About the Airtac SC50 Standard Cylinder SC50X235
The AirTAC SC50X235 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 20 mm diameter piston rod and M16x1.5 rod thread. Its 235 mm stroke sits well within the 1200 mm maximum standard stroke for the 50 mm bore, making this a readily available standard configuration.
With a compact body length A of 150 mm and a 21 mm adjustable air cushion at each end, the SC50X235 decelerates the piston smoothly to reduce end-of-stroke impact. The cylinder uses PT1/4 ports and operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with its standard TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X235 Is Used
Packaging & Sorting Gates
The 235 mm stroke and 982 N push force at 0.5 MPa reliably actuate diverter gates and product stops on medium-speed packaging conveyors.
Clamping & Light Press Fixtures
Delivers consistent clamping force for woodworking jigs, drilling fixtures, and assembly stations where a 50 mm bore provides ample holding power.
Hopper & Chute Actuation
Operates slide gates and flow-control flaps on agricultural hoppers and material chutes, handling frequent cycling with filtered plant air.
Is the Airtac SC50 Standard Cylinder SC50X235 the Right Cylinder?
Choose the SC50X235 when your application needs roughly 1000 N of push force at standard plant air pressure. If you require more force, the SC63 bore steps up to 1559 N push at 0.5 MPa; for a lighter, more compact solution the SC40 bore provides 628 N. At 235 mm of stroke the rod remains well supported, but if your design introduces side loads or the stroke exceeds 300 mm, consider an external linear guide or a guided cylinder to protect the rod bearing from bending stresses.
For a direct replacement, match five points exactly: 50 mm bore, 235 mm stroke, PT port thread, the specific mounting accessory (this basic model uses no bracket), and the magnet option (this code has no built-in magnet). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X235 FAQ
At 0.7 MPa (7 bar) supply pressure, the SC50X235 generates 1374 N of push force and 825 N of pull force on the retract stroke, based on the 50 mm bore and 20 mm rod diameter.
No. The SC50X235 is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the directional valve is centred. If load holding is required, add a pilot-operated check valve or an external rod brake.
