About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X35
The SC160X35 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a substantial push force of 10053 N at 0.5 MPa (up to 18095 N at 0.9 MPa). With a 160 mm bore and a short 35 mm stroke, it is built for applications requiring high clamping or pressing force within a very compact linear envelope.
This model features a 40 mm diameter piston rod with an M36x2 male thread and PT3/4 port connections. The cylinder body length A is 239 mm, resulting in a total extended length of approximately 274 mm. It includes an adjustable pneumatic cushion (29 mm length) to decelerate the piston smoothly at end-of-stroke, protecting the end caps from impact.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X35 Is Used
Heavy-Duty Clamping
The 10053 N force at 0.5 MPa makes this cylinder ideal for powerful jigs and fixtures that need to lock workpieces in place for machining or welding with a short, decisive stroke.
Press-Fit Assembly
Delivers up to 18095 N of thrust at 0.9 MPa for pressing bearings, bushings, or pins into housings where a short 35 mm insertion depth is required.
Material Stamping
Suitable for small-scale stamping or embossing operations that demand high force over a limited travel distance, ensuring consistent repeatability in a compact footprint.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X35 the Right Cylinder?
Choose the SC160X35 when you need the high force capacity of a 160 mm bore but only a minimal working stroke. If your application requires slightly less force in a smaller package, stepping down to the 125 mm bore (6136 N push at 0.5 MPa) may be suitable. For longer strokes up to 1500 mm, the SC160 series remains the correct choice.
To ensure a direct replacement, match five key attributes: bore (160 mm), stroke (35 mm), port thread (PT3/4), mounting style (basic, no bracket), and the presence or absence of a magnet (this model has no built-in magnet). Always verify the overall extended length (A + stroke) fits the available space, as the SC tie-rod body is shorter than a typical ISO 15552 profile.
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 SC160X35 FAQ
At the standard operating pressure of 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, the push force increases to 18095 N. The theoretical maximum force at 1.0 MPa is 2050 kgf.
No. The SC160X35 is a double-acting cylinder that requires continuous air pressure to maintain its position. If pressure is lost or the directional valve is centered, the piston will drift. For load-holding, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
