Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-40
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-40
The AirTAC SAIJ160X90-40 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 90 mm stroke that can be mechanically dialed back by up to 40 mm, yielding a precise 50-90 mm usable travel window for exact end-position tuning. Belonging to the 160 mm bore class, it outputs 10053 N of pull force at 0.5 MPa and 14074 N of push force at 0.7 MPa.
This unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads alongside a robust M36x2 rod thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear adjuster allows you to set the travel end without adding external stops, it functions strictly as a deceleration stop and will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-40 Is Used
Heavy Press Tuning
Dial in the exact 50-90 mm travel window during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Rapidly adjust the retract end-stop on automated lines when switching product sizes, minimizing downtime by avoiding physical cylinder swaps.
Corrosive Assembly
Leverage the SUS304 stainless steel rod in washdown or corrosive manufacturing environments while maintaining precise 90 mm nominal stroke positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-40 the Right Cylinder?
Choose this 160 mm bore when your application requires heavy thrust—such as 10053 N pull at 0.5 MPa—and demands on-the-fly stroke tuning. If you need slightly less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa; conversely, moving up to a 200 mm bore provides 15080 N of pull. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the end stop during commissioning rather than swapping out a fixed-stroke SAI cylinder.
For an exact ISO 15552 replacement, match the 160 mm bore, 90 mm stroke, 40 mm adjustment range, PT G3/4 port, and SUS304 (B) rod material. Because this is a profile cylinder, it uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Although the 90 mm stroke is short, the heavy 40 mm diameter rod handles high side loads well; for longer unsupported strokes, always use an external guide. Remember that neither the rear adjuster nor the air cushions act as a lock—if you need true load-holding without live air, consider the SAIL or BSAI series.

- ✓ 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 SAIJ160BX90-40 FAQ
At 0.5 MPa operating pressure, the 160 mm bore provides 10053 N of pull force and 14074 N of push force. At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the nominal 90 mm stroke back by up to 40 mm, creating a usable travel window of 50 to 90 mm. It only sets the end position and decelerates the load; it does not lock or hold the load without live air pressure.
