About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150H
The SC125X150H is a double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa (11045 N at 0.9 MPa), built for heavy industrial actuation with a 125 mm bore and 150 mm stroke. This model features a 32 mm piston rod with M27x2 threads and PT1/2 ports, and includes Viton (FKM) seals that extend the operating temperature range to 0–150 °C, making it suitable for high-heat environments.
As a tie-rod cylinder with a body length A of 203 mm, the SC125X150H is shorter than an ISO 15552 profile cylinder and is an ISO 6430 class design. The adjustable air cushion at each end decelerates the piston over 28 mm to reduce end-of-stroke impact, protecting connected machinery during high-speed cycles.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150H Is Used
High-Temperature Process Automation
With Viton seals rated for 0–150 °C, this cylinder reliably actuates valves, dampers, and gates in furnaces, ovens, and autoclaves where standard seals would degrade.
Heavy-Duty Clamping & Pressing
Generating up to 11045 N of force, the SC125X150H provides the high clamping pressure needed for welding fixtures, die-casting moulds, and heavy assembly presses.
Material Handling & Sorting
The robust tie-rod construction and 32 mm rod handle the shock loads of diverting heavy packages, logs, or scrap metal on high-capacity conveyor systems.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X150H the Right Cylinder?
Choose the SC125 bore when your application demands between 6136 N and 11045 N of push force; if you need less, the SC100 bore provides 3927 N at 0.5 MPa. For strokes beyond 150 mm, the SC125 supports up to 1500 mm as standard, but always evaluate side-load conditions—longer strokes with this 32 mm rod may require an external guide or a guided cylinder to prevent rod bending under lateral forces.
To ensure a direct replacement, match five points: 125 mm bore, 150 mm stroke, PT port thread, the specific mounting accessory (this model is basic, with no bracket), and the magnet option (this model has no built-in magnet). The Viton seal variant is critical for applications operating above 70 °C.
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 AIRTAC SC125-160 Standard Cylinder SC125X150H FAQ
At the standard operating pressure of 0.7 MPa, the push force is 8590 N and the pull force is 5734 N. The maximum push force at 0.9 MPa is 11045 N. These forces are based on the 125 mm bore and 32 mm rod diameter.
No. The SC125X150H is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston will drift. For load-holding applications, you must add a pilot-operated check valve or an external mechanical rod lock.
