About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125SH
The AirTAC SC125X125SH is a double-acting tie-rod cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at the maximum operating pressure of 0.9 MPa. Its 125 mm bore and 125 mm stroke make it a compact yet powerful actuator for medium-stroke pressing and clamping tasks.
This model includes a built-in magnet (suffix -S) for direct mounting of CMSG/DMSG/EMSG sensors, and high-temperature Viton seals (suffix -H) that extend the operating range to 0–150 °C. The 32 mm piston rod with M27x2 thread and 28 mm adjustable air cushion ensure smooth deceleration, while the PT1/2 port supplies the large air volume this ISO 6430 class cylinder demands.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125SH Is Used
High-Temperature Clamping
Viton seals allow continuous operation up to 150 °C, making the SC125X125SH ideal for clamping fixtures inside ovens, autoclaves, or near heat sources where standard seals would degrade.
Heavy Press & Forming
With 11045 N of force at 0.9 MPa, this cylinder suits small to medium pneumatic presses for forming, riveting, or stamping operations that require a short, powerful stroke.
Hot-Material Diverter Gates
The built-in magnet enables end-of-stroke sensing to confirm gate position, while the Viton seals survive the radiant heat from conveyors carrying hot castings or glass.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X125SH the Right Cylinder?
Choose the SC125 when your load requires roughly 6000 N at standard plant pressure; the next step down, the SC100, provides 3927 N at 0.5 MPa, while stepping up to the SC160 nearly doubles the force to 10053 N. For this 125 mm stroke, side-load risk is minimal, but always centre the load on the rod axis.
To replace an existing SC125X125SH, match five points: 125 mm bore, 125 mm stroke, PT1/2 port thread, the built-in magnet for sensor mounting, and the Viton seal material for high-temperature compatibility. The SC is a tie-rod cylinder 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 AIRTAC SC125-160 Standard Cylinder SC125X125SH FAQ
At 0.5 MPa, push force is 6136 N and pull force is 5734 N. At the maximum operating pressure of 0.9 MPa, push force reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC125X125SH is a double-acting cylinder and will drift or drop if pressure is lost or the valve is centred. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve. The adjustable air cushion only decelerates the piston at stroke end—it does not lock the position.
