About the Airtac SC100 Standard Cylinder SC100X435STC
The SC100X435STC is a double-acting pneumatic cylinder delivering substantial push force of 3927 N at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. Its 100 mm bore and 435 mm stroke make it a robust actuator for medium-to-heavy industrial linear motion, featuring a 25 mm diameter piston rod and a 29 mm adjustable air cushion at each end to decelerate the load smoothly.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (-TC suffix) supplied with the TCM1 bracket (F-SC100TC) for pivoting applications. The standard PT ports and TPU seals provide reliable operation within a -20 to +70 °C temperature range, making this genuine AirTAC cylinder a versatile choice for demanding automation tasks.

Where the Airtac SC100 Standard Cylinder SC100X435STC Is Used
Conveyor Diverter Gates
The 435 mm stroke and high force output reliably actuate heavy diverter gates on wide conveyor lines, directing packages or bulk materials with the trunnion mount allowing the cylinder to pivot freely.
Automated Welding Fixtures
Clamps large weldments securely with 7068 N of force at 0.9 MPa. The built-in magnet provides end-of-stroke confirmation via sensors, ensuring the fixture is fully engaged before the robot cycle starts.
Press Feed Mechanisms
Pushes heavy steel sheets or blanks into a stamping press. The centre trunnion mount absorbs the pivoting motion, while the adjustable cushioning prevents impact damage at the end of the 435 mm feed stroke.
Is the Airtac SC100 Standard Cylinder SC100X435STC the Right Cylinder?
Select the SC100X435STC when your application requires a force class around 4000 N at standard plant pressure. If your load is significantly lighter, consider stepping down to an 80 mm bore (2513 N push at 0.5 MPa) for reduced air consumption and a smaller footprint. For heavier loads, the 125 mm bore provides 6136 N at the same pressure.
With a stroke of 435 mm, ensure side loads are minimal or managed with an external guide system, as the unsupported 25 mm rod is susceptible to bending under lateral forces. For direct replacement, match the 100 mm bore, 435 mm stroke, PT port thread, centre trunnion (TC) mounting, and the integrated magnet (-S) sensor capability.

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 SC100X435STC FAQ
At 0.5 MPa, 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. The theoretical maximum force at 1.0 MPa is 801 kgf.
The -TC suffix means this cylinder is equipped with a centre trunnion mount (part code F-SC100TC) and the TCM1 bracket. This allows the entire cylinder body to pivot around its centre point, which is essential for applications where the load moves in an arc. It prevents side-loading on the piston rod bearing.
