About the Airtac SC100 Standard Cylinder SC100X400FA
The SC100X400FA is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at 0.9 MPa, making it a robust linear actuator for medium-to-heavy industrial tasks. This model features a 25 mm diameter piston rod, a 29 mm adjustable air cushion, and a front rectangular flange (FA) for secure panel or bulkhead mounting.
With a 400 mm stroke and a compact tie-rod body (body length A = 188 mm), this genuine AirTAC cylinder is well-suited for press tooling, clamping, and material handling where a rigid, face-mounted actuator is required. The standard PT1/2 ports and TPU seals ensure reliable operation in normal industrial environments from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X400FA Is Used
Heavy Press Tooling
Delivers up to 7068 N of force at 0.9 MPa for punching, stamping, and die-casting operations where a rigid front-flange mount is essential.
Pallet Stop & Transfer
The 400 mm stroke and 3927 N push force at 0.5 MPa reliably actuates heavy pallet stops and transfer mechanisms on conveyor lines.
Clamping & Fixturing
Provides strong, consistent clamping force for welding fixtures and assembly jigs, with the FA flange allowing direct mounting to machine frames.
Is the Airtac SC100 Standard Cylinder SC100X400FA the Right Cylinder?
Choose the SC100 bore when your application needs between 3927 N (push at 0.5 MPa) and 7068 N (push at 0.9 MPa). If your force requirement is lower, stepping down to an SC80 bore provides 2513 N at 0.5 MPa in a smaller envelope. For higher forces, the SC125 bore delivers 6136 N at 0.5 MPa. This model uses a front flange mount (FA, part F-SC100FA) for direct end-face attachment.
For this 400 mm stroke, ensure the load is guided and side forces are minimized; long unsupported strokes can cause rod bending and premature bearing wear. For exact drop-in replacement, match a cylinder with the same 100 mm bore, 400 mm stroke, PT1/2 port thread, FA front flange mounting, and no magnet.
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 SC100 Standard Cylinder SC100X400FA FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
It can replace another tie-rod cylinder if five points match: 100 mm bore, 400 mm stroke, PT1/2 port thread, FA front flange mounting (part F-SC100FA), and no built-in magnet. This is not an ISO 15552 cylinder and will not interchange with ISO 15552 profile cylinders.
