About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75
The SC160X75 is a double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa (18095 N at 0.9 MPa), making it a workhorse for heavy industrial clamping and pressing tasks. Its 75 mm stroke is paired with a robust 40 mm diameter piston rod and an adjustable air cushion (29 mm length) to decelerate the high-inertia load smoothly.
With a body length A of 239 mm, this genuine AirTAC actuator keeps overall dimensions compact for its force class. The PT3/4 port supplies ample flow for fast cycling, while the standard TPU seals provide reliable service from -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75 Is Used
Heavy Press Tool Actuation
Provides up to 18095 N of thrust at 0.9 MPa for stamping, riveting, or die-press ejection mechanisms requiring a short, powerful stroke.
Pallet & Container Lifting
Delivers 9425 N of pull force at 0.5 MPa to raise and lower heavy pallet corners or lift tables in logistics and material handling stations.
Automated Clamping Fixtures
Used in welding and assembly jigs where 10053 N of clamping force at standard shop air pressure securely holds large fabrications during processing.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X75 the Right Cylinder?
For applications needing slightly less force, the SC125 bore offers 6136 N at 0.5 MPa; for maximum push, step up to the SC200 bore at 15708 N. This SC160X75 is a basic configuration with PT thread and no magnet, so ensure your replacement matches bore, stroke, PT3/4 port, and basic mounting.
Even at a short 75 mm stroke, the 40 mm rod resists bending well, but any significant side load should be managed with an external guide rail to protect the rod bearing and seals from premature wear.
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 SC160X75 FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At the maximum operating pressure of 0.9 MPa, push force reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf.
No. As a standard double-acting cylinder, it does not lock or hold position when air is exhausted or pressure is lost. If load holding is required, you must add a pilot-operated check valve or an external mechanical rod lock.
