About the Airtac SC50 Standard Cylinder SC50X225S
The AirTAC SC50X225S is a double-acting single-rod pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the 0.9 MPa maximum operating pressure). With a 50 mm bore and 225 mm stroke, it suits medium-force clamping, pressing, and material-transfer tasks where a compact tie-rod design is preferred.
This model includes the factory-installed -S magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly onto the barrel for piston-position feedback. The 20 mm diameter rod provides solid column strength, and the adjustable air cushion (21 mm) decelerates the piston smoothly at end of stroke. Body length A is 150 mm, giving an extended length of approximately 375 mm.

Where the Airtac SC50 Standard Cylinder SC50X225S Is Used
Conveyor Stop & Diverter
The 982 N push force at 0.5 MPa reliably stops or diverts medium-weight packages on a conveyor line. The built-in magnet enables end-of-stroke sensing for automated sortation control.
Clamping Fixture
Ideal for pneumatic clamping in machining or welding jigs, the 225 mm stroke provides ample retraction clearance for part loading, while the adjustable cushion prevents impact vibration.
Press-Fit Assembly
Delivers up to 1767 N at 0.9 MPa for light press-fit or staking operations. The tie-rod construction allows easy maintenance in high-cycle assembly stations.
Is the Airtac SC50 Standard Cylinder SC50X225S the Right Cylinder?
For lower force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa; for higher thrust, step up to the SC63 bore at 1559 N. The 225 mm stroke is within the 1200 mm maximum standard stroke for bore 50. When integrating this cylinder, ensure the five-point replacement match: 50 mm bore, 225 mm stroke, PT port thread, basic mount, and the -S magnet for sensor compatibility. At this stroke length, avoid unsupported side loads—if the rod must guide the load, pair the cylinder with an external linear guide or switch to a guided-cylinder configuration to prevent rod-bearing bending.
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 SC50X225S FAQ
At 0.5 MPa the cylinder produces 982 N extending (push) and 825 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to clamp directly onto the barrel tie-rods for contactless position detection.
