About the Airtac SC50 Standard Cylinder SC50X485
The SC50X485 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 485 mm stroke. It generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it suitable for medium-duty linear tasks.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The cylinder body length (dimension A) is 150 mm, and the total extended length is approximately 635 mm. It includes an adjustable air cushion with a 21 mm cushion length to decelerate the piston smoothly at stroke ends.

Where the Airtac SC50 Standard Cylinder SC50X485 Is Used
Material Stops and Gates
Provides the 982 N force needed to raise or lower product stops on a packaging conveyor line, reliably halting totes at a sorting station.
Clamping and Fixturing
Applies consistent clamping pressure to hold medium-sized workpieces during CNC machining or welding, with the 485 mm stroke clearing the fixture for easy loading.
Bin Diverter Actuation
Pushes a diverter chute on a gravity conveyor, directing boxes to the correct lane based on barcode data, leveraging the long stroke for full chute articulation.
Is the Airtac SC50 Standard Cylinder SC50X485 the Right Cylinder?
For applications needing slightly less force, consider the SC40 series which provides 628 N of push at 0.5 MPa. If higher force is required, stepping up to the SC63 bore delivers 1559 N at the same pressure. Always ensure the mounting and port threads match your existing setup when replacing a cylinder.
At a 485 mm stroke, the piston rod is extended significantly. Be mindful of side loads, which can cause rod deflection and bearing wear. For applications with off-centre loads, use an external guide rail or a guided cylinder to protect the rod and seals from bending stress.
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 SC50X485 FAQ
At the standard operating pressure of 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.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable with ISO 15552 profiles. It directly replaces another AirTAC SC50 cylinder with the same stroke, port thread, and mounting.
