About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-10
The AirTAC SAIJ160X250-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 240 to 250 mm. In this configuration, the 160 mm bore generates 10053 N of pull force at 0.5 MPa and up to 18095 N of push force at 0.9 MPa. The barrel features an extruded aluminum design with sensor grooves on both sides, and the piston rod is constructed from SUS304 stainless steel for superior corrosion resistance.
This specific SKU uses PT tapered port threads and incorporates a 10 mm external stopper at the rear cap. This stopper allows you to fine-tune the end position at commissioning without bolting on external stops or swapping the cylinder. The adjuster acts solely as a travel stop and does not lock the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-10 Is Used
Product Changeover Tuning
Dial in the 240-250 mm travel window during format changeovers on packaging lines without physically replacing the cylinder or adding external stopper blocks.
Heavy Press End-Positioning
Leverage the 18095 N push force at 0.9 MPa for heavy pressing operations, using the 10 mm rear adjuster to precisely set the bottom-dead-center contact point.
Corrosive Environment Actuation
Utilize the SUS304 stainless steel rod for robust performance in washdown or mildly corrosive manufacturing environments where carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-10 the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application requires a heavy force profile—delivering 10053 N pull at 0.5 MPa—and a precise 240-250 mm travel window. If your setup needs less force, stepping down to a 125 mm bore yields 5734 N of pull, whereas moving up to a 200 mm bore provides 15080 N. The 250 mm stroke falls below the 1500 mm maximum standard stroke, so no made-to-order surcharge applies.
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers or minor machine setup tweaks. Because the 250 mm stroke is below the 300 mm threshold, side-load stress on the 40 mm SUS304 rod is moderate, but an external guide is still recommended for heavy lateral loads. This model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ160BX250-10 FAQ
At 0.5 MPa, this 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 250 mm down to 240 mm. It only sets the travel end and does not hold the load without live air pressure.
