About the Airtac SC50 Standard Cylinder SC50X1540
The AirTAC SC50X1540 is a double-acting pneumatic cylinder with a 50 mm bore and an extended 1540 mm stroke, built to order beyond the standard 1200 mm maximum for this bore size. It produces 982 N of push force and 825 N of pull force when operated at 0.5 MPa, making it suitable for long linear movements in material handling or process automation.
This model features a 20 mm diameter piston rod with an M16x1.5 male thread, PT1/4 port connections, and a 21 mm adjustable air cushion at each end. The body length A is 150 mm, giving a total extended length of approximately 1690 mm. With a maximum operating pressure of 1.0 MPa, the cylinder can deliver up to 1767 N of push force for demanding actuation tasks.

Where the Airtac SC50 Standard Cylinder SC50X1540 Is Used
Long-Reach Material Transfer
The 1540 mm stroke moves heavy bins or pallets across wide conveyor gaps, using 982 N of push force at standard line pressure.
Automated Gluing or Welding
Extends a dispensing or welding head across a large workpiece, maintaining consistent speed with the cylinder's adjustable cushion for smooth stops.
Vertical Lift Assistance
Provides 825 N of pulling force to raise a platform or access panel over a long vertical distance in a storage or maintenance system.
Is the Airtac SC50 Standard Cylinder SC50X1540 the Right Cylinder?
This SC50X1540 is a non-standard stroke model, ideal when a 50 mm bore cylinder must travel beyond the standard 1200 mm limit. If your application requires higher force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N of push force at 0.5 MPa. For a shorter, standard stroke, the SC50 series offers lengths from 25 mm to 1200 mm.
At a 1540 mm stroke, the piston rod is highly extended and vulnerable to bending under side loads. It is strongly recommended to use an external linear guide or a guided cylinder to prevent rod bearing damage and ensure long service life. When replacing an existing cylinder, match the 50 mm bore, 1540 mm stroke, PT1/4 port thread, basic mounting, and the absence of a magnet to ensure a direct fit.
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 SC50 Standard Cylinder SC50X1540 FAQ
At the maximum operating pressure of 1.0 MPa, the push force is 1767 N. At a typical factory air pressure of 0.7 MPa, it delivers 1374 N of push force.
No. The maximum standard stroke for a 50 mm bore SC cylinder is 1200 mm. A 1540 mm stroke is a non-standard, made-to-order length, which may have a longer lead time.
