About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100H
The SC125X100H is a double-acting pneumatic cylinder with a 125 mm bore and 100 mm stroke, built with high-temperature Viton (FKM) seals for reliable operation from 0 to +150 °C. It generates a push force of 6136 N at 0.5 MPa and can reach 11045 N at the maximum operating pressure of 0.9 MPa, making it a strong choice for heavy-duty industrial tasks.
This ISO 6430 class tie-rod cylinder uses a 32 mm piston rod with an M27x2 thread and PT1/2 ports. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, protecting the end caps during high-speed cycles. The body length A is 203 mm, giving a compact footprint for its force class.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100H Is Used
High-Temperature Clamping
The Viton seals withstand 150°C, making this cylinder ideal for clamping fixtures in autoclaves, drying ovens, or near heat-sealing bars where standard seals would degrade.
Heavy Press & Forming
With 11045 N of force at 0.9 MPa, the SC125X100H suits small hydraulic-press replacements for punching, riveting, or die-casting trim operations, especially in hot environments.
Foundry & Forge Actuation
Deploy this cylinder for diverting heavy castings or operating furnace doors. The FKM seals resist radiant heat and aggressive airborne contaminants common in metal processing.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X100H the Right Cylinder?
Select the SC125X100H when your application needs high force at elevated temperatures. If the 6136 N push at 0.5 MPa is more than required, stepping down to an SC100 bore (3927 N at 0.5 MPa) can reduce air consumption and cost. For even higher force, the SC160 bore delivers 10053 N at the same pressure.
For a direct replacement, match these five points exactly: 125 mm bore, 100 mm stroke, PT port thread, basic mount (no accessory), and Viton seals. This cylinder does not include a magnet; if you need position sensing, select the -S variant and add compatible CMSG/DMSG sensors. For strokes over 300 mm, consider an external guide to protect the 32 mm rod from bending under side load.
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 SC125X100H FAQ
At 0.7 MPa operating pressure, the SC125 bore produces a theoretical push force of 8590 N. The pull force on the retract stroke is 5734 N due to the area reduction from the 32 mm piston rod.
Yes, the SC125X100H is dimensionally identical to the standard SC125X100. The only difference is the Viton (FKM) seal material, which extends the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C. All mounting accessories and port connections remain the same.
