About the Airtac SC100 Standard Cylinder SC100X420
The SC100X420 is a double-acting tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 420 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 body length A of 188 mm, resulting in a total extended length of approximately 608 mm. The adjustable pneumatic cushion at each end (29 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. As a genuine AirTAC SC series cylinder, it is built for reliable service in filtered air systems up to 1.0 MPa.

Where the Airtac SC100 Standard Cylinder SC100X420 Is Used
Pallet Stop & Transfer
Provides the high force needed to stop and transfer heavy pallets on conveyor lines, with the 420 mm stroke offering ample reach for cross-transfer mechanisms.
Waste Compaction
Ideal for small-to-medium balers and compactors, where the 7068 N force at 0.9 MPa compresses cardboard, plastics, or other recyclable materials into dense bales.
Heavy Part Clamping
Used in welding and assembly fixtures to securely clamp large fabrications. The adjustable cushion prevents vibration and part shifting at the end of the clamp stroke.
Is the Airtac SC100 Standard Cylinder SC100X420 the Right Cylinder?
Select the SC100X420 when your application needs a push force around 3927 N at standard plant pressure. If a lighter, more compact solution is acceptable, stepping down to an 80 mm bore (2513 N at 0.5 MPa) can reduce air consumption. For higher force requirements, the 125 mm bore provides 6136 N at the same pressure.
At a 420 mm stroke, the 25 mm rod is susceptible to bending under significant side loads. For this stroke length, ensure the load is guided externally on linear rails or consider a guided cylinder to protect the rod bearings and seals. For direct replacement, match the 100 mm bore, 420 mm stroke, PT1/2 port thread, basic mounting, and the absence of a magnet sensor option.
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 SC100X420 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum push force at the 0.9 MPa operating limit is 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No, the SC series is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston can drift or drop under load. To hold a position safely, you must add an external rod lock or a pilot-operated check valve.
