About the Airtac SC50 Standard Cylinder SC50X540
The AirTAC SC50X540 is a double-acting tie-rod cylinder engineered for applications demanding a mid-range force output and an extended reach. With a 50 mm bore and a 540 mm stroke, this model generates a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod.
This specific stroke length exceeds the standard maximum of 1200 mm for the 50 mm bore, classifying it as a non-standard, made-to-order configuration. The unit features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, and its total extended body length is approximately 690 mm (150 mm body length A + 540 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X540 Is Used
Long-Reach Part Transfer
The 540 mm stroke moves components between distant conveyor lanes or workstations in automated assembly lines, using the 982 N push force at 0.5 MPa.
Vertical Door Actuation
Operates tall vertical safety doors or machine guarding panels, providing a controlled 1767 N maximum force at 0.9 MPa to lift and lower heavy shields smoothly.
Material Pusher & Divert
Ideal for diverting packages or pallets on wide roller beds, where the extended stroke is necessary to fully push items onto a perpendicular track.
Is the Airtac SC50 Standard Cylinder SC50X540 the Right Cylinder?
Select the SC50 bore when your application requires a push force around 982 N at standard plant pressure (0.5 MPa). If your load demands more force, stepping up to the SC63 bore provides 1559 N at the same pressure. For lighter, more compact needs, the SC40 bore delivers 628 N.
This 540 mm stroke requires careful management of side loads. Long, unsupported strokes on a 20 mm rod are susceptible to bending under lateral force. Always use an external guide rail or a guided cylinder assembly to absorb side loads and protect the rod bearing. For direct replacement, match five key points: bore (50 mm), stroke (540 mm), port thread (PT 1/4), basic mounting (no accessory), 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 SC50X540 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 reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
A stroke of 540 mm on a 20 mm rod is vulnerable to side-load bending. You must install an external linear guide or switch to a guided cylinder unit to absorb lateral forces. The adjustable air cushion only decelerates the piston at the stroke end and does not provide any mechanical support or locking.
