About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-20S
The AirTAC SAIJ160X90-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 90 mm travel back by up to 20 mm, creating a precise 70-90 mm usable end-position window. Delivering 18095 N of push force at 0.9 MPa, this 160 mm bore actuator handles heavy loads. The stainless SUS304 rod material provides superior corrosion resistance for harsh or washdown environments.
This unit includes a PT tapered port thread and a magnetic piston for position sensing. The rear adjuster acts purely as a travel stop for fine-tuning at commissioning; it does not lock the load without live air pressure. For safety-critical load holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-20S Is Used
Heavy Press Tuning
Dial in the exact 70-90 mm end-stop during machine setup to accommodate varying material thicknesses without mechanical rework.
Product Changeover
Rapidly adjust the retract position on automated lines when switching product sizes, using the 20 mm trim to fine-tune the stroke.
Washdown Actuation
Leverage the SUS304 stainless rod for corrosion resistance in food or chemical processing environments requiring high thrust.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX90-20S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore's 7068 N push at 0.9 MPa is insufficient, but step up to a 200 mm bore (28274 N) if your application requires extreme force. The adjustable 20 mm window is ideal for product changeovers, allowing you to dial in the exact end-stop without swapping cylinders or adding external shims.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 90 mm stroke, PT G3/4 ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Even though the stroke is under 300 mm, the heavy 40 mm rod and M36x2 thread handle high side loads, but an external guide remains essential for lateral stability.
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 SAIJ160BX90-20S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides 18095 N of push force and 9425 N of pull force. It reaches a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 90 mm stroke by up to 20 mm, providing a usable travel window of 70 to 90 mm. This stopper fine-tunes the end position but does not hold the load without live air pressure.
