About the Airtac SC100 Standard Cylinder SC100X325STC
The SC100X325STC is a double-acting pneumatic cylinder delivering 3927 N of push force at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa. With a 100 mm bore and 325 mm stroke, this model features a robust 25 mm diameter piston rod and an adjustable air cushion length of 29 mm to decelerate end-of-stroke impacts effectively.
This configuration includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC100TC) to handle pivoting loads. The body length A is 188 mm, and the standard PT1/2 port thread ensures straightforward pneumatic connections.

Where the Airtac SC100 Standard Cylinder SC100X325STC Is Used
Conveyor Diverter Gates
The 3927 N push force at 0.5 MPa and pivoting trunnion mount make this cylinder ideal for actuating heavy diverter gates on high-throughput conveyor systems.
Welding Fixture Clamping
With a built-in magnet for sensor confirmation and 7068 N of clamping force at 0.9 MPa, it reliably secures large weldments in automated robotic welding cells.
Material Lift & Tilt Mechanisms
The centre trunnion mount allows the cylinder to pivot smoothly while providing the high thrust needed to tilt heavy bins or platforms in industrial lifting stations.
Is the Airtac SC100 Standard Cylinder SC100X325STC the Right Cylinder?
For applications requiring more force, stepping up to a 125 mm bore provides 6136 N at 0.5 MPa. If a shorter, more compact footprint is needed, the 80 mm bore generates 2513 N. This 325 mm stroke model requires careful management of side loads; an external guide or guided cylinder is strongly recommended to protect the 25 mm rod from bending stress.
To ensure a correct replacement, match five key points: the 100 mm bore, 325 mm stroke, PT1/2 port thread, the centre trunnion (TC) mounting accessory, and the built-in magnet (-S) for sensor compatibility. This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profiles.
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 SC100X325STC FAQ
At 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 reaches 7068 N. The theoretical maximum force at 1.0 MPa is 801 kgf.
No. As a standard double-acting cylinder, the SC100X325STC will drift or drop if pressure is lost or the directional valve is centered. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod brake.
