About the Airtac SC100 Standard Cylinder SC100X205STC
The AirTAC SC100X205STC is a double-acting pneumatic cylinder delivering a substantial 3927 N of push force at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and a 205 mm stroke, this model is built on a robust tie-rod construction that is shorter than an ISO 15552 profile, making it ideal for installations where space is limited.
This specific configuration includes a built-in magnet for sensor compatibility and a centre trunnion mount, supplied with the TCM1 bracket, for smooth pivoting motion. The 25 mm diameter rod and PT1/2 port ensure efficient air flow, while the 29 mm adjustable air cushion at each end decelerates the piston to protect the end caps during high-speed operation.

Where the Airtac SC100 Standard Cylinder SC100X205STC Is Used
Conveyor Diverters
The 3927 N push force at 0.5 MPa reliably actuates heavy-duty diverter gates on wide conveyor systems, handling large packages or pallets with the trunnion mount absorbing the pivot action.
Clamping & Fixturing
Ideal for heavy part clamping in machining centres, the 100 mm bore provides the high force needed to secure large fabrications, with the magnet enabling end-of-stroke confirmation via sensors.
Material Handling Tippers
The centre trunnion mount allows the cylinder to pivot smoothly as it tips heavy bins or hoppers, with the 205 mm stroke providing the necessary angular travel for complete discharge.
Is the Airtac SC100 Standard Cylinder SC100X205STC the Right Cylinder?
Select the SC100 series when your application requires a force class around 4000 N at standard plant pressure. If your load is lighter, stepping down to an 80 mm bore reduces the push force to 2513 N at 0.5 MPa. For a stroke of 205 mm, ensure the rod is protected from side loads; an external guide or a guided cylinder is recommended to prevent bending of the 25 mm rod. For a direct replacement, match the 100 mm bore, 205 mm stroke, PT1/2 port thread, centre trunnion (TC) mount, and the integrated magnet (-S) for sensor mounting.

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 SC100X205STC FAQ
At 0.5 MPa (approx. 73 psi), the theoretical 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. These values are based on a 100 mm bore and a 25 mm rod diameter.
No. The SC100X205STC is a double-acting cylinder and will not hold its position if air pressure is lost or the valve is centred. The adjustable air cushion only decelerates the piston at the stroke end; it is not a locking or holding brake. For load holding, you must add an external rod lock or a pilot-operated check valve.
