About the Airtac SC100 Standard Cylinder SC100X670
The SC100X670 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 670 mm stroke. At 0.5 MPa it generates 3927 N pushing force and 3681 N pulling force, rising to a substantial 7068 N push at the 0.9 MPa maximum operating pressure, making it suitable for medium-to-heavy linear actuation tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT1/2 ports. The 670 mm stroke is within the 1500 mm maximum standard stroke for bore 100, and the cylinder body length A is 188 mm, giving a total extended length of approximately 858 mm. An adjustable air cushion at each end decelerates the piston over a 29 mm cushion length to reduce end-of-stroke impact.

Where the Airtac SC100 Standard Cylinder SC100X670 Is Used
Pallet Stop & Lift
The 3927 N push force at 0.5 MPa and 670 mm stroke positions this cylinder for raising or stopping heavy pallets on conveyor lines, where a robust tie-rod design handles repetitive impact.
Press-Frame Ejection
With 7068 N of force available at 0.9 MPa, the SC100X670 can eject formed parts from a press tool or mould, using the full 670 mm travel to clear the die area completely.
Diverter Gate Actuation
The long 670 mm stroke and high force suit large material-handling diverter gates, pushing product flow from one chute to another with the adjustable cushion softening the shift at each end.
Is the Airtac SC100 Standard Cylinder SC100X670 the Right Cylinder?
Choose the SC100 bore when your application needs between roughly 3900 N and 7000 N of push force from standard 0.5–0.9 MPa shop air. If your load is lighter, stepping down to an SC80 bore (2513 N push at 0.5 MPa) can reduce air consumption and physical size. For heavier loads, the SC125 bore provides 6136 N at 0.5 MPa.
At 670 mm stroke, the unsupported rod length is significant. Any side load or off-centre mounting will create a bending moment on the rod bearing; use an external linear guide or a guided cylinder to absorb transverse forces and protect the rod and seals. For replacement, match five points: 100 mm bore, 670 mm stroke, PT1/2 port thread, basic mount (no accessory bracket), and no magnet.
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 SC100X670 FAQ
At the standard 0.5 MPa operating pressure, push force is 3927 N and pull force is 3681 N. At 0.7 MPa, push rises to 5497 N. The maximum push force at the 0.9 MPa operating limit is 7068 N (theoretical max at 1.0 MPa is 801 kgf).
No, the SC100X670 is not designed for unguided side loads. The 25 mm rod extended 670 mm is vulnerable to bending under transverse force. Always couple the rod to an external linear guide rail or use a guided cylinder variant to absorb side loads and prevent premature rod bearing and seal wear.
