About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350
The AirTAC SC160X350 is a robust double-acting tie-rod cylinder delivering a substantial 10053 N of push force at 0.5 MPa (18095 N at 0.9 MPa). With a 160 mm bore and a 350 mm stroke, this model is built for heavy linear actuation tasks where high force and reliability are paramount.
The piston rod measures 40 mm in diameter with an M36x2 knuckle thread, providing excellent rigidity for demanding push/pull applications. The cylinder body length (A) is 239 mm, and the unit features a 29 mm adjustable air cushion at each end to decelerate high-inertia loads smoothly, reducing end-of-stroke impact.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350 Is Used
Heavy Press Tool Actuation
Provides the high clamping and pressing forces required in metal forming and stamping operations, with smooth cushioning to protect tooling.
Material Handling Pushers
Ideal for pushing heavy pallets, logs, or scrap material on conveyors, leveraging the 10053 N push force at standard 0.5 MPa line pressure.
Large Damper & Gate Control
Operates heavy ventilation dampers or hopper gates in processing plants, where the robust 40 mm rod withstands high back-pressure and frequent cycling.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X350 the Right Cylinder?
Select the SC160X350 for applications needing the 10 kN force class at standard plant pressure. If your load requires slightly less force and a lighter assembly, consider stepping down to the SC125 bore (6136 N push at 0.5 MPa). For strokes of 350 mm, ensure the rod is guided externally if significant side loads are present; the 40 mm rod is strong, but long unsupported strokes under lateral force can cause bearing wear and rod bending.
To replace an existing cylinder, match five key points: 160 mm bore, 350 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and the standard TPU seal. This is a tie-rod cylinder and will directly replace another AirTAC SC160 of the same configuration.
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 SC160X350 FAQ
At 0.7 MPa operating pressure, the SC160X350 produces 14074 N of push force on the piston and 9425 N of pull force on the retract stroke, based on the official AirTAC thrust table for the 160 mm bore.
No. The SC160X350 is a standard double-acting cylinder and will not hold position if air pressure is exhausted or lost. The adjustable air cushion only decelerates the piston at stroke end; it does not lock the rod. For load holding, you must add an external rod brake or a pilot-operated check valve.
