About the Airtac SC100 Standard Cylinder SC100X400TC
The SC100X400TC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa), ideal for medium-to-heavy linear actuation tasks. Its 400 mm stroke is paired with a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end, providing controlled deceleration for moving substantial loads.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC100TC), allowing the cylinder to pivot as it strokes—essential for applications where the load follows an arc. The PT1/2 port thread and standard TPU seals suit filtered-air systems operating from -20 to +70 °C.

Where the Airtac SC100 Standard Cylinder SC100X400TC Is Used
Conveyor Diverters
Pivots a heavy diverter gate on a packaging line, using the TC trunnion mount to swing the cylinder body through the arc of motion.
Clamping & Fixturing
Applies up to 7068 N of clamping force at 0.9 MPa to hold large weldments or castings during machining or assembly.
Press & Forming Assist
Provides the primary linear thrust for a small pneumatic press or forming station, with adjustable cushioning to reduce shock at the end of the 400 mm stroke.
Is the Airtac SC100 Standard Cylinder SC100X400TC the Right Cylinder?
Choose the SC100 bore when the SC80's 2513 N at 0.5 MPa is marginal; step up to the SC125 (6136 N at 0.5 MPa) if your load exceeds 3900 N. For this 400 mm stroke, ensure the rod is not subjected to lateral forces—use an external linear guide or a guided cylinder if side loading is present, as a long unsupported 25 mm rod can bend under off-axis loads. To replace an existing cylinder, match the 100 mm bore, 400 mm stroke, PT1/2 ports, centre trunnion (TC) mount with TCM1 bracket, and confirm no magnet sensor is required.

- ✓ 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 SC100X400TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 7068 N.
No. The SC100 is a double-acting cylinder and will not hold a load if pressure is lost or the valve is centered. The adjustable air cushion only decelerates the piston at the end of its stroke; it is not a locking or holding device. For load holding, you must add a pilot-operated check valve or an external rod brake.
