About the Airtac SC100 Standard Cylinder SC100X42
The SC100X42 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a compact 42 mm stroke. At 0.5 MPa it produces 3927 N of push force, placing it in a high-force class suitable for pressing, clamping, and heavy-duty actuation where space is limited.
This model features a 25 mm diameter piston rod, PT1/2 ports, and a 29 mm adjustable air cushion at each end to decelerate the load smoothly. The body length A is 188 mm, giving a total extended length of approximately 230 mm. Standard TPU seals provide an operating temperature range of -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X42 Is Used
Short-Stroke Clamping
The 42 mm stroke and 3927 N force at 0.5 MPa make this cylinder ideal for pneumatic clamping fixtures in machining or welding cells where jaw travel is minimal but holding force must be high.
Press-Fit Assembly
Delivers up to 7068 N at 0.9 MPa for pressing bearings, bushings, or pins into housings on automated assembly lines. The adjustable cushion protects the part and tooling at end of stroke.
Diverter Gate Actuation
Powers diverter gates on heavy-duty conveyor systems. The compact 42 mm stroke cycles quickly to redirect packages or pallets, while the 25 mm rod withstands repetitive impact loads.
Is the Airtac SC100 Standard Cylinder SC100X42 the Right Cylinder?
Choose the SC100 bore when your application demands roughly 3900 N at standard plant pressure; if you need less force, stepping down to an SC80 bore provides 2513 N at the same 0.5 MPa. For strokes of 300 mm or more, evaluate side-load conditions and consider an external guide or a guided cylinder to protect the rod bearing from bending moments.
To replace an existing cylinder, match five points: 100 mm bore, 42 mm stroke, PT1/2 port thread, basic mounting (no accessory bracket), and no magnet. This ensures identical form, fit, and function within the AirTAC SC tie-rod family.
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 SC100X42 FAQ
At 0.5 MPa the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa push force reaches 5497 N, and at the maximum operating pressure of 0.9 MPa it delivers 7068 N. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC series is a tie-rod cylinder that is shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. Replace it only with another AirTAC SC tie-rod cylinder of the same bore, stroke, port thread, and mounting configuration.
