About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-100
The AirTAC SAIJ160X260-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074 N of push force at 0.7 MPa. Its 260 mm nominal stroke can be dialed back by up to 100 mm, yielding a highly flexible 160-260 mm usable travel window. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
This heavy-duty unit features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-100 Is Used
Heavy Press Tuning
Dial in the exact 160-260 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without mechanical rework.
Product Changeover
Adapt diverter stroke lengths on the fly during production line size changeovers, utilizing the 100 mm adjustment range to handle multiple package sizes.
Variable End Positioning
Set precise retraction points for large material handling actuators, ensuring delicate parts are engaged safely without adding bulky external stoppers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-100 the Right Cylinder?
Choose this 160 mm bore when an application requires substantial thrust—such as 14074 N push at 0.7 MPa—and a variable end-stop for product changeovers. If your process demands less force, stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa. The adjustable stroke is ideal for fine-tuning machine setup, whereas a fixed SAI cylinder is preferred for dedicated, single-cycle tasks.
Because this unit features a 260 mm stroke, the 40 mm rod diameter and M36x2 thread provide robust support, though an external guide is recommended to manage side loads on longer travels. For load-holding without live air, this plain cylinder is insufficient; consider an AirTAC SAIL lock or BSAI clamp-lock cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX260-100 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the 260 mm nominal stroke by up to 100 mm, creating a 160-260 mm usable window. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
