About the Airtac SC50 Standard Cylinder SC50X150FA
The SC50X150FA is a 50 mm bore, 150 mm stroke double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration for mid-range automation tasks.
This model includes a front rectangular flange (FA) for secure panel or bulkhead mounting. The body length A is 150 mm, giving a compact extended length of 300 mm. It uses PT1/4 ports and operates on filtered air from -20 to +70 °C with standard TPU seals.

Where the Airtac SC50 Standard Cylinder SC50X150FA Is Used
Part Stops & Gates
The 150 mm stroke and 982 N force at 0.5 MPa reliably actuates part stops and diverter gates on conveyor lines, with the front flange providing rigid alignment.
Clamping & Pressing
Ideal for pneumatic clamping fixtures and light press operations. The adjustable cushion protects tooling at the end of the 150 mm stroke, ensuring repeatable, low-impact engagement.
Packaging Pushers
Pushes cartons or products into packaging stations. The FA flange allows the cylinder body to be mounted directly through a machine frame for a clean, space-saving installation.
Is the Airtac SC50 Standard Cylinder SC50X150FA the Right Cylinder?
Choose the SC50 for applications needing around 980 N at 0.5 MPa. If your load requires more force, step up to the SC63 bore which provides 1559 N at the same pressure. For lighter, faster moves, the SC40 bore offers 628 N.
For this 150 mm stroke, side loads are typically well-managed by the 20 mm rod and front flange support, but always align the load axially. To replace an existing cylinder, match five points: 50 mm bore, 150 mm stroke, PT1/4 port thread, FA front flange mount (F-SC50FA), and confirm the magnet requirement (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 SC50X150FA FAQ
At the standard operating pressure of 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.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and FA front flange mount.
