About the Airtac SC40 Standard Cylinder SC40X1000
The AirTAC SC40X1000 is a double-acting tie-rod cylinder delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure. With a 40 mm bore and a full 1000 mm stroke—the maximum standard stroke for this bore size—it suits long-travel linear applications where consistent pneumatic force is needed.
This model features a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 port connections. The body length A is 142 mm, giving a total extended length of approximately 1142 mm. An adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The standard TPU seals provide reliable operation from -20 to +70 °C.

Where the Airtac SC40 Standard Cylinder SC40X1000 Is Used
Long-Reach Part Transfer
Moves components across a 1000 mm span on packaging or assembly lines, using the full standard stroke to shuttle parts between distant stations without intermediate stops.
Material Pusher on Wide Conveyors
Pushes products off a wide belt conveyor into a chute or bin. The 628 N push force at 0.5 MPa handles moderate-weight items, while the adjustable cushion prevents product damage at stroke end.
Vertical Gate or Hopper Door Actuator
Opens and closes a tall sliding gate on a hopper or silo discharge. The 1000 mm stroke provides full gate travel, and the double-acting function ensures positive opening and closing under load.
Is the Airtac SC40 Standard Cylinder SC40X1000 the Right Cylinder?
Select the SC40 bore when your application requires a force between 528 N (pull at 0.5 MPa) and 1130 N (push at 0.9 MPa). If you need more force, step up to the SC50 bore which provides 982 N push at 0.5 MPa; for a lighter, more compact solution, the SC32 bore delivers 402 N push at 0.5 MPa. This 1000 mm stroke is at the maximum standard limit for a 40 mm bore—verify that the rod is adequately supported against buckling under compressive loads.
For strokes of 300 mm or longer, side loading on the extended rod becomes a critical design factor. The 16 mm rod on this SC40X1000 can bend if subjected to radial forces when fully extended. Use an external linear guide or a guided cylinder variant to absorb side loads and protect the rod bearing and piston seals. When replacing an existing cylinder, match all five key points: bore (40 mm), stroke (1000 mm), port thread (PT1/4), mounting accessory, and magnet option (none on this basic model).
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 SC40X1000 FAQ
At the standard 0.5 MPa operating pressure, 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.
Only if the load is purely axial and perfectly aligned. A 1000 mm stroke with a 16 mm rod is susceptible to bending and buckling under side loads or high compressive forces. For any off-axis loading, install an external linear guide rail or select a guided cylinder to prevent rod damage and premature seal wear.
