About the Airtac SC80 Standard Cylinder SC80X754STC
The AirTAC SC80X754STC is a double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a strong mid-range actuator for long linear moves. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration at the ends of the 754 mm stroke.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and the TC centre trunnion mount (supplied with TCM1 bracket, part code F-SC80TC) allows the cylinder to pivot during operation. The body length A is 182 mm, giving an extended length of approximately 936 mm.

Where the Airtac SC80 Standard Cylinder SC80X754STC Is Used
Long-Reach Part Transfer
The 754 mm stroke and 2513 N push force move heavy components between distant conveyor stations, with the trunnion mount absorbing alignment shifts.
Pivoting Clamp Fixtures
Centre trunnion mounting lets the cylinder swing as it clamps large weldments or assemblies, while the magnet enables end-of-stroke confirmation via reed sensors.
Pallet Dispenser Pusher
Delivers consistent 0.5-0.7 MPa thrust to push tall stacks of empty pallets into a dispenser magazine, with the adjustable cushion softening the return stroke.
Is the Airtac SC80 Standard Cylinder SC80X754STC the Right Cylinder?
Choose the SC80 when the SC63’s 1559 N at 0.5 MPa is borderline; stepping up to this 80 mm bore nearly doubles the available force. For strokes above 300 mm like this 754 mm unit, side-load management is critical—an unsupported 25 mm rod at full extension can bend under lateral force, so use an external guide rail or a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match five points: 80 mm bore, 754 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the -S magnet for sensor compatibility. This SC is a tie-rod design, not an ISO 15552 profile, so verify body length A (182 mm) against your mounting space.
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 SC80X754STC FAQ
At 0.5 MPa, push force is 2513 N and pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, push reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80 is a double-acting cylinder and does not lock or hold position when pressure is exhausted or the valve is centered—the piston will drift. For load holding, add a pilot-operated check valve or an external rod brake.
