About the Airtac SC40 Standard Cylinder SC40X590S
The AirTAC SC40X590 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). Its 40 mm bore and 16 mm piston rod are paired with a 590 mm stroke, making it suitable for medium-reach linear tasks where a compact body length is required.
This model features an adjustable air cushion (21 mm length) to decelerate the piston smoothly at end-of-stroke. The body length A is 142 mm, giving a total extended length of approximately 732 mm. Standard PT1/4 ports and an M12x1.25 rod thread are included, with TPU seals rated for -20 to +70 °C.

Where the Airtac SC40 Standard Cylinder SC40X590S Is Used
Part Transfer
Pushes or diverts medium-weight packages and components on conveyor lines with a 590 mm reach, using 628 N of force at 0.5 MPa.
Clamping & Fixturing
Applies consistent clamping pressure in woodworking or light metalworking jigs, where the 40 mm bore provides ample force without overbuilding.
Bin Gate Actuation
Operates sliding gates or diverter chutes on hoppers and silos, leveraging the long 590 mm stroke for full gate travel.
Is the Airtac SC40 Standard Cylinder SC40X590S the Right Cylinder?
Choose the SC40X590 when your application needs around 628 N of force at standard plant air pressure. If you need more force, stepping up to the 50 mm bore (SC50) provides 982 N push at 0.5 MPa. For lighter, faster cycles, the 32 mm bore (SC32) offers 402 N. With a 590 mm stroke, ensure side loads are minimal or use an external guide; the 16 mm rod can bend under off-axis forces at full extension.
For a direct replacement, match five points: 40 mm bore, 590 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. This SC cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC40 Standard Cylinder SC40X590S FAQ
At 0.5 MPa, push force is 628 N and pull force is 528 N. At 0.7 MPa, push force increases to 879 N. The maximum operating pressure is 1.0 MPa, yielding 1130 N push.
No. The SC40X590 is a double-acting cylinder and does not lock or hold position when pressure is exhausted. The piston will drift or drop. For load holding, add a pilot-operated check valve or an external mechanical rod brake.
