About the Airtac SC80 Standard Cylinder SC80X140STC
The SC80X140STC is an 80 mm bore, 140 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It generates a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a robust mid-range actuator for industrial tasks. This model includes a built-in magnet (suffix -S) for mounting CMSG/DMSG/EMSG sensors directly on the barrel, plus a centre trunnion mount (suffix -TC) with the TCM1 bracket for pivoting applications.
With a 25 mm diameter piston rod and PT3/8 ports, the cylinder provides an adjustable air cushion of 28 mm to decelerate end-of-stroke travel smoothly. The body length A is 182 mm, giving a total extended length of approximately 322 mm. Standard TPU seals handle an operating temperature range of -20 to +70 °C, and the operating pressure spans 0.15 to 1.0 MPa with filtered air.

Where the Airtac SC80 Standard Cylinder SC80X140STC Is Used
Conveyor Diverter Gates
The 140 mm stroke and 2513 N push force reliably actuate diverter gates on packaging and sortation conveyors. The centre trunnion mount allows the cylinder body to pivot as the gate swings.
Clamping & Fixturing
Delivers up to 4523 N of clamping force at 0.9 MPa for CNC workholding and assembly fixtures. The built-in magnet enables end-of-stroke confirmation via CMSG/DMSG sensors.
Agricultural Machinery
Operates chute controls and hopper doors on farming equipment. The TPU seals and tie-rod construction withstand dusty conditions, while the trunnion mount handles the pivoting linkage.
Is the Airtac SC80 Standard Cylinder SC80X140STC the Right Cylinder?
Choose the SC80 bore when your application requires between 2513 N and 4523 N of push force. If the load is lighter, stepping down to the 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier demands, the 100 mm bore delivers 3927 N at 0.5 MPa.
To replace an existing cylinder, match five key points: 80 mm bore, 140 mm stroke, PT3/8 port thread, centre trunnion (TC) mounting with the F-SC80TC/TCM1 bracket, and the built-in magnet (-S) for sensor compatibility. The SC is a tie-rod design, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC tie-rod 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 SC80X140STC FAQ
At the standard 0.5 MPa operating pressure, the cylinder produces 2513 N extending (push) and 2268 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The SC80X140STC is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centred, the piston rod will drift or drop under load. For load-holding applications, you must add an external rod brake, a pilot-operated check valve, or a mechanical lock.
