About the Airtac SC50 Standard Cylinder SC50X45
The SC50X45 is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 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 footprint is required.
This tie-rod cylinder features a 150 mm body length (A dimension) and an adjustable air cushion of 21 mm to decelerate the piston smoothly. It operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with its standard TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X45 Is Used
Short-Stroke Clamping
The 45 mm stroke and 982 N force at 0.5 MPa make it ideal for pneumatic clamping fixtures in woodworking or metal fabrication, holding workpieces securely during machining.
Part Ejection
Use the SC50X45 for ejecting parts from injection molds or stamping dies. Its rapid 30-800 mm/s speed range and compact body length suit high-cycle automation cells.
Diverter Gate Actuation
Deploy this cylinder to actuate small diverter gates on packaging conveyors. The 20 mm rod provides ample rigidity for the short, direct-acting stroke.
Is the Airtac SC50 Standard Cylinder SC50X45 the Right Cylinder?
For applications needing slightly more force, consider stepping up to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a lighter, more compact unit is acceptable, the 40 mm bore SC40 offers 628 N. The 45 mm stroke is a standard length for the SC50.
When replacing an existing cylinder, match five key points: 50 mm bore, 45 mm stroke, PT1/4 port thread, basic (no) mounting accessories, and the absence of a magnet. This ensures a direct dimensional and performance swap with another AirTAC SC50 tie-rod unit.
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 SC50X45 FAQ
At 0.7 MPa operating pressure, the SC50X45 produces a push force of 1374 N. The pull force at the same pressure is 825 N, accounting for the 20 mm rod diameter.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so the mounting dimensions are not interchangeable. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching port type and stroke.
