About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225SH
The SC125X225SH is a robust double-acting pneumatic cylinder delivering a push force of 6136 N at 0.5 MPa and up to 11045 N at 0.9 MPa operating pressure. Its 32 mm diameter piston rod and 225 mm stroke suit medium-travel, high-force clamping and pressing tasks in demanding thermal environments.
This model features a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke detection. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it ideal for autoclaves, foundries, or hot press applications where standard seals would degrade.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225SH Is Used
High-Temperature Presses
Viton seals allow reliable operation in heated platen presses and thermoforming machines up to 150°C, where standard cylinders fail.
Heavy-Duty Clamping
With 11045 N of force at 0.9 MPa, this cylinder provides secure, sensor-verified clamping for welding fixtures and large assembly jigs.
Autoclave & Sterilization
The FKM seals and magnetic piston sensing make it suitable for actuating doors or valves in high-temperature sterilization and chemical processing equipment.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X225SH the Right Cylinder?
For applications needing slightly less force, the 100 mm bore SC series provides 3927 N push at 0.5 MPa. If greater force is required, step up to the 160 mm bore which delivers 10053 N. Always match replacement cylinders across five key points: bore (125 mm), stroke (225 mm), PT port thread, the built-in magnet (-S), and Viton seal material (-H).
With a 225 mm stroke, this ISO 6430 class cylinder operates within standard limits. However, any side loading should be managed with an external guide system to protect the rod bearing and ensure long service life.
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 SC125X225SH FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. The maximum operating force at 0.9 MPa is 11045 N push. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so it is not dimensionally interchangeable. It must replace another AirTAC SC tie-rod cylinder with identical bore, stroke, port type, magnet option, and seal material.
