About the Airtac SC100 Standard Cylinder SC100X75TC
The SC100X75TC is a double-acting pneumatic cylinder with a 100 mm bore and 75 mm stroke, equipped with a centre trunnion (TC) mount for pivoting applications. At 0.5 MPa air pressure, it generates a push force of 3927 N, making it a strong actuator for medium-duty industrial tasks.
This model uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT3/8 ports. The total extended body length is approximately 263 mm (188 mm body length A + 75 mm stroke). The adjustable air cushion at each end is 29 mm long, helping to decelerate the piston smoothly. The TC mount ships with the TCM1 trunnion bracket (accessory code F-SC100TC).

Where the Airtac SC100 Standard Cylinder SC100X75TC Is Used
Conveyor Diverter Gates
The 75 mm stroke and centre trunnion mount allow the cylinder to pivot, making it ideal for actuating diverter gates on packaging or sorting conveyors where a swinging motion is required.
Clamping & Staking Fixtures
With 3927 N of force at 0.5 MPa, this cylinder provides ample clamping power for welding fixtures, assembly jigs, or staking operations in metal fabrication cells.
Process Valve Actuation
The robust tie-rod construction and PT3/8 ports suit it for automating quarter-turn ball or butterfly valves on water, chemical, or air lines, where a pivoting mount simplifies linkage.
Is the Airtac SC100 Standard Cylinder SC100X75TC the Right Cylinder?
Choose the SC100 bore when your application needs around 3927 N of push force at 0.5 MPa. If you require less force, the SC80 bore provides 2513 N in a lighter package. For higher force, the SC125 delivers 6136 N at the same pressure.
For a direct replacement, match five key points: 100 mm bore, 75 mm stroke, PT3/8 port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the standard magnet-free configuration. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC100 tie-rod cylinders.
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 SC100X75TC 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.
No. The SC100X75TC is a double-acting cylinder and will not hold its position if air pressure is lost or the directional valve is centred. The adjustable air cushion only decelerates the piston at the end of stroke; it is not a locking or holding device. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
