About the Airtac SC50 Standard Cylinder SC50X45N
The AirTAC SC50X45N is a compact double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 45 mm stroke suits short linear actuation tasks, with a 20 mm diameter piston rod providing excellent rigidity for push/pull operations.
This model features NBR (nitrile) seals as standard, offering reliable sealing for general industrial air service. The PT1/4 port and M16x1.5 rod thread ensure straightforward pneumatic connection, while the adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length.

Where the Airtac SC50 Standard Cylinder SC50X45N Is Used
Part Stops & Gates
The 982 N push force at 0.5 MPa is ideal for stopping light packages or actuating small diverter gates on conveyor lines, where the 45 mm stroke provides a crisp, defined movement.
Clamping & Fixturing
Use the SC50X45N in jigs and fixtures for workpiece clamping. The short 45 mm stroke and 20 mm rod offer stable, repeatable holding force without excessive overtravel.
Valve Actuation
Reliable actuation of small ball or butterfly valves in processing lines. The NBR seals handle standard air, and the adjustable cushion prevents hard stops during fast cycling.
Is the Airtac SC50 Standard Cylinder SC50X45N the Right Cylinder?
Choose the SC50X45N for applications needing around 1000 N of force at standard shop air pressure. If your load requires more thrust, step up to the SC63 bore (1559 N at 0.5 MPa); for lighter, faster cycling, the SC40 bore (628 N) may be a better fit. Always confirm that the 45 mm stroke provides sufficient working travel without requiring external stops.
For replacement, match these five points: 50 mm bore, 45 mm stroke, PT port thread, basic (no accessory) mounting, and NBR seal material. This cylinder is not dimensionally interchangeable with ISO 15552 profiles—only replace with another AirTAC SC tie-rod cylinder of the same specifications.
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 SC50X45N FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides 982 N pushing force and 825 N pulling force. At 0.7 MPa, the push force increases to 1374 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so mounting dimensions and overall length will not match. You must replace it with another AirTAC SC50 tie-rod cylinder or verify mounting compatibility carefully.
