About the Airtac SC80 Standard Cylinder SC80X128
The SC80X128 is an 80 mm bore double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With a 128 mm stroke, this model provides a compact linear motion solution where the total extended body length is approximately 310 mm, making it suitable for medium-stroke clamping and pressing fixtures.
This cylinder features a 25 mm diameter piston rod with M20x1.5 male threads and PT3/8 port connections. The adjustable pneumatic cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-of-stroke impact. The standard TPU seals provide reliable operation in ambient temperatures from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X128 Is Used
Product Diverting Gates
The 128 mm stroke and 2513 N push force at 0.5 MPa reliably actuates diverter gates on packaging conveyors, providing the necessary thrust to redirect medium-weight parcels without slowing the line.
Assembly Presses
Delivers a controlled 4523 N maximum force for pressing bushings or bearings into housings. The adjustable cushion protects the tooling and part by decelerating the 25 mm rod smoothly at the end of the press stroke.
Pallet Stop Mechanisms
With its robust tie-rod construction, the SC80X128 stops and releases pallets on gravity or powered roller conveyors. The 28 mm cushion absorbs the kinetic energy of the moving load for quiet, low-wear operation.
Is the Airtac SC80 Standard Cylinder SC80X128 the Right Cylinder?
Select the SC80X128 for applications needing around 2500 N of force; if your load requires significantly less, stepping down to a 63 mm bore (1559 N at 0.5 MPa) can reduce air consumption. For higher force requirements, the 100 mm bore provides 3927 N at the same pressure. The 128 mm stroke is well within the 1500 mm maximum standard stroke for this bore, ensuring standard lead times.
When replacing an existing cylinder, match five key points: 80 mm bore, 128 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC80 or an equivalent tie-rod design.
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 SC80X128 FAQ
At the standard operating pressure of 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, the push force reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
Not on this specific model code SC80X128. The code lacks the '-S' suffix, meaning the piston does not have a built-in magnet. To use CMSG or DMSG sensors for position feedback, order the SC80X128-S variant, which includes the magnet.
