About the Airtac SC80 Standard Cylinder SC80X100STC
The SC80X100STC is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at 0.9 MPa) from an 80 mm bore. With a 100 mm stroke and a 25 mm diameter piston rod, it suits compact linear push/pull tasks where moderate travel and high force are needed.
This model includes a built-in magnet (-S) for mounting CMSG/DMSG/EMSG sensors directly on the tie-rod barrel, plus a centre trunnion mount (TC) supplied with the TCM1 bracket (F-SC80TC). The adjustable air cushion (28 mm) decelerates the piston smoothly at stroke end, protecting the end caps during high-cycle operation.

Where the Airtac SC80 Standard Cylinder SC80X100STC Is Used
Conveyor Diverters
The 2513 N push force at 0.5 MPa reliably actuates heavy-duty diverter gates and sortation arms on packaging and logistics conveyors.
Clamping & Fixturing
Delivers stable, high-force clamping for CNC machining fixtures and welding jigs, with sensor confirmation via the built-in magnet.
Pivoting Press Mechanisms
The centre trunnion mount allows the cylinder to pivot freely, making it ideal for toggle presses and articulating linkage systems.
Is the Airtac SC80 Standard Cylinder SC80X100STC the Right Cylinder?
Choose the SC80 when your load requires roughly 2500 N at standard plant pressure; if your force need is closer to 1500 N, the SC63 (1559 N at 0.5 MPa) may reduce air consumption. For strokes of 300 mm or more, verify rod-bearing bending limits and consider an external guide or guided cylinder to handle side loads.
When replacing an existing cylinder, match five points: 80 mm bore, 100 mm stroke, PT port thread, centre trunnion (TC) mounting, and the built-in magnet (-S). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile 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 SC80 Standard Cylinder SC80X100STC 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80 is a double-acting cylinder and does not hold position when pressure is exhausted or the valve is centred. If load holding is required, add a pilot-operated check valve or an external rod brake.
