About the Airtac SC40 Standard Cylinder SC40X1450
The AirTAC SC40X1450 is a double-acting tie-rod cylinder engineered for applications demanding an extra-long 1450 mm stroke from a compact 40 mm bore. At 0.5 MPa it generates 628 N pushing force and 528 N on the retract, scaling to 1130 N at the maximum operating pressure of 0.9 MPa. This model uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 pneumatic ports.
With a body length A of 142 mm, the total extended length reaches approximately 1592 mm. Because the 1450 mm stroke exceeds the standard maximum of 1200 mm for the 40 bore, this is a non-standard, made-to-order configuration. The cylinder includes a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, protecting end caps during high-cycle operation.

Where the Airtac SC40 Standard Cylinder SC40X1450 Is Used
Long-Reach Part Transfer
Moves components 1450 mm across wide conveyor gaps or between distant workstations in automated assembly lines.
Vertical Door Actuation
Opens and closes tall access panels or machine guarding doors where a long, guided stroke is essential for full clearance.
Bulk Material Pusher
Pushes lightweight products or rejects off a wide belt into chutes, leveraging the full 1450 mm reach without occupying excessive lateral space.
Is the Airtac SC40 Standard Cylinder SC40X1450 the Right Cylinder?
Choose the SC40 bore when 628 N at 0.5 MPa matches the load with a safety margin; if more force is needed, step up to the SC50 which delivers 982 N at the same pressure. For strokes of this length, the unsupported rod is susceptible to bending under side loads—always use an external linear guide or rod-alignment coupler to prevent bearing wear and seal failure. When replacing an existing unit, match five points exactly: 40 mm bore, 1450 mm stroke, PT1/4 port thread, basic mounting (no bracket), and no magnet.
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 SC40X1450 FAQ
At 0.7 MPa the SC40X1450 produces 879 N of force when extending (push) and 739 N when retracting (pull). The theoretical maximum at 1.0 MPa is 128 kgf, though the operating limit is 1.0 MPa.
No, the maximum standard stroke for the 40 mm bore SC cylinder is 1200 mm. The 1450 mm stroke is a non-standard, made-to-order configuration that requires special production and a longer lead time.
