About the Airtac SC40 Standard Cylinder SC40X1200
The AirTAC SC40X1200 is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 1200 mm stroke suit long linear movements in material handling and packaging machinery.
Built on a tie-rod construction with a 16 mm diameter chrome-plated rod and M12x1.25 rod thread, this cylinder includes an adjustable air cushion (21 mm cushion length) to decelerate the piston smoothly at stroke ends. The body length A is 142 mm, giving a total extended length of approximately 1342 mm.

Where the Airtac SC40 Standard Cylinder SC40X1200 Is Used
Long-Stroke Material Transfer
Pushes or pulls trays and pallets across wide conveyor gaps, using the full 1200 mm stroke for extended reach in automated lines.
Packaging & Palletising
Operates pusher arms or layer-forming mechanisms in packaging stations where consistent force and long travel are required.
Woodworking & Panel Saws
Positions fence stops or clamps on long-bed machinery, benefiting from the adjustable cushion for smooth, impact-free stopping.
Is the Airtac SC40 Standard Cylinder SC40X1200 the Right Cylinder?
Choose the SC40X1200 when 628 N push force at 0.5 MPa matches your load. If you need more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N. At this 1200 mm stroke, the rod is fully supported by the front bearing, but any side load can cause rod deflection or bearing wear—use an external linear guide or a guided cylinder for non-axial loads.
For a direct replacement, match these five points: bore (40 mm), stroke (1200 mm), port thread (PT1/4), mounting accessory (basic, no bracket), and magnet option (none). This model uses the default TPU seals and PT ports.
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 SC40X1200 FAQ
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, 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 with a shorter body length than ISO 15552 profile cylinders, so mounting dimensions are not interchangeable. It directly replaces another AirTAC SC40 cylinder with the same stroke, port, and mounting configuration.
