About the Airtac SC80 Standard Cylinder SC80X700STC
The AirTAC SC80X700STC is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 80 mm bore, 25 mm diameter piston rod, and 700 mm stroke suit medium-to-long linear movements in automation, pressing, and material handling where a compact tie-rod design is preferred.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, plus a centre trunnion (TC) mount with the TCM1 bracket (F-SC80TC) for pivoting applications. The adjustable air cushion (28 mm) decelerates the piston smoothly at stroke ends, and the PT1/8 ports keep plumbing simple. Total body length A is 182 mm, giving an extended length of approximately 882 mm.

Where the Airtac SC80 Standard Cylinder SC80X700STC Is Used
Conveyor Diverters & Gates
The 700 mm stroke and centre trunnion mount allow the cylinder to pivot as it extends, making it ideal for actuating diverter arms or gates on packaging and sortation conveyors.
Clamping & Assembly Jigs
With 2513 N of force at 0.5 MPa and sensor-ready magnet, this cylinder provides consistent clamping pressure for welding fixtures or assembly stations, with end-of-stroke confirmation via CMSG sensors.
Palletising Pushers
Delivers the long reach needed to push cartons or trays across a palletising table. The adjustable cushion protects the cylinder and product by softening the end-of-stroke impact.
Is the Airtac SC80 Standard Cylinder SC80X700STC the Right Cylinder?
Choose the SC80 bore when your application needs roughly 2500 N at standard plant air; if you require closer to 1500 N, step down to the SC63 (1559 N push at 0.5 MPa), and for about 3900 N move up to the SC100. For this 700 mm stroke, the rod is long relative to its 25 mm diameter—ensure the load is guided externally or use a guided cylinder if side forces are present, because an unsupported rod will bend under off-axis loading.
When replacing an existing cylinder, match five points: 80 mm bore, 700 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the built-in magnet for sensor compatibility. The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC of the same configuration.
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 SC80X700STC FAQ
At 0.5 MPa the push force is 2513 N and pull force is 2268 N. At 0.7 MPa push reaches 3518 N, and at the maximum operating pressure of 0.9 MPa it delivers 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80 is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
