About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-100
The AirTAC SAIJ160X325-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. With a 160 mm bore, it generates 18095 N of push force at 0.9 MPa. The integrated adjuster allows you to fine-tune the effective travel anywhere within a 225-325 mm window, providing exact end-position calibration without swapping hardware. This unit features a SUS304 stainless steel rod for superior corrosion resistance and operates via PT threaded ports.
Because the nominal 325 mm stroke is relatively long, the 40 mm rod diameter and M36x2 rod thread provide essential rigidity, though an external guide is still recommended to manage side loads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to mount CMSE or DMSE switches if position feedback is needed later. Air cushions at both ends decelerate the heavy payload smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-100 Is Used
Heavy Press Tuning
Dial in the exact 225-325 mm end-stop during heavy press commissioning to accommodate material thickness variations without changing the cylinder.
Large Product Changeover
Adjust the rear stopper mechanically on the fly when switching between large product sizes on an assembly line, avoiding software recalibration.
Heavy Load Positioning
Move substantial payloads using the 18095 N push force while relying on the external stopper to set precise retraction limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-100 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial force that smaller bores cannot provide; stepping down to a 125 mm bore drops the 0.9 MPa push force to 11045 N. The 100 mm adjustment range is ideal for product changeovers on large machinery, letting operators dial in the exact end-stop mechanically without reprogramming fixed SAI cylinders. If your setup requires holding a load without live air pressure, note that this rear adjuster acts only as a travel stop and not a lock; you should explore an AirTAC SAIL or BSAI cylinder instead.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 325 mm nominal stroke, 100 mm adjustment range, G3/4 port size, and PT thread type. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Given the 325 mm stroke, ensure your mounting configuration includes an external guide to prevent excessive rod side-loading.

- ✓ 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 SAIJ160BX325-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. It can deliver a maximum force of 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 100 mm, creating a usable travel window of 225-325 mm. It only sets the travel end and does not lock the load without live air.
