About the Airtac SC50 Standard Cylinder SC50X175
The SC50X175 is a 50 mm bore, 175 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. Operating at a standard 0.5 MPa air pressure, it provides a theoretical push force of 982 N, making it a capable mid-range actuator for general industrial automation tasks.
This model features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The total body length A is 150 mm, resulting in an extended length of approximately 325 mm. It includes an adjustable pneumatic cushion (21 mm long) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact.

Where the Airtac SC50 Standard Cylinder SC50X175 Is Used
Material Sorting Gates
Provides the 982 N push force needed to actuate diverter gates on packaging and logistics conveyors, reliably directing products down different lanes.
Clamping & Light Pressing
Ideal for jig and fixture clamping in machining or assembly cells, where the 175 mm stroke offers ample reach and the 20 mm rod resists bending under axial loads.
General Machine Actuation
A versatile workhorse for pushing, pulling, and lifting motions in special-purpose machinery, offering easy integration with standard PT1/4 pneumatic fittings.
Is the Airtac SC50 Standard Cylinder SC50X175 the Right Cylinder?
Choose the SC50X175 for applications needing a reliable 982 N push at standard line pressure. If your load requires a higher force margin, stepping up to the 63 mm bore (SC63 series) provides 1559 N at the same 0.5 MPa. For lighter, more compact needs, the 40 mm bore delivers 628 N.
When replacing an existing cylinder, ensure a 5-point match: 50 mm bore, 175 mm stroke, PT1/4 port thread, basic (no) mounting accessories, and no built-in magnet. This is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a direct drop-in replacement for that standard.
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 SC50X175 FAQ
At 0.5 MPa, the theoretical 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 at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (150 mm for the 50 bore) than a comparable ISO 15552 profile cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port, and mounting specifications.
