About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-40
The AirTAC SAIJ160X300-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 260 to 300 mm, allowing you to dial back the nominal stroke by up to 40 mm during commissioning. The extruded aluminum barrel integrates sensor grooves on both sides for flexible switch placement.
Delivering 10053 N of pull force at 0.5 MPa and 14074 N at 0.7 MPa, this heavy-duty unit is equipped with a robust 40 mm SUS304 stainless steel rod (code B) and a PT tapered G3/4 port. The rear adjuster acts purely as a mechanical stop to fine-tune the end position; it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-40 Is Used
Variable End-Stop Forming
Dial in the exact retraction point between 260 and 300 mm for high-force pressing or forming tasks that require frequent product-size changeovers.
Heavy Fixture Alignment
Fine-tune the end position during machine setup without bolting on external stops, relying on 14074 N of push force at 0.7 MPa to shift heavy fixtures.
Large Assembly Tuning
Adjust the travel window on the fly for large-component assembly lines, using the 40 mm SUS304 rod to handle significant mechanical stress.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-40 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial thrust combined with variable end-stops for product-size changes. If you need less force, stepping down to the 125 mm bore yields 5734 N of pull at 0.5 MPa. Conversely, moving up to the 200 mm bore provides 15080 N of pull. Because the 300 mm stroke creates an extended lever arm, an external guide is recommended to prevent excessive side-loading on the 40 mm rod thread.
The adjustable rear screw allows precise end-position tuning without swapping the cylinder or adding external stops. For true load-holding without live air, consider the SAIL (air-released lock) or BSAI (clamp-lock) series instead. This SAIJ configuration is dimensionally interchangeable per ISO 15552, featuring a PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet.
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 SAIJ160BX300-40 FAQ
At 0.5 MPa it provides 10053 N of pull force and 14074 N at 0.7 MPa. The maximum operating pressure is 1.0 MPa.
The rear adjuster acts as a mechanical stop that trims the effective travel, providing a usable stroke window of 260 to 300 mm. It decelerates the end of travel but does not lock the load without continuous air pressure.
