Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10
The AirTAC SAIJ80X350-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. It features a SUS420J2 stainless steel rod and PT tapered G3/8 ports. By integrating an external adjusting stopper, this actuator provides a usable travel window of 340-350 mm, allowing you to trim the effective stroke by up to 10 mm without swapping the cylinder.
This rear screw mechanism acts purely as a travel stop to fine-tune the end position during commissioning; it does not lock or hold the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting hardware utilizes the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10 Is Used
Product Changeovers
Dial in the 340-350mm travel window during format size changes on packaging lines, avoiding the need to physically swap out actuators for different product lengths.
Machine Setup
Fine-tune the retract end-position at commissioning to perfectly dial in mechanical stops, compensating for minor fixture misalignments without external shims.
Variable End Stops
Provide adjustable physical stops for diverter gates or pushing mechanisms where the exact end-of-stroke position needs occasional tweaking based on payload variations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10 the Right Cylinder?
Select this 80mm bore actuator when an application requires moderate thrust and precise end-position tuning. If your setup demands less force, stepping down to a 63mm bore yields 1559N of push force at 0.5 MPa, whereas moving up to a 100mm bore provides 3927N. The adjustable stroke is ideal for product changeovers on a line, offering variable end-stops instead of relying on a fixed-stroke SAI cylinder. Because the nominal stroke is 350mm, the 25mm rod and M20x1.5 thread handle substantial side loads, but an external guide is still recommended for unsupported lengths. To replace an ISO 15552 cylinder, match the 80mm bore, 350mm stroke, 10mm adjustment, PT G3/8 port, and mounting style. Note that for load-holding without pneumatic pressure, you must use a SAIL lock, BSAI clamp-lock, or external rod lock, as this adjuster is not a brake.
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 SAIJ80 Adjustable Cylinder SAIJ80AX350-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective travel from the 350mm nominal stroke down to 340mm. This creates a 340-350mm usable window for fine-tuning the end position at commissioning, but it acts only as a stop and does not hold the load without continuous air pressure.
