About the Airtac SC50 Standard Cylinder SC50X210SFB
The SC50X210SFB is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. Its 210 mm stroke is a non-standard length, extending the 20 mm diameter piston rod from a 150 mm body for a total extended length of approximately 360 mm.
This model is configured with a built-in magnet for direct mounting of CMSG/DMSG/EMSG sensors and an FB rear rectangular flange (F-SC50FB) for secure cap-end mounting. The adjustable air cushion at each end decelerates the piston smoothly, and the standard PT1/4 port threads ensure straightforward pneumatic connections.

Where the Airtac SC50 Standard Cylinder SC50X210SFB Is Used
Packaging Pusher
The 1767 N force at 0.9 MPa easily diverts cartons on a conveyor. The rear flange mount keeps the cylinder rigidly fixed against the push-off wall.
Clamping Fixture
With a built-in magnet for end-of-stroke sensing, this cylinder confirms clamp closure in automated welding or assembly jigs, ensuring cycle safety.
Material Gate Actuator
Controls a sliding gate on a hopper or chute. The adjustable cushion softens the stop at each end, reducing vibration on the 210 mm stroke.
Is the Airtac SC50 Standard Cylinder SC50X210SFB the Right Cylinder?
For applications requiring slightly less force, the 40 mm bore SC40 series provides 628 N at 0.5 MPa. If a longer standard stroke is needed, the SC50 bore supports up to 1200 mm as standard. This 210 mm non-standard stroke requires careful alignment; for strokes over 300 mm, an external guide is strongly recommended to protect the rod bearing from side loads.
To ensure a correct replacement, match five key points: the 50 mm bore, the 210 mm stroke, the PT1/4 port thread, the FB rear flange mounting accessory, and the -S magnet option for sensor compatibility.
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 SC50X210SFB FAQ
At 0.7 MPa operating pressure, the theoretical push force on the 50 mm bore is 1374 N. The pull force on the rod side is lower at 825 N due to the 20 mm rod area.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder. It is not dimensionally interchangeable. Only replace with another AirTAC SC50 tie-rod cylinder matching the same bore, stroke, port, mounting, and magnet options.
