About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X420
The SC160X420 is a double-acting tie-rod cylinder delivering substantial linear force, rated at 10053 N push and 9425 N pull when operated at 0.5 MPa. With a 160 mm bore and a 420 mm stroke, this model is built for heavy industrial tasks, using a robust 40 mm diameter piston rod and M36x2 knuckle thread for secure tooling attachment.
This cylinder features an adjustable pneumatic cushion (29 mm length) at both ends to decelerate the piston smoothly, reducing impact and noise. The body length A is 239 mm, giving a total extended length of approximately 659 mm. It uses PT3/4 ports and standard TPU seals for a working temperature range of -20 to +70 °C.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X420 Is Used
Heavy Press Tool Actuation
Provides the 10 kN class force needed for clamping and forming in large hydraulic-style press tools, using filtered plant air.
Pallet Lifting & Transfer
Handles heavy pallet lifting mechanisms in logistics hubs, where the 420 mm stroke moves loads between conveyor levels reliably.
Structural Test Rigs
Applies controlled, repeatable linear load in civil engineering material test frames, benefiting from the adjustable end-of-stroke cushion.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X420 the Right Cylinder?
Select the SC160X420 for applications needing high force in the 10 kN class at standard plant pressure. If your load requires less force, stepping down to the SC125 bore reduces push force to 6136 N at 0.5 MPa, saving air consumption. For even higher demands, the SC200 bore offers 15708 N at the same pressure.
For this 420 mm stroke, ensure the load is guided and side forces are eliminated; a 40 mm rod under high thrust can be damaged by bending moments. When replacing an existing cylinder, match five points exactly: 160 mm bore, 420 mm stroke, PT3/4 port thread, basic (no) mounting, and confirm the magnet option (this model has no built-in magnet).
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 SC160X420 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 SC160X420 is a double-acting cylinder and will drift or drop if air pressure is exhausted or the directional valve is centered. It does not have a mechanical lock. For load holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
