About the Airtac SC80 Standard Cylinder SC80X125SH
The SC80X125SH is an 80 mm bore double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa (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 air cushion provide stable deceleration at end-of-stroke.
This model is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0–150 °C. The combination makes it a reliable choice for hot environments where sensor feedback is required.

Where the Airtac SC80 Standard Cylinder SC80X125SH Is Used
Foundry & Heat-Treat Clamping
Viton seals and a 0–150°C rating allow this cylinder to operate reliably near furnaces or in hot-work tooling, with the magnetic piston confirming clamp position via barrel-mounted sensors.
Hot-Material Diverting
The 125 mm stroke and 2513 N push force at 0.5 MPa effectively divert hot parts on conveyor lines, while the adjustable cushion protects the cylinder from impact wear.
High-Temperature Pressing
Delivers up to 4523 N at 0.9 MPa for pressing or forming operations in autoclaves and heated platen presses, with end-of-stroke sensing for cycle automation.
Is the Airtac SC80 Standard Cylinder SC80X125SH the Right Cylinder?
For higher force, the SC100 bore steps up to 3927 N at 0.5 MPa; for a lighter, faster actuator, the SC63 bore provides 1559 N. The 125 mm stroke is well within the 1500 mm maximum for this bore, keeping the rod well-supported. When replacing, match bore (80), stroke (125), PT port thread, the -S magnet option, and the -H Viton seal material to ensure sensor and thermal compatibility.
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 SC80X125SH FAQ
At 0.5 MPa, it generates 2513 N pushing and 2268 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix indicates a built-in magnet, allowing AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors to be clamped directly onto the tie-rod barrel for piston position detection.
