About the Airtac AIRTAC SC125-160 Standard Cylinder SC160X225
The SC160X225 is a double-acting tie-rod cylinder delivering 10053 N of push force at 0.5 MPa and up to 18095 N at the maximum operating pressure of 0.9 MPa. With a 225 mm stroke and a robust 40 mm diameter piston rod, this model is built for heavy linear actuation tasks where consistent thrust and reliable cycling are essential.
A 29 mm adjustable air cushion at each end decelerates the piston smoothly, reducing end-of-stroke impact and extending service life. The body length A measures 239 mm, giving a total extended length of approximately 464 mm. Ports are PT3/4 with an M36x2 rod thread, and the cylinder operates on filtered air from 0.15 to 1.0 MPa across a temperature range of -20 to +70 °C with its standard TPU seals.

Where the Airtac AIRTAC SC125-160 Standard Cylinder SC160X225 Is Used
Heavy Press & Clamping
The 18095 N thrust at 0.9 MPa makes the SC160X225 ideal for hydraulic-replacement clamping fixtures, forming presses, and heavy-duty assembly jigs where a compact pneumatic footprint is preferred.
Pallet & Product Transfer
With a 225 mm stroke and 40 mm rod, this cylinder reliably pushes heavy pallets or product carriers across transfer stations and lift-and-carry conveyor sections.
Industrial Gate & Damper Actuation
Use the SC160X225 to operate large diverter gates, hopper doors, or ventilation dampers in material handling and processing plants, where robust force and adjustable end-cushioning are critical.
Is the Airtac AIRTAC SC125-160 Standard Cylinder SC160X225 the Right Cylinder?
Select the SC160X225 when your application needs roughly 10000 N of force at standard shop air; for a lighter, more compact solution step down to the SC125 bore (6136 N push at 0.5 MPa), or move up to the SC200 bore (15708 N push at 0.5 MPa) if you require significantly higher thrust. The 225 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
To ensure a correct replacement, match five points: 160 mm bore, 225 mm stroke, PT3/4 port thread, the specific mounting accessory your machine uses (this basic-body model accepts the full F-SC160 range of feet, flanges, clevises, and trunnion kits), and whether a magnet is required for sensor mounting. For strokes of 300 mm or longer, always evaluate side-load conditions and consider an external guide or guided cylinder to protect the rod bearing from bending moments.
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 SC160X225 FAQ
At 0.5 MPa the push force is 10053 N and the pull force is 9425 N. At 0.7 MPa push rises to 14074 N, and at the maximum operating pressure of 0.9 MPa it reaches 18095 N. The theoretical maximum at 1.0 MPa is 2050 kgf (approx. 20100 N).
No. The SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder, so mounting dimensions and overall length will not match. It is a direct replacement only for another AirTAC SC160 tie-rod cylinder with the same stroke, port type, and mounting configuration.
