About the Airtac SC100 Standard Cylinder SC100X430
The SC100X430 is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa, scaling up to a powerful 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 430 mm stroke, this model is built for medium-to-heavy linear actuation tasks where a substantial force reserve is required.
This tie-rod cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 ports. The body length A is 188 mm, giving a total extended length of approximately 618 mm. Its 29 mm adjustable air cushion decelerates the piston smoothly at stroke ends, protecting end caps from impact damage.

Where the Airtac SC100 Standard Cylinder SC100X430 Is Used
Belt Tensioning & Roller Actuation
Applies consistent 3927 N force at 0.5 MPa for heavy-duty conveyor belt take-up systems, roller nip adjustments, and material diverters in aggregate or recycling plants.
Press & Clamping Fixtures
Generates up to 7068 N of clamping force at 0.9 MPa for holding large weldments, composite lay-up tools, or heavy woodworking panels during CNC routing and assembly.
Agricultural Gate & Chute Control
Operates heavy slide gates, seed/fertilizer chute diverters, and silo discharge doors. The 430 mm stroke provides the linear travel needed for wide openings in bulk handling.
Is the Airtac SC100 Standard Cylinder SC100X430 the Right Cylinder?
For applications needing slightly less force, the 80 mm bore SC80 series provides 2513 N at 0.5 MPa, while stepping up to the 125 mm bore SC125 yields 6136 N at the same pressure. Always match the bore, 430 mm stroke, PT1/2 port thread, and basic mounting configuration when replacing this cylinder.
At a 430 mm stroke, side-load forces can create a bending moment on the 25 mm rod. If the load is not guided externally, install a linear guide rail or rod-alignment coupler to prevent premature rod bearing and seal wear. For vertical or unsupported loads, consider an external guide system.
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 SC100X430 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, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X430 is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. Use a pilot-operated check valve or external rod lock for static load holding.
