About the Airtac SC50 Standard Cylinder SC50X200FA
The AirTAC SC50X200FA is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 200 mm stroke, supplied with a front rectangular flange (FA) for rigid panel mounting. At 0.5 MPa air pressure it generates a push force of 982 N and a pull force of 825 N, rising to 1767 N push at the maximum operating pressure of 0.9 MPa.
This model uses a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 ports. The tie-rod construction includes an adjustable air cushion (21 mm length) at each end to decelerate the piston smoothly. The body length A is 150 mm, giving a total extended length of approximately 350 mm for this 200 mm stroke configuration.

Where the Airtac SC50 Standard Cylinder SC50X200FA Is Used
Clamping & Fixturing
The 982 N push force at 0.5 MPa provides ample clamping pressure for CNC fixtures, welding jigs, and assembly pallets where the front flange mount allows direct bolting to a vertical plate.
Part Stops & Gates
Extending a 20 mm rod 200 mm to stop or divert boxes on a conveyor line. The adjustable cushion absorbs impact energy, protecting the cylinder and the stopped product from shock.
Press & Forming Assist
Used as a low-cost linear actuator in small pneumatic presses or forming tools. The front flange mounting resists the thrust reaction force directly at the rod end, improving rigidity.
Is the Airtac SC50 Standard Cylinder SC50X200FA the Right Cylinder?
For applications needing slightly less force, stepping down to the SC40 bore delivers 628 N push at 0.5 MPa; for more force the SC63 bore provides 1559 N at the same pressure. The FA front flange mounting (accessory F-SC50FA) bolts directly to a machine panel or bracket and keeps the cylinder body cantilevered, which suits clean end-of-arm tooling or linear transfer stations.
When replacing an existing cylinder, match these five points exactly: 50 mm bore, 200 mm stroke, PT1/4 port thread, FA front flange mounting, and the absence of a built-in magnet. This SC model is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC50X200FA FAQ
At 0.7 MPa operating pressure the SC50 bore delivers a theoretical push force of 1374 N and a pull force of 825 N (the pull force figure is the 0.5 MPa value from the datasheet thrust table; for pull force at higher pressures, confirm from the full datasheet curve). The maximum push force at 0.9 MPa is 1767 N.
The FA front flange is designed for fixed, rigid mounting. If your application requires the cylinder body to pivot, select a rear clevis (CA or CB) or centre trunnion (TC) mounting variant instead. Using a flange mount in a pivoting application will side-load the rod and cause premature seal and bearing wear.
