About the Airtac SC80 Standard Cylinder SC80X125SN
The SC80X125SN is a double-acting 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 and 125 mm stroke suit medium-duty clamping, pressing, and material-handling tasks where a compact tie-rod body is preferred.
This model includes a built-in magnet (-S suffix), allowing CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the barrel for non-contact position sensing. NBR seals (-N) provide reliable sealing for standard industrial air, while the PT1/4 port thread and 25 mm piston rod with M20x1.5 male thread ensure straightforward pneumatic connections and tooling attachment.

Where the Airtac SC80 Standard Cylinder SC80X125SN Is Used
Conveyor Diverter Gates
Actuates diverter arms on packaging and sortation conveyors. The built-in magnet enables end-of-stroke confirmation via barrel-mounted sensors, while 2513 N of push force handles medium-weight parcel redirection.
Pneumatic Clamping Fixtures
Provides consistent 4523 N clamping force at 0.9 MPa for CNC jigs and welding fixtures. NBR seals offer good wear resistance in oily shop air, and the magnet confirms clamp engagement before machining starts.
Automated Assembly Presses
Delivers a controlled 125 mm stroke for press-fit insertion of bearings, bushings, or seals. Sensor feedback from the integrated magnet signals cycle completion to the PLC, improving assembly line throughput.
Is the Airtac SC80 Standard Cylinder SC80X125SN the Right Cylinder?
Choose the SC80 bore when your application needs roughly 2500 N of force at standard shop air; stepping down to the SC63 bore drops push force to 1559 N at 0.5 MPa, while moving up to the SC100 bore raises it to 3927 N. The 125 mm stroke is well within the 1500 mm maximum standard stroke for this bore, so no special stroke approval is needed.
For replacement, match five points: 80 mm bore, 125 mm stroke, PT port thread, the built-in magnet (-S), and the basic (no bracket) mounting. If side loads are present even at this medium stroke, consider an external guide rod assembly to protect the rod bearing from bending stress.
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 SC80X125SN 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. These values assume clean, filtered air at 40 µm and standard temperature conditions.
Yes, provided the original cylinder matches the 80 mm bore, 125 mm stroke, PT port thread, built-in magnet, and basic (no bracket) mounting. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders. Always verify the body length (182 mm + stroke) and rod thread (M20x1.5) before ordering.
