About the Airtac SC50 Standard Cylinder SC50X45S
The SC50X45S is a double-acting tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 45 mm stroke and a 20 mm diameter piston rod, it is well-suited for short-throw clamping, ejecting, and sorting tasks where a compact installed length is required.
This model features a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly onto the barrel for precise, non-contact position sensing. The standard TPU seals provide a reliable operating temperature range of -20 to +70 °C, and the PT1/4 port threads ensure straightforward pneumatic connection.

Where the Airtac SC50 Standard Cylinder SC50X45S Is Used
Sensor-Monitored Clamping
The built-in magnet and 982 N clamping force make this cylinder ideal for automated workholding fixtures where control systems require end-of-stroke confirmation via barrel-mounted sensors.
Short-Stroke Part Stops
Deploy the SC50X45S as a pneumatic gate or part stop on conveyor lines. The 45 mm stroke provides crisp actuation to separate or align components moving down the line.
Light Assembly Pressing
With 1767 N of force available at 0.9 MPa, this cylinder can handle press-fit insertions for small bearings, bushings, or dowel pins in benchtop assembly cells.
Is the Airtac SC50 Standard Cylinder SC50X45S the Right Cylinder?
When sizing, step up to a 63 mm bore if you need more than 1559 N of push force at 0.5 MPa, or down to a 40 mm bore if 628 N is sufficient and a lighter, more compact cylinder is preferred. The 45 mm stroke is a standard length within the SC50 series.
For replacement, match five key points: 50 mm bore, 45 mm stroke, PT port thread, the basic mounting style, and the built-in magnet (-S). This ensures the sensor brackets and existing plumbing align correctly. If the application involves any side loading, even on this short stroke, an external guide rail is recommended to protect the rod bearing from premature wear.
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 SC50X45S 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 increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet, which is required for mounting CMSG, DMSG, or EMSG series sensors directly onto the cylinder barrel for contactless position detection.
