About the Airtac SC50 Standard Cylinder SC50X400FA
The SC50X400FA is a double-acting pneumatic cylinder delivering 982 N of push force and 825 N of pull force at 0.5 MPa (1767 N push at 0.9 MPa). Its 50 mm bore and 400 mm stroke suit medium-force linear tasks where a rigid front-flange mounting face is needed.
This model comes with an FA front rectangular flange (F-SC50FA) for secure panel or bulkhead mounting. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration. Ports are PT1/4, and the total extended body length is approximately 550 mm (body length A 150 mm + 400 mm stroke).

Where the Airtac SC50 Standard Cylinder SC50X400FA Is Used
Panel-Mounted Clamping
The FA front flange bolts directly to a machine panel, making this cylinder ideal for jig and fixture clamping where the body must be rigidly fixed at the rod end.
Part Stops & Gates
Delivers 982 N at standard shop air to raise and lower part stops or divert gates on conveyor lines, with adjustable cushioning to reduce impact noise.
Press & Assembly Tools
Used in small pneumatic presses or assembly stations requiring a 400 mm working stroke and consistent push force for inserting, staking, or forming operations.
Is the Airtac SC50 Standard Cylinder SC50X400FA the Right Cylinder?
Choose the SC50X400FA when 982 N at 0.5 MPa meets your force requirement. If you need more force, step up to the SC63 bore (1559 N push at 0.5 MPa); for a lighter, more compact solution, the SC40 bore provides 628 N. At 400 mm stroke, ensure side loads are minimal or use an external guide—long unsupported rods can bend under lateral force.
For direct replacement, match five points: 50 mm bore, 400 mm stroke, PT1/4 ports, FA front flange mount, and no magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC50 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 SC50X400FA FAQ
At 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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
The SC50X400FA is supplied with a front flange (FA). If your application requires a pivoting mount, order the SC50X400TC model which includes the centre trunnion and TCM1 bracket. Mounting accessories are not field-interchangeable on the same cylinder body without disassembly.
