About the Airtac SC100 Standard Cylinder SC100X400SFA
The SC100X400SFA delivers 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), making it a workhorse for medium-to-heavy pneumatic tasks. Its 400 mm stroke is paired with a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end, providing smooth deceleration for moving sizeable payloads.
This configuration includes a built-in magnet (-S suffix) for easy mounting of CMSG/DMSG/EMSG sensors, and an FA front rectangular flange (F-SC100FA) for secure panel or bulkhead mounting. The body length A is 188 mm, giving a total extended length of approximately 588 mm.

Where the Airtac SC100 Standard Cylinder SC100X400SFA Is Used
Pallet Stop & Lift
The 400 mm stroke and 3927 N push force at 0.5 MPa are ideal for raising or stopping heavy pallets on a conveyor line, with sensors confirming position via the built-in magnet.
Press-Fit Assembly
Delivers up to 7068 N at 0.9 MPa for pressing bushings or bearings into housings. The front flange mount provides a rigid, stationary platform for the pressing operation.
Baler Compaction
Provides the sustained force needed for compacting recyclable materials in a small baler. The adjustable cushion manages the impact at the end of the 400 mm compaction stroke.
Is the Airtac SC100 Standard Cylinder SC100X400SFA the Right Cylinder?
Choose the SC100 when your application needs roughly 4000 N of force at standard plant pressure. If you need more, the SC125 delivers 6136 N at 0.5 MPa; for a more compact solution, the SC80 provides 2513 N. This 400 mm stroke is within the standard range, but the long rod extension demands attention to side loads—always guide the load externally or use a guided cylinder to protect the rod bearing from bending moments.
For a direct replacement, match five points: 100 mm bore, 400 mm stroke, PT port thread, FA front flange mounting, and the -S magnet for sensor compatibility. This tie-rod cylinder is not an ISO 15552 profile and will not interchange with those dimensions.
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 SC100X400SFA FAQ
At 0.5 MPa, 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 reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X400SFA is a double-acting cylinder and will drift or drop if pressure is exhausted. The adjustable air cushion only decelerates the piston at stroke end; it is not a lock. For load holding without pressure, you must add an external rod brake or a pilot-operated check valve.
