Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 180mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10
The AirTAC SAIJ160X180-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial force, providing 10053N of pull at 0.5 MPa and up to 18095N of push at 0.9 MPa. With a nominal 180mm stroke and a 10mm adjustment range, the effective travel window can be precisely dialed back to 170mm during commissioning without adding external stops.
This heavy-duty actuator utilizes a robust 40mm carbon steel piston rod and a PT tapered G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification. The rear adjuster acts purely as a travel stop to fine-tune the retract end position and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10 Is Used
Heavy Machinery Setup
Fine-tune the 170-180mm travel window during heavy equipment assembly to achieve precise end-positioning without machining custom spacers.
Product Line Changeover
Dial back the retract stroke by up to 10mm to accommodate slightly different product lengths on an automated line.
High-Force Clamping
Utilize the 18095N push force at 0.9 MPa for heavy-duty clamping tasks where the exact clamp depth needs minor field adjustment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10 the Right Cylinder?
Select this 160mm bore actuator when an application requires high thrust combined with exact end-position tuning, stepping up from a 125mm bore that yields 6136N push at 0.5 MPa. The 10mm adjustable window is chosen over a fixed-stroke SAI cylinder when you need a variable end-stop to accommodate minor product size changes on a line without physically swapping the actuator. For load-holding without continuous air pressure, note that this adjuster is a stop and not a lock; you should look at the SAIL or BSAI series instead. To match an ISO 15552 replacement, ensure the 160mm bore, 180mm stroke, 10mm adjustment, PT G3/4 port, and standard carbon steel rod are specified. Because the stroke is under 300mm, side-load concerns are minimal, but the 40mm rod still handles substantial guide loads well.
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 SAIJ160 Adjustable Cylinder SAIJ160X180-10 FAQ
At 0.5 MPa, it provides 10053N of pull force and 14074N of push force. At the maximum operating pressure of 1.0 MPa, the push force reaches 2050 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 180mm down to 170mm. This creates a 170-180mm usable window for fine-tuning the retract end position at commissioning without swapping the cylinder.
