About the Airtac SC50 Standard Cylinder SC50X4
The AirTAC SC50X4 is a compact-stroke double-acting pneumatic cylinder built for precise short-travel positioning. With a 50 mm bore and just 4 mm of stroke, it delivers a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa), making it ideal for clamping, ejecting, or stamping tasks where space is tight.
This tie-rod cylinder uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The body length A is 150 mm, giving a total extended length of approximately 154 mm. It features an adjustable air cushion (21 mm long) to decelerate the piston quietly at end of travel.

Where the Airtac SC50 Standard Cylinder SC50X4 Is Used
Precision Clamping
The 4 mm stroke and 982 N force at 0.5 MPa make this cylinder perfect for short-throw workpiece clamping in CNC fixtures and assembly jigs.
Micro-Stamping & Marking
Delivers a controlled, high-force impact over a tiny travel distance for part marking, riveting, or light stamping operations.
Part Ejection & Stopping
Ideal as a pneumatic stop or ejector on conveyor lines where a brief, powerful push is needed to divert or separate components.
Is the Airtac SC50 Standard Cylinder SC50X4 the Right Cylinder?
Choose the SC50 bore when you need roughly 1000 N of push force at standard plant pressure. If your application requires more force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N push at 0.5 MPa. For a direct replacement, match bore (50 mm), stroke (4 mm), port thread (PT), and mounting style — this basic model has no magnet or accessory bracket.
Even on short-stroke cylinders, ensure the rod is aligned axially with the load. Any side force on the 20 mm rod can accelerate bearing wear and reduce seal life.
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 SC50X4 FAQ
At 0.7 MPa (7 bar) supply pressure, the SC50X4 generates 1374 N of push force on the outstroke and 825 N of pull force on the return stroke.
This specific model (SC50X4) does not include the -S magnet option, so standard barrel-mounted reed or solid-state sensors cannot be used. To add sensor capability, order the SC50X4-S variant, which includes a built-in magnet compatible with CMSG/DMSG/EMSG sensors.
