About the Airtac SC50 Standard Cylinder SC50X145
The AirTAC SC50X145 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), making it a robust mid-range actuator for general automation. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for the 145 mm stroke, while the compact body length of 150 mm plus stroke keeps the overall footprint efficient.
This model comes with the standard TPU seal package for a -20 to +70 °C operating range and PT1/4 threaded ports. The 145 mm stroke is a standard offering within the SC family, well-suited for clamping, pressing, and material-transfer tasks where consistent double-acting force is required.

Where the Airtac SC50 Standard Cylinder SC50X145 Is Used
Part Transfer & Sorting
The 145 mm stroke and 982 N push force reliably shift small to medium components between conveyor lanes or into sorting gates in packaging and assembly lines.
Clamping & Holding Fixtures
Delivers consistent double-acting force for pneumatic clamps and holding fixtures in machining or welding cells, with the adjustable cushion softening end-of-stroke impact.
Press & Forming Assist
Provides up to 1767 N at 0.9 MPa for light press-fit, staking, or forming operations where a compact tie-rod cylinder fits the machine envelope.
Is the Airtac SC50 Standard Cylinder SC50X145 the Right Cylinder?
Choose the SC50 bore when your application needs roughly 825–982 N of force at standard plant pressure. If you need more force, stepping up to the SC63 delivers 1559 N push at 0.5 MPa; for a lighter, more compact solution, the SC40 provides 628 N. At a 145 mm stroke, the rod bearing is well-supported for axial loads, but any significant side load requires an external guide or a guided cylinder to prevent rod bending and premature seal wear.
For a direct replacement, match five points: 50 mm bore, 145 mm stroke, PT1/4 port thread, the specific mounting accessory (this is a basic body, so order mounts like FA, FB, or LB separately using the F-SC50 prefix), and the magnet option (this model has no built-in magnet).
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 SC50X145 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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder of the same bore and stroke, so mounting dimensions and overall length are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT1/4 ports, and mounting style.
