About the Airtac SC100 Standard Cylinder SC100X400
The SC100X400 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 400 mm stroke. At 0.5 MPa it generates 3927 N of push force, rising to 7068 N at the maximum operating pressure of 0.9 MPa, placing it in the 4-kN class for medium-heavy linear tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT1/2 ports. The total body length A is 188 mm, giving an extended length of approximately 588 mm. An adjustable air cushion softens end-of-stroke impact over a 29 mm cushion length, protecting the end caps during high-cycle operation.

Where the Airtac SC100 Standard Cylinder SC100X400 Is Used
Pallet Stop & Lift Gates
The 400 mm stroke and 3927 N push force at 0.5 MPa allow the SC100X400 to raise or stop heavy pallets on gravity roller conveyors, providing a robust end-of-line gate actuator.
Press-Fit & Clamping Fixtures
Delivering up to 7068 N at 0.9 MPa, this cylinder suits pneumatic press-fit stations and heavy-duty welding jigs where consistent clamping force is critical for part alignment.
Diverter & Pusher Arms
With 400 mm of travel, the SC100X400 can push cartons or totes off a main conveyor line onto a spur. The adjustable cushion ensures quiet, low-impact operation at the end of each divert cycle.
Is the Airtac SC100 Standard Cylinder SC100X400 the Right Cylinder?
Choose the SC100X400 when your application needs roughly 3900 N of push force at standard plant pressure. If the load is lighter, stepping down to the 80 mm bore (2513 N at 0.5 MPa) saves space and air consumption. For heavier loads, the 125 mm bore delivers 6136 N at the same pressure.
At a 400 mm stroke, side-loading on the 25 mm rod must be managed. Always guide the load externally with rails or rods—do not let the cylinder rod carry bending moments. When replacing an existing unit, match five points: 100 mm bore, 400 mm stroke, PT1/2 port thread, basic (no bracket) mounting, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC100 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 SC100 Standard Cylinder SC100X400 FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa push rises to 5497 N, and at the maximum operating pressure of 0.9 MPa it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X400 is a double-acting cylinder and does not lock or hold position when air is exhausted or the directional valve is centred. If the application requires load holding during a power loss or E-stop, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
