About the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210H
The SC125X210H is a large-bore double-acting pneumatic cylinder delivering 6136 N of push force at 0.5 MPa and up to 11045 N at 0.9 MPa. With a 210 mm stroke and a robust 32 mm piston rod, this ISO 6430 class tie-rod actuator is built for heavy industrial tasks where high force and thermal resilience are both required.
This variant is equipped with Viton (FKM) seals, extending its operating temperature range to 0–150 °C, making it suitable for hot environments such as foundries or drying lines. The adjustable air cushion (28 mm length) decelerates the piston smoothly, and the PT1/2 port supplies ample flow for the 125 mm bore.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210H Is Used
High-Temperature Clamping
Viton seals allow this cylinder to operate in ambient temperatures up to 150°C, making it ideal for clamping fixtures in baking ovens, autoclaves, or hot-forming presses.
Heavy Machinery Actuation
With over 11000 N of force at 0.9 MPa, the SC125X210H powers compactors, balers, and heavy-duty agricultural equipment, handling dense material compression reliably.
Foundry Pusher Stations
The combination of high force and heat-resistant seals suits pusher or ejector stations in foundries and steel mills, where standard seals would degrade quickly.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC125X210H the Right Cylinder?
For applications needing slightly less force, the 100 mm bore SC series provides 3927 N at 0.5 MPa. If higher force is required, stepping up to the 160 mm bore yields 10053 N at the same pressure. The SC125X210H is a tie-rod cylinder, shorter than an ISO 15552 profile, so direct replacement must match an existing AirTAC SC125 with identical 210 mm stroke, PT1/2 ports, basic mounting, and Viton seals.
With its 210 mm stroke, ensure the load is guided if side forces are present; the 32 mm rod is strong in compression but external guides prevent bearing wear from lateral loads.
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 SC125X210H FAQ
At 0.5 MPa (approx. 73 psi), the push force is 6136 N. At 0.7 MPa it rises to 8590 N, and at the maximum operating pressure of 0.9 MPa, it reaches 11045 N. The theoretical maximum at 1.0 MPa is 1251 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. It should only replace another AirTAC SC125 tie-rod cylinder with matching stroke, port thread (PT), and seal material.
