About the Airtac SC50 Standard Cylinder SC50X1565
The AirTAC SC50X1565 is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 20 mm diameter piston rod, this model is built for medium-duty linear tasks requiring a long reach.
This specific 1565 mm stroke exceeds the standard maximum of 1200 mm for the 50 bore, making it a non-standard, made-to-order unit. The cylinder features a PT1/4 port, an M16x1.5 rod thread, and a 21 mm adjustable air cushion to decelerate the piston smoothly at the end of its travel.

Where the Airtac SC50 Standard Cylinder SC50X1565 Is Used
Long-Reach Part Transfer
Pushes or pulls components across wide conveyor gaps or between distant workstations, using its 1565 mm stroke to bridge extended transfer points.
Vertical Door Actuation
Operates tall industrial doors or vertical lift gates, providing the necessary long linear motion with 982 N of force at standard 0.5 MPa air pressure.
Bulk Material Raking
Drives a rake or pusher plate across wide hoppers or sorting tables, handling bulk materials where a long, steady stroke is essential.
Is the Airtac SC50 Standard Cylinder SC50X1565 the Right Cylinder?
Choose the SC50 when your application needs around 982 N of force at standard plant pressure. If you require more force, stepping up to the SC63 bore provides 1559 N at the same 0.5 MPa. For a stroke this long, the 20 mm rod is susceptible to bending under side loads; you must guide the load externally with a rail system or use a guided cylinder to protect the rod bearings and seals. For a direct replacement, match the 50 mm bore, 1565 mm stroke, PT port thread, basic mounting, and the absence of a 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 SC50 Standard Cylinder SC50X1565 FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No, a stroke this long with a 20 mm rod creates a high risk of rod bending and premature seal wear if side loads are present. You must use an external linear guide or a guided cylinder assembly to constrain the load path and protect the cylinder.
