About the Airtac SC80 Standard Cylinder SC80X805STC
The AirTAC SC80X805STC is a double-acting single-rod pneumatic cylinder with an 80 mm bore and an 805 mm stroke, delivering a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa). Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for mid-to-heavy linear moves.
This model is factory-equipped with 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-SC80TC) for pivoting applications. The body length A is 182 mm, making the total extended length approximately 987 mm.

Where the Airtac SC80 Standard Cylinder SC80X805STC Is Used
Conveyor Diverters
The 805 mm stroke and 2513 N push force at 0.5 MPa reliably shift packages or pallets across wide conveyor junctions, with the centre trunnion allowing the cylinder to pivot as the diverter arm swings.
Welding Fixture Clamping
Delivers 4523 N of clamping force at 0.9 MPa for holding large fabrications. The built-in magnet lets CMSG sensors confirm full clamp extension before the weld cycle starts.
Large Gate Actuation
Operates a sliding or pivoting hopper gate with an 805 mm travel. The trunnion mount absorbs the arc of motion, and the adjustable cushion softens the stop under the gate's inertia.
Is the Airtac SC80 Standard Cylinder SC80X805STC the Right Cylinder?
Choose the SC80 bore when your application needs between 2513 N and 4523 N of push force; for lighter loads around 1559 N, step down to the SC63, and for heavier demands up to 3927 N at 0.5 MPa, move up to the SC100. At an 805 mm stroke, the 25 mm rod is long and unsupported—any side load will cause bending stress on the rod bearing, so use an external linear guide or a guided cylinder to protect the rod and seals.
For a direct replacement, match five points: 80 mm bore, 805 mm stroke, PT port thread, centre trunnion (TC) mounting with the TCM1 bracket, and the built-in magnet for sensor compatibility. This tie-rod SC cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
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 SC80X805STC 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 SC80X805STC is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centred. To hold a position or load without live pressure, you must add a pilot-operated check valve, rod lock, or external brake—the air cushion only decelerates the piston, it does not lock it.
