About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-75
The AirTAC SAIJ80X600-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 25 mm rod and a robust 2513 N push force at 0.5 MPa, paired with a 600 mm nominal stroke that can be fine-tuned down by up to 75 mm. This yields a usable travel window of 525 to 600 mm, allowing precise end-position calibration without external stops.
This variant uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts strictly as a travel stop for deceleration, not a lock; the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-75 Is Used
Product Changeovers
Dial in the exact end-stop distance on packaging lines when switching between box sizes, utilizing the 525-600 mm travel window without changing hardware.
Machine Setup Tuning
Fine-tune the final retract position during equipment commissioning to achieve precise pressing or clamping alignment.
Variable End Stops
Adjust the stroke length dynamically on diverter gates to accommodate different product profiles on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-75 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) is insufficient, but a 100 mm bore (3927 N at 0.5 MPa) would be excessive. The 75 mm adjustment range is highly valuable for machine setups requiring frequent product-size changeovers, as it replaces the need to physically swap cylinders to achieve a shorter stroke. For load-holding without continuous air pressure, this standard SAIJ is not suitable; consider an SAIL air-released lock or BSAI clamp-lock cylinder instead.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 600 mm stroke, 75 mm adjustment, PT G3/8 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 600 mm stroke is long, the unsupported rod is prone to deflection; an external guide is strongly recommended to prevent excessive side-loading and premature seal wear.

- ✓ 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 SAIJ80AX600-75 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At the maximum pressure of 1.0 MPa, the push force reaches 5026 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm. This creates a usable travel window between 525 mm and 600 mm, enabling fine-tuning of the end position at commissioning without swapping the cylinder.
