About the Airtac SC50 Standard Cylinder SC50X440
The AirTAC SC50X440 is a double-acting single-rod pneumatic cylinder delivering 982 N of push force 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 440 mm stroke, this model is built for medium-duty linear tasks where a compact tie-rod design is preferred over bulkier ISO 15552 profiles.
This cylinder uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. The body length A is 150 mm, giving an approximate extended length of 590 mm. Standard TPU seals provide a reliable operating range of -20 to +70 °C.

Where the Airtac SC50 Standard Cylinder SC50X440 Is Used
Material Stop & Transfer
Provides the 1374 N push at 0.7 MPa needed to stop or divert medium-weight packages on a conveyor line, with the 440 mm stroke reaching across wide belt sections.
Clamping & Pressing
Delivers up to 1767 N of clamping force at 0.9 MPa for holding workpieces during assembly, welding, or light pressing operations in a manufacturing cell.
Gate & Hopper Actuation
The 440 mm stroke and robust tie-rod construction suit sliding gate or hopper door control on agricultural equipment, handling dusty conditions with standard NBR/TPU seals.
Is the Airtac SC50 Standard Cylinder SC50X440 the Right Cylinder?
For applications needing more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at 0.5 MPa. If space is the priority, the 40 mm bore (SC40 series) offers 628 N at the same pressure. Always match the exact bore, stroke, PT1/4 port thread, and mounting accessory when replacing an existing unit.
At a 440 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 SC50X440 is a basic configuration with no built-in magnet, no mounting accessories, standard TPU seals, and PT threads.
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 SC50X440 FAQ
At the standard 0.7 MPa operating pressure, the push force is 1374 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N.
No. The SC50X440 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding, you must add a pilot-operated check valve or an external mechanical rod lock.
