About the Airtac SC100 Standard Cylinder SC100X225LB
The AirTAC SC100X225LB is a double-acting tie-rod cylinder equipped with an LB foot mounting for secure surface installation. With a 100 mm bore and 225 mm stroke, it generates a push force of 3927 N at 0.5 MPa, scaling up to a substantial 7068 N at the maximum operating pressure of 0.9 MPa.
This model features a 25 mm diameter piston rod and an M20x1.5 rod thread, paired with a PT1/2 port. The adjustable air cushion provides a 29 mm deceleration zone at each end of the stroke, ensuring smooth stops under heavy loads. The body length A is 188 mm, giving a total extended length of approximately 413 mm.

Where the Airtac SC100 Standard Cylinder SC100X225LB Is Used
Belt Tensioning & Conveyor Stops
The 3927 N push force at 0.5 MPa is ideal for maintaining precise tension on heavy-duty conveyor belts or operating robust product stops on packaging lines.
Heavy Press & Clamping Fixtures
Delivers up to 7068 N of clamping force at 0.9 MPa for holding large workpieces during welding, machining, or assembly operations where a fixed foot mount is required.
Material Handling & Lift Gates
Provides the muscle for lifting and lowering gates or diverters in material handling systems, with the LB mount offering a stable, bolted-down platform.
Is the Airtac SC100 Standard Cylinder SC100X225LB the Right Cylinder?
Select the SC100X225LB when your application requires a robust 100 mm bore with a 225 mm stroke and a fixed foot mount. If your force requirements are lower, stepping down to the 80 mm bore (2513 N at 0.5 MPa) can reduce size and cost; for higher forces, the 125 mm bore offers 6136 N at the same pressure. The LB foot mount (F-SC100LB) rigidly secures the cylinder body to a machine bed or frame.
For a 225 mm stroke, ensure the load is guided and side forces are minimal to prevent bending stress on the 25 mm rod. When replacing, match five key points: 100 mm bore, 225 mm stroke, PT1/2 port thread, the LB foot mounting accessory, and the non-magnetic piston (no -S suffix).
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 SC100X225LB FAQ
The theoretical push force is 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at the maximum operating pressure of 0.9 MPa. The pull force on the return stroke is 3681 N at 0.5 MPa due to the rod area.
No. The AirTAC SC series is a tie-rod cylinder and is shorter than an equivalent ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC100 tie-rod cylinder with the same stroke, PT port, and LB foot mount.
