 600 mm stroke, ensure the rod is not subjected to significant side loading—long, unsupported rods can bend under lateral force. An external linear guide or a guided cylinder should be used when the load is not perfectly axial.
To replace an existing SC40X600H, match five points exactly: 40 mm bore, 600 mm stroke, PT port thread, basic (no integral mounting bracket), and the H suffix for Viton seals. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard maximum operating pressure of 1.0 MPa, the theoretical push force is 1130 N. At a typical plant pressure of 0.5 MPa, push force is 628 N and pull force (rod side) is 528 N. The maximum theoretical force at 1.0 MPa is 128 kgf.
No. The SC40X600H is a standard double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. To hold a load securely without live pressure, you must add an external rod lock, a pilot-operated check valve, or a mechanical brake.
