About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10S
The AirTAC SAIJ160X180-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 170-180 mm usable travel window, allowing you to dial back the nominal 180 mm stroke by up to 10 mm during commissioning without adding external stops. Equipped with a magnetic piston for position detection, it integrates seamlessly with CMSE reed and DMSE electronic sensors fitted into the dual-side extruded aluminum barrel grooves.
Built for heavy-duty performance, this 160 mm bore unit delivers 14074 N of push force at 0.7 MPa and utilizes a robust 40 mm carbon steel rod with an M36x2 thread. The PT tapered port design ensures a tight pneumatic seal, while variable air cushions at both ends manage deceleration. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10S Is Used
Heavy Press Tuning
Dial in the exact 170-180 mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping tooling.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm on automated assembly lines when switching between similar product sizes.
Large Fixture Positioning
Position large industrial fixtures with 14074 N of force at 0.7 MPa while using the fine-tune adjuster to set the precise retraction point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X180-10S the Right Cylinder?
Select this specific adjustable-stroke model when an application requires exact end-position tuning on a heavy fixture, avoiding the need to swap cylinders or bolt on external stops during product changeover. If your process needs slightly less force, stepping down to a 125 mm bore yields 8590 N at 0.5 MPa; stepping up to a 200 mm bore provides 21991 N at 0.7 MPa. Because the 180 mm stroke is under the 300 mm threshold, side-load stress is moderate, but the heavy 40 mm rod still requires an external guide for optimal bearing life.
For an exact ISO 15552 replacement, match the 160 mm bore, 180 mm stroke, 10 mm adjustment range, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets. Remember that neither the rear adjuster nor the air cushions function as a lock; for fail-safe load holding without live air, specify an external rod lock or choose the SAIL or BSAI cylinder series.
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 SAIJ160X180-10S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. The maximum allowable operating pressure is 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 180 mm down to 170 mm, creating a 170-180 mm usable window. This stopper only sets the end position and does not lock the load without live air.
