Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-50
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-50 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 SAIJ160X180-50
The AirTAC SAIJ160X180-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. It features a 40mm carbon steel rod and a G3/4 PT tapered port. By integrating an external stopper at the rear, this unit allows you to dial back the nominal 180mm stroke by up to 50mm, creating a precise 130-180mm usable travel window for exact end-position tuning.
This adjuster functions strictly as a mechanical travel stop to set the retract end position, not as a lock, meaning live air pressure is required to hold the load. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting hardware utilizes a reduced SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-50 Is Used
Heavy Press Fine-Tuning
Dial in the exact 130-180mm retract position on heavy pressing tasks without swapping out the entire cylinder or adding external mechanical stops.
Product Line Changeover
Quickly adjust the end-stop distance by up to 50mm when switching between product sizes on a high-force assembly line.
Automated Clamp Positioning
Set precise clamping depths at commissioning, using the robust 40mm carbon steel rod to handle substantial side loads in industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-50 the Right Cylinder?
Select this 160mm bore when an application demands heavy thrust but requires on-the-fly end-position tuning during commissioning or product changeovers, avoiding the need to physically swap cylinders or bolt on external stops. If your force requirements are lower, stepping down to a 125mm bore yields 8590N of push force at 0.5 MPa, whereas moving up to a 200mm bore provides 15708N at the same pressure. Because the 180mm stroke is relatively short for this large bore, side-loading is less pronounced, but external guides remain recommended for optimal rod bearing life.
For a drop-in ISO 15552 replacement, match the 160mm bore, 180mm stroke, 50mm adjustment range, G3/4 PT port, and appropriate mounting bracket. Note that this base configuration uses a carbon steel rod without a magnet; adding an -S magnet enables use with AirTAC CMSE reed and DMSE electronic solid-state sensors. If pneumatic pressure loss occurs, the rear stopper cannot hold the load—consider an AirTAC SAIL or BSAI locking cylinder for fail-safe load holding.

- ✓ 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 SAIJ160X180-50 FAQ
At an operating pressure of 0.7 MPa, this 160mm bore cylinder provides a push force of 14074N and a pull force of 9425N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 180mm nominal stroke by up to 50mm, providing a usable travel window of 130-180mm. It only sets the end position and does not lock the load without live air pressure.
