About the Airtac SC50 Standard Cylinder SC50X450SFB
The SC50X450SFB is a double-acting pneumatic cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa, making it a robust mid-range actuator for industrial automation. This model features a 20 mm diameter piston rod with an M16x1.5 thread and a 21 mm adjustable air cushion at each end to decelerate the piston smoothly.
With a 450 mm stroke, the total extended body length reaches approximately 600 mm. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for precise position feedback, while the rear rectangular flange (FB) provides a rigid, panel-mounted installation point.

Where the Airtac SC50 Standard Cylinder SC50X450SFB Is Used
Material Handling Gates
The 450 mm stroke and rear flange mount are ideal for actuating diverter gates or stops on conveyor lines, with sensor feedback confirming open/closed positions.
Clamping & Assembly Fixtures
Delivers consistent clamping force up to 1767 N for holding parts during welding or assembly, with the FB flange bolting securely to a machine frame.
Packaging & Palletizing
Pushes cartons or products onto pallets with a 450 mm reach. The magnetic piston enables end-of-stroke detection to sequence with other automation.
Is the Airtac SC50 Standard Cylinder SC50X450SFB the Right Cylinder?
The SC50 bore provides 982 N of push force at 0.5 MPa. If your application requires higher force, consider stepping up to the SC63 bore which delivers 1559 N at the same pressure. For lighter, more compact needs, the SC40 bore offers 628 N. This 450 mm stroke requires careful management of side loads; long unsupported rods are susceptible to bending. Use an external linear guide or ensure the load is purely axial to maximize seal and bearing life.
For a direct replacement, match five key points: 50 mm bore, 450 mm stroke, PT port thread, rear flange (FB) mounting with accessory F-SC50FB, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile and is not a direct interchange for that standard.
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 SC50X450SFB FAQ
At the standard operating pressure of 0.7 MPa, the push force is 1374 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N.
No. The SC50 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. To hold a load safely without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve.
