About the Airtac SC100 Standard Cylinder SC100X120TC
The SC100X120TC is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa (7068 N at 0.9 MPa). With a 100 mm bore and 120 mm stroke, it uses a 25 mm diameter piston rod with M20x1.5 threads and PT3/8 ports, making it a robust actuator for medium-to-heavy linear motion tasks.
This specific configuration includes a TC centre trunnion mount, supplied with the TCM1 bracket (F-SC100TC), which allows the cylinder to pivot and is ideal for swinging or articulating loads. Operating on filtered air from 0.15 to 1.0 MPa, the SC100X120TC features an adjustable air cushion to decelerate the piston smoothly at the end of its 120 mm travel.

Where the Airtac SC100 Standard Cylinder SC100X120TC Is Used
Conveyor Diverters
The pivoting action of the TC trunnion mount combined with 3927 N of force makes this cylinder perfect for actuating heavy-duty diverter gates on high-throughput conveyor systems.
Clamping Fixtures
Delivers a powerful, controlled clamping force for holding large workpieces in CNC machining centres or welding jigs, where the trunnion mount allows the cylinder body to self-align.
Agricultural Equipment
Suitable for actuating chutes or hopper doors on heavy farm machinery. The robust tie-rod design and 25 mm rod withstand harsh, dusty environments when properly maintained.
Is the Airtac SC100 Standard Cylinder SC100X120TC the Right Cylinder?
The SC100 bore provides 3927 N of push force at 0.5 MPa. If your application requires less force, stepping down to an SC80 bore reduces push force to 2513 N at the same pressure. For higher force demands, an SC125 bore offers 6136 N. Always ensure the load is guided externally when using a trunnion mount to prevent the piston rod from absorbing bending moments.
For a drop-in replacement, match these five attributes: 100 mm bore, 120 mm stroke, PT port thread, TC centre trunnion mounting, and the absence of a magnet. This ensures dimensional and functional interchangeability with another AirTAC SC series tie-rod cylinder.

- ✓ 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 SC100X120TC FAQ
At the standard operating pressure of 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, the push force increases to 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. The SC100X120TC is a standard double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke to reduce impact. For load holding, you must add an external rod brake or a pilot-operated check valve.
