About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-30
The AirTAC SAIJ160X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 18095N and pulling 9425N at 0.9 MPa, making it suited for heavy-duty operations. The extruded aluminum barrel includes sensor grooves on both sides, though this standard carbon steel rod version omits the magnet for CMSE or DMSE switches.
Equipped with a 30 mm adjustment range, this model allows you to fine-tune the effective travel down from its 180 mm nominal stroke, creating a usable 150-180 mm window. This built-in adjustability is ideal for dialing in end positions during commissioning without adding external stops. The rear mechanism acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-30 Is Used
Heavy Press Tuning
Dial in the exact 150-180 mm travel window during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Quickly adjust the retract end-stop by up to 30 mm on automated assembly lines when switching between different product sizes.
Robotic End Effectors
Provides a robust 18095N push force for large robotic gripping arms, allowing precise rear-position calibration for delicate part placement.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-30 the Right Cylinder?
Choose this 160 mm bore when a 125 mm bore (providing 11045N push at 0.9 MPa) is insufficient, but a massive 200 mm bore is too large for your footprint. The SAIJ160X180-30 is selected when exact end-of-stroke positioning is critical; the 30 mm rear adjuster allows on-the-fly tuning during product changeovers, unlike a fixed-stroke SAI cylinder. Because the 180 mm stroke is under the 300 mm threshold, side-load risks are minimal, though the robust 40 mm rod and M36x2 thread handle substantial forces. Remember, the adjuster is a stop, not a lock; for true load-holding without live air, use an external pilot-operated check valve or explore the SAIL or BSAI series. This configuration uses PT tapered ports and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ160X180-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. It can deliver a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 30 mm, providing a usable travel window of 150-180 mm. This allows fine-tuning of the retract end position at commissioning without external stops; the adjuster acts as a stop and does not lock the load without air pressure.
