About the Airtac SC100 Standard Cylinder SC100X40
The SC100X40 is a compact-stroke pneumatic workhorse delivering 3927 N of push force at 0.5 MPa (up to 7068 N at the 0.9 MPa maximum operating pressure). Its 100 mm bore and 40 mm stroke suit applications needing high clamping or pressing force over a short travel distance.
This double-acting tie-rod cylinder uses a 25 mm diameter piston rod with M20x1.5 male threads and PT1/2 ports. The body length A is 188 mm, giving a total extended length of approximately 228 mm. Standard TPU seals provide a -20 to +70 C operating range, and the adjustable air cushion at each end decelerates the piston smoothly.

Where the Airtac SC100 Standard Cylinder SC100X40 Is Used
Short-Stroke Clamping
Delivers up to 7068 N at 0.9 MPa for pressing bearings, holding workpieces during machining, or powering assembly fixtures where travel is minimal.
Die Ejection & Forming
The 40 mm stroke provides a sharp, powerful punch for ejecting parts from injection molds or operating cut-off tools in packaging lines.
Heavy Part Stops
Ideal as a pneumatic stop gate on heavy-duty conveyors, raising and lowering a blade with 3927 N of force to halt pallets or large totes.
Is the Airtac SC100 Standard Cylinder SC100X40 the Right Cylinder?
Choose the SC100X40 when you need high force in a short linear stroke. If the 3927 N push at 0.5 MPa is insufficient, stepping up to the SC125 bore provides 6136 N at the same pressure. For lower force needs, the SC80 delivers 2513 N at 0.5 MPa.
To ensure a direct replacement, match five points: 100 mm bore, 40 mm stroke, PT1/2 port thread, basic mounting (no bracket), and the standard non-magnet piston. This SC cylinder is a tie-rod design 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 SC100X40 FAQ
At 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, push force reaches 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than ISO 15552 profile cylinders. It is not dimensionally interchangeable. It directly replaces another AirTAC SC100 cylinder with the same bore, stroke, PT ports, and basic mounting.
