About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-30
The AirTAC SAIJ80X600-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm, creating a precise 570-600 mm usable window. Delivering 2513 N of push force at 0.5 MPa, it handles heavy loads with a 25 mm SUS304 stainless steel rod that maximizes side-load resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model uses PT tapered ports (G3/8) and variable air cushions at both ends to manage deceleration. The rear stopper mechanism allows fine end-position tuning at commissioning without swapping out the entire cylinder or adding external stops. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-30 Is Used
Product Changeovers
Dial in the 570-600 mm travel window during format size changes on a packaging line without swapping cylinders or adding external stopper blocks.
Machine Setup
Fine-tune the retract end-position at commissioning to achieve precise mechanical alignment, absorbing tolerance variations across the fixture.
Variable End Stops
Adjust the effective stroke dynamically for automated processes that require slightly different retract distances based on the workpiece.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-30 the Right Cylinder?
Choose this 80 mm bore when a 63 mm cylinder (providing 1559 N push at 0.5 MPa) cannot meet your thrust requirements, or step up to a 100 mm bore if you need 3927 N. The adjustable stroke is ideal for product-size changeovers on a line, letting operators dial in the exact end-stop without replacing hardware. Because the nominal stroke is 600 mm, an external guide is strongly recommended to prevent excessive side-loading on the extended rod.
The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 dimensionally interchangeable cylinder, specify the 80 mm bore, 600 mm stroke, 30 mm adjustment, PT port thread, SUS304 rod, and no magnet.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80BX600-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 600 mm nominal stroke by up to 30 mm, providing a usable travel window of 570-600 mm. It sets the end position but does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ80X600-30 provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
