About the Airtac SC100 Standard Cylinder SC100X290STC
The SC100X290STC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa and up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 290 mm stroke, this model features a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end to decelerate the load smoothly.
This configuration includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (suffix -TC) supplied with the TCM1 bracket (F-SC100TC), ideal for applications requiring the cylinder to pivot. It uses standard PT ports and TPU seals for operation in temperatures from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X290STC Is Used
Material Handling Gates
The 3927 N push force at 0.5 MPa easily actuates heavy diverter gates and chutes on conveyor lines, with the centre trunnion mount allowing the cylinder to swing as it strokes.
Clamping & Fixturing
Provides powerful, controlled clamping for large workpieces in welding or machining fixtures. The adjustable cushion protects the fixture from impact, and the magnet enables end-of-stroke detection.
Press & Forming Assist
Delivers up to 7068 N of force at 0.9 MPa for light pressing, bending, or forming operations. The tie-rod construction offers robust, serviceable performance in demanding cycles.
Is the Airtac SC100 Standard Cylinder SC100X290STC the Right Cylinder?
Select the SC100 bore when your application requires a push force between the 2513 N of an 80 mm bore and the 6136 N of a 125 mm bore at 0.5 MPa. For this 290 mm stroke, ensure the load is guided and free from significant side forces; the 25 mm rod is robust, but long unsupported strokes can still cause rod bearing wear under lateral loads. For exact drop-in replacement, match the 100 mm bore, 290 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S) sensor compatibility.

- ✓ 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 SC100X290STC FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, push force increases to 5497 N. The maximum theoretical force at 1.0 MPa is 801 kgf, but the recommended maximum operating pressure is 0.9 MPa, yielding a push force of 7068 N.
No. The SC100X290STC is a double-acting cylinder and will drift or drop if pressure is lost or the directional valve is centered. To hold a load safely without live pressure, you must add an external mechanical lock, a rod brake, or a pilot-operated check valve in the circuit.
