About the Airtac SC80 Standard Cylinder SC80X125S
The SC80X125S is an 80 mm bore double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa. Its 125 mm stroke suits medium-travel clamping and pressing tasks, while the 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth end-of-stroke deceleration.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for reliable position feedback. The body length A is 182 mm, giving a total extended length of approximately 307 mm, and the PT3/8 ports keep connections compact.

Where the Airtac SC80 Standard Cylinder SC80X125S Is Used
Conveyor Stop & Divert
The 2513 N push force at 0.5 MPa easily stops or diverts medium-weight packages on a conveyor line. The built-in magnet lets you add sensors to confirm the gate is fully retracted or extended.
Assembly Press
Delivers up to 4523 N at 0.9 MPa for pressing bushings, bearings, or pins into housings. The 28 mm adjustable cushion absorbs impact energy, protecting the tooling and cylinder at high cycle rates.
Automated Clamping
Use the SC80X125S to clamp workpieces in CNC fixtures or welding jigs. The -S magnet provides end-of-stroke confirmation to the PLC, ensuring the part is securely held before the cycle starts.
Is the Airtac SC80 Standard Cylinder SC80X125S the Right Cylinder?
Choose the SC80 when the SC63's 1559 N push at 0.5 MPa is marginal for your load. If you need higher force, the SC100 offers 3927 N at the same pressure. For this 125 mm stroke, the rod is well supported, but always align the load axially to avoid side-load bending on the rod bearing.
To match this cylinder as a replacement, confirm five points: 80 mm bore, 125 mm stroke, PT3/8 port thread, the built-in magnet for sensor mounting, and the basic (no bracket) mounting style. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile 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 SC80X125S FAQ
At 0.5 MPa (72.5 psi) the cylinder pushes with 2513 N. At 0.7 MPa it produces 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical force at 1.0 MPa is 513 kgf, but the maximum operating pressure is 1.0 MPa.
Yes. The -S suffix in the model code means a magnet is built into the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional brackets.
