About the Airtac SC50 Standard Cylinder SC50X265
The AirTAC SC50X265 is a double-acting tie-rod cylinder with a 50 mm bore and a 265 mm non-standard stroke, providing a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa. The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure reliable deceleration, while the compact 150 mm body length A keeps the overall extended length to 415 mm.
This cylinder uses a PT1/4 port and an M16x1.5 rod thread, operating on filtered air from 0.15 to 1.0 MPa. With a standard TPU seal, it works reliably in temperatures from -20 to +70 °C. As a genuine AirTAC component, it is built for consistent performance in industrial automation tasks.

Where the Airtac SC50 Standard Cylinder SC50X265 Is Used
Material Sorting Gates
The 265 mm stroke and 1374 N push force at 0.7 MPa reliably actuates diverter gates on medium-duty conveyor lines, directing packages or parts between lanes.
Clamping & Fixturing
Delivers 1767 N of clamping force at 0.9 MPa for holding workpieces during machining or welding, with the 21 mm cushion absorbing shock at the end of the 265 mm travel.
Press & Assembly Tools
Ideal for light-duty pressing or component insertion tasks, where the 50 mm bore provides a balanced combination of force and speed for repetitive assembly operations.
Is the Airtac SC50 Standard Cylinder SC50X265 the Right Cylinder?
For applications needing slightly less force, the 40 mm bore SC40 series offers 879 N at 0.7 MPa. If higher force is required, stepping up to the 63 mm bore provides 2182 N at the same pressure. Always match bore, stroke, PT1/4 port thread, and basic mounting when replacing an existing cylinder.
At a 265 mm stroke, the 20 mm rod is robust for axial loads, but any significant side load requires an external guide or a guided cylinder to prevent rod bending and premature bearing wear. The non-standard stroke length is a made-to-order item.
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 SC50X265 FAQ
The theoretical push force is 982 N at 0.5 MPa, 1374 N at 0.7 MPa, and 1767 N at the maximum operating pressure of 0.9 MPa. The pull force on the return stroke is 825 N at 0.5 MPa due to the 20 mm rod area.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. For a direct replacement, match the 50 mm bore, 265 mm stroke, PT1/4 ports, and basic mounting of another AirTAC SC cylinder.
