About the Airtac SC100 Standard Cylinder SC100X300
The AirTAC SC100X300 is a double-acting tie-rod cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 300 mm stroke, it features a 25 mm diameter piston rod, M20x1.5 rod thread, and PT1/2 ports for robust pneumatic connections.
Its adjustable air cushion (29 mm length) decelerates the piston smoothly at end-of-stroke, reducing impact and noise. The body length A is 188 mm, giving a total extended length of approximately 488 mm. This genuine AirTAC cylinder is built for demanding industrial tasks requiring high force over a moderate stroke.

Where the Airtac SC100 Standard Cylinder SC100X300 Is Used
Heavy Part Transfer
Moves large components or sub-assemblies between conveyor lines, using 3927 N of force at 0.5 MPa to reliably shift heavy pallets.
Industrial Compaction
Drives a compaction plate in waste or recycling equipment, leveraging up to 7068 N of force at 0.9 MPa to densify materials.
Clamping & Fixturing
Provides powerful, consistent clamping for large weldments or machined parts, holding them securely during automated processing.
Is the Airtac SC100 Standard Cylinder SC100X300 the Right Cylinder?
For applications needing more force, consider stepping up to the SC125 series (6136 N at 0.5 MPa). If lower force suffices, the SC80 provides 2513 N. At 300 mm stroke, side-load management is critical—never subject the 25 mm rod to direct lateral forces without an external guide or linear bearing, as bending moments can damage the rod bearing and seals. When replacing, match bore, stroke, PT port thread, basic mounting, and absence of magnet exactly to ensure drop-in compatibility.
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 SC100X300 FAQ
At the standard operating pressure of 0.7 MPa, the push force is 5497 N. At the maximum operating pressure of 0.9 MPa, it reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. As a standard double-acting cylinder, the SC100X300 will drift or drop if pressure is exhausted. For load-holding, you must add a pilot-operated check valve or an external mechanical rod lock.
