About the Airtac SC80 Standard Cylinder SC80X395STC
The AirTAC SC80X395STC is an 80 mm bore double-acting tie-rod cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa. With a 395 mm stroke and a 25 mm diameter piston rod, it is well-suited for medium-duty linear tasks where a pivoting mount is required.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a centre trunnion mount (TC) supplied with the TCM1 bracket for applications needing the cylinder to swing. The adjustable pneumatic cushion (28 mm length) decelerates the piston smoothly, and the PT1/4 port threads ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X395STC Is Used
Conveyor Diverter Gates
The 395 mm stroke and pivoting trunnion mount allow this cylinder to swing heavy diverter arms on packaging lines, directing products between lanes with sensor-confirmed position.
Clamping & Welding Fixtures
Delivers 2513 N of clamping force at standard line pressure. The built-in magnet enables end-of-stroke detection to interlock with robotic welding or machining cycles.
Agricultural Implement Control
Used to actuate chutes or hopper doors on farm machinery. The centre trunnion mount handles the arcing motion, while the TPU seals perform reliably in typical outdoor temperatures.
Is the Airtac SC80 Standard Cylinder SC80X395STC the Right Cylinder?
For applications needing a pivoting actuator with position feedback, the SC80X395STC is an ideal choice. If your load requires more force, consider stepping up to the 100 mm bore (3927 N push at 0.5 MPa); for a lighter, more compact solution, the 63 mm bore (1559 N at 0.5 MPa) may suffice.
At 395 mm of stroke, the unsupported rod is extended significantly. Ensure side loads are minimized or use an external guide system to prevent rod bending and premature bearing wear. When replacing, match all five key points: 80 mm bore, 395 mm stroke, PT port thread, the -S magnet option for sensors, and the TC centre trunnion mounting with its F-SC80TC bracket.
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 SC80 Standard Cylinder SC80X395STC FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with the same bore, stroke, PT ports, magnet option, and TC centre trunnion mount.
