About the Airtac SC100 Standard Cylinder SC100X450
The SC100X450 is a double-acting tie-rod cylinder delivering a substantial 3927 N push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 450 mm stroke, it uses a 25 mm diameter piston rod and PT1/2 ports, making it a robust actuator for medium-to-heavy linear motion tasks.
This model features a 29 mm adjustable pneumatic cushion at each end to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 188 mm, giving a total extended length of approximately 638 mm. As a genuine AirTAC SC series unit, it is built for reliable service in filtered compressed air systems up to 1.0 MPa.

Where the Airtac SC100 Standard Cylinder SC100X450 Is Used
Material Handling & Sorting
Provides the 3927 N push force needed to divert heavy packages or products on conveyor lines, operating reliably in dusty or busy industrial environments.
Press & Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding workpieces during machining, welding, or assembly, with adjustable cushioning for smooth operation.
Agricultural Equipment Actuation
Used for positioning gates, chutes, or hopper doors on farming machinery, where its 25 mm rod and tie-rod construction withstand tough outdoor conditions.
Is the Airtac SC100 Standard Cylinder SC100X450 the Right Cylinder?
Choose the SC100 when your application needs the force class of 3927 N at 0.5 MPa. If you need a more compact actuator with lower force, step down to the SC80 bore (2513 N at 0.5 MPa). For higher thrust, the SC125 provides 6136 N at the same pressure. This 450 mm stroke is within the standard range for the 100 mm bore, but always check for potential rod buckling or side loading on strokes over 300 mm; an external guide or guided cylinder is recommended if the load is not purely axial.
For a direct replacement, match these five points: 100 mm bore, 450 mm stroke, PT1/2 port thread, basic mounting (no brackets), and ensure the magnet option (-S) matches your sensor setup. This is a tie-rod cylinder 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 SC100X450 FAQ
At the standard operating pressure of 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 increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC series 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 rod can drift or drop. For load holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve in the circuit.
