About the Airtac SC100 Standard Cylinder SC100X400CB
The AirTAC SC100X400CB is a double-acting tie-rod cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. Its 100 mm bore, 25 mm diameter piston rod, and 400 mm stroke make it a strong linear actuator for medium-to-heavy industrial tasks.
This model features a rear double clevis (CB) mount, part F-SC100CB, allowing the cylinder body to pivot during operation and simplifying installation in articulated linkages. The adjustable pneumatic cushion (29 mm length) decelerates the piston smoothly at stroke end, while the standard PT1/2 port threads ensure straightforward air-line connection.

Where the Airtac SC100 Standard Cylinder SC100X400CB Is Used
Agricultural Equipment Actuation
Operates pivot arms, chute diverters, and tailgate mechanisms on harvesters and spreaders. The CB clevis mount handles the constant pivoting motion, while the 400 mm stroke provides the necessary reach for large implements.
Conveyor Diverter Gates
Pushes heavy diverter gates on aggregate or recycling conveyors. The 3927 N force at 0.5 MPa shifts stubborn material flows reliably, and the adjustable cushion prevents hard stops that could shake the conveyor structure.
Heavy Press Feed Systems
Advances steel blanks or heavy components into stamping presses. The 7068 N maximum thrust at 0.9 MPa overcomes friction in roller beds, and the rear clevis mount absorbs misalignment as the tooling cycles.
Is the Airtac SC100 Standard Cylinder SC100X400CB the Right Cylinder?
Choose the SC100 when your application needs roughly 3927 N of push force at standard plant pressure. If you require more force, stepping up to the SC125 bore provides 6136 N at 0.5 MPa; for a lighter, more compact solution, the SC80 delivers 2513 N. This 400 mm stroke places moderate bending stress on the 25 mm rod—if the load is not guided externally, side forces can damage the rod bearing and seal, so consider adding an external guide rail or switching to a guided cylinder for long-stroke applications.
For a direct replacement, match five key points: 100 mm bore, 400 mm stroke, PT port thread, CB rear double clevis mounting, and the absence of a magnet. This cylinder is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile 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 SC100X400CB FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, push force increases to 5497 N. The maximum operating pressure of 0.9 MPa yields 7068 N of push force. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X400CB is a double-acting pneumatic cylinder and will drift or drop if air pressure is lost or the directional valve is centered. To hold a load or maintain position without live pressure, you must add an external rod lock, a mechanical brake, or a pilot-operated check valve in the circuit.
