About the Airtac SC50 Standard Cylinder SC50X175S
The SC50X175S is a 50 mm bore double-acting tie-rod cylinder with a 175 mm stroke, pre-fitted with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors. At 0.5 MPa it provides 982 N of push force and 825 N on the pull stroke, making it a capable mid-range actuator for automated equipment.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The adjustable air cushion absorbs 21 mm of travel at each end, while the TPU seals support an operating temperature range of -20 to +70 °C. The compact body length A is 150 mm, giving a total extended length of 325 mm.

Where the Airtac SC50 Standard Cylinder SC50X175S Is Used
Part Staging & Stops
The 175 mm stroke and 825 N pull force reliably actuate part stops and diverter gates on packaging and assembly conveyors, with the magnetic piston enabling precise end-of-stroke detection.
Clamping & Press-Fixturing
Delivers 1767 N of clamping force at the maximum 0.9 MPa operating pressure, ideal for holding workpieces during welding, gluing, or light machining operations.
Sortation Pushers
The 50 mm bore provides a balanced force-to-speed ratio for ejector arms and pushers in logistics sortation, where the built-in magnet allows for multi-position sensing along the stroke.
Is the Airtac SC50 Standard Cylinder SC50X175S the Right Cylinder?
Choose the SC50X175S when your application needs roughly 980 N of force at standard plant air pressure. If you require more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N at the same 0.5 MPa, while stepping down to the 40 mm bore offers 628 N for lighter, faster-cycling tasks. The built-in magnet eliminates the need for external sensor brackets, allowing clean, tool-free mounting of reed or solid-state switches along the tie-rod barrel.
For a direct replacement, match five points: 50 mm bore, 175 mm stroke, PT1/4 ports, the built-in magnet (-S suffix), and the basic mounting style. This cylinder is not an ISO 15552 profile unit; it is a genuine AirTAC SC tie-rod design and will only directly interchange with another AirTAC SC50 cylinder of identical configuration.
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 SC50X175S FAQ
At 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 reaches 1767 N. The theoretical maximum force 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 be clamped directly onto the cylinder's tie-rod barrel without any additional brackets.
