About the Airtac SC100 Standard Cylinder SC100X950
The SC100X950 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 100 mm bore with a 950 mm stroke. At 0.5 MPa operating pressure, it generates 3927 N of push force and 3681 N on the pull stroke, driven by a 25 mm diameter piston rod. The cylinder body length (A) measures 188 mm, resulting in a total extended length of approximately 1138 mm.
This model uses the standard PT1/2 port thread and M20x1.5 rod thread, with an adjustable air cushion length of 29 mm at each end to decelerate the piston smoothly. It is built with TPU/NBR seals for a standard operating temperature range of -20 to +70 °C and does not include a magnetic piston, making it a straightforward, high-force actuator for long linear movements.

Where the Airtac SC100 Standard Cylinder SC100X950 Is Used
Pallet Transfer Systems
Provides the high push force needed to move heavy pallets or bins across roller conveyors in distribution centers, with the long 950 mm stroke covering full transfer distances.
Heavy-Duty Clamping Fixtures
Delivers nearly 4000 N of force at standard line pressure to securely clamp large weldments or castings during machining or assembly, accommodating deep workpieces with its long stroke.
Baler and Compactor Ejection
Used to push compacted material bales out of industrial balers or compactors, where the combination of high force and a long, 950 mm ejection stroke is required to clear the chamber.
Is the Airtac SC100 Standard Cylinder SC100X950 the Right Cylinder?
With 3927 N of push force at 0.5 MPa, the SC100X950 sits between the SC80 (2513 N) and the SC125 (6136 N). If your application requires higher force, stepping up to the 125 mm bore provides a substantial increase; for lower force and a lighter, more compact unit, the 80 mm bore is a suitable alternative. This cylinder is a basic configuration with no mounting accessories, magnet, or special seals, so you must order any required brackets separately.
This 950 mm stroke is well within the 1500 mm maximum standard stroke for the 100 mm bore. However, at this extended length, the 25 mm rod is susceptible to bending under side loads. For any application involving non-axial forces, you must use an external guide system or a guided cylinder to protect the rod bearings and ensure reliable operation. For a direct replacement, match the 100 mm bore, 950 mm stroke, PT1/2 ports, and the basic (no-mount) configuration.
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 SC100X950 FAQ
At 0.7 MPa operating pressure, the SC100X950 generates a theoretical push force of 5497 N and a pull force of 3681 N. The maximum force at 0.9 MPa is 7068 N push. These values assume a static load; always apply a safety factor for dynamic applications.
No. The SC100X950 is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The piston will drift or the load will drop. To hold a load safely without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
