About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-30
The AirTAC SAIJ160X275-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 14074N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This specific SKU features a 275 mm nominal stroke that can be fine-tuned down by up to 30 mm, yielding a usable travel window of 245-275 mm. Configured with a SUS304 stainless steel rod (code B) and PT tapered ports, it is built for demanding environments. The rear adjuster acts purely as a travel stop for end-position tuning and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-30 Is Used
Heavy Press Tuning
Dial in the exact 245-275 mm end-stop during heavy press commissioning to accommodate material thickness variations without machining new stopper blocks.
Product Changeovers
Adjust the retract position on the fly when switching between different pallet sizes on a high-thrust conveyor sorting line.
Large Fixture Setup
Fine-tune the clamping distance on large machining fixtures, utilizing the 10053N pull force at 0.5 MPa to secure heavy workpieces.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-30 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high force combined with on-the-fly end-position tuning; stepping down to a 125 mm bore drops the 0.7 MPa push force to 8590N, while moving up to 200 mm increases it to 21991N. The adjustable 245-275 mm window is ideal for product-size changeovers on a line, allowing you to dial in the exact retract distance without swapping the cylinder or adding external stops. Because the stroke is 275 mm, an external guide should be used to support the load and mitigate side-load on the rod. For load-holding without live pressure, pair this cylinder with an external rod lock or look to the SAIL or BSAI series.
To match this ISO 15552 dimensionally interchangeable cylinder for replacement, confirm the 160 mm bore, 275 mm stroke, 30 mm adjustment range, PT port thread, and the SUS304 stainless steel rod material. Note that SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ160BX275-30 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074N and a pull force of 13234N. At 0.5 MPa, the push force is 10053N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a usable travel window of 245-275 mm from the 275 mm nominal stroke. It functions as a mechanical stop for position tuning and requires live air to hold the load.
