About the Airtac SC50 Standard Cylinder SC50X200SFB
The AirTAC SC50X200SFB is a double-acting single-rod pneumatic cylinder delivering a push force of 982 N at 0.5 MPa (1374 N at 0.7 MPa). Its 200 mm stroke suits medium-reach clamping and pressing tasks where consistent linear motion is required.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear rectangular flange (FB, part F-SC50FB) for rigid end-face mounting. The 20 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration, while the PT1/4 port supplies standard flow.

Where the Airtac SC50 Standard Cylinder SC50X200SFB Is Used
Part Stops & Gates
The 200 mm stroke and rear flange mount allow the cylinder to be fixed at the end of a conveyor line, extending a stop pin to halt or release pallets with 982 N of holding force.
Jig & Fixture Clamping
With a built-in magnet for end-of-stroke sensing, this cylinder confirms clamp engagement in automated machining fixtures, preventing cycle starts on unclamped parts.
Press-Fit Assembly
Generates up to 1767 N at 0.9 MPa for pressing bushings or bearings into housings. The rear flange absorbs the reaction force directly into the machine frame.
Is the Airtac SC50 Standard Cylinder SC50X200SFB the Right Cylinder?
For higher force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, more compact actuator, the SC40 offers 628 N. The rear flange (FB) secures the cylinder from the cap end, ideal when the rod must extend freely into a fixture.
When replacing, match five points: 50 mm bore, 200 mm stroke, PT1/4 port thread, FB rear flange mounting, and the -S magnet for sensor compatibility. This ensures drop-in interchangeability with an existing AirTAC SC tie-rod cylinder.

- ✓ 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 SC50X200SFB FAQ
At 0.7 MPa operating pressure, the push force is 1374 N. The maximum push force at 0.9 MPa is 1767 N. Always size the cylinder based on the available plant air pressure.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the barrel for contactless position detection.
