About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-100
The AirTAC SAIJ160X900-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 800-900 mm during commissioning. Equipped with a robust 40 mm SUS420J2 stainless steel rod and G3/4 PT tapered ports, it delivers exceptional thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa. This made-to-order 900 mm stroke configuration utilizes the maximum standard stroke limit for the 160 mm bore, ensuring precise end-position tuning without the need for external stops.
Because the rear adjuster functions strictly as a travel stop and not a lock, the cylinder relies on live air to maintain its position. For load-holding without continuous air pressure, you would need to explore related series like the SAIL or BSAI. This model omits the FB, CA, CB, and CR mounting options, utilizing a focused ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) to simplify machine integration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-100 Is Used
Product Size Changeovers
Dial in the 800-900 mm travel window on the fly to accommodate varying package lengths on a packaging line without swapping hardware.
Heavy Machinery Setup
Fine-tune the end-stop position during initial machine commissioning to perfectly time the 14074 N push force against heavy structural stops.
Long-Stroke Material Handling
Utilize the 900 mm stroke for pushing heavy pallets or workpieces, relying on the external guide to manage side loading while the adjuster sets the exact retraction depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-100 the Right Cylinder?
Choose this 160 mm bore adjustable cylinder when your application requires the 14074 N of push force available at 0.7 MPa, stepping up significantly from the 63 mm bore which provides 2182 N. The 100 mm adjustment window is specifically beneficial for product size changeovers on a line, allowing operators to dial in the exact end-stop without physically swapping out the entire cylinder for a shorter stroke variant.
When replacing an ISO 15552 cylinder, verify the 160 mm bore, 900 mm stroke, 100 mm adjustment range, G3/4 PT ports, and the required mounting style. Because this unit features a 900 mm stroke, the 40 mm rod diameter will carry substantial side loads, but an external guide rail is still highly recommended to prevent premature seal wear. Note that this variant lacks a magnet for position sensing.
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 SAIJ160AX900-100 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 900 mm down to 800 mm. It is a travel stop for end-position tuning, not a lock, so the cylinder still requires live air to hold the load.
