About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-30S
The AirTAC SAIJ80X90-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the 90 mm nominal travel by up to 30 mm for a precise 60-90 mm usable window. Delivering 2513 N of push force at 0.5 MPa, it is built with a corrosion-resistant SUS420J2 stainless steel rod and a PT tapered port thread. An integrated magnet allows position detection across the dual-side sensor grooves.
The rear adjuster acts as a mechanical stop to fine-tune the retract end position during commissioning without swapping cylinders or adding external stops. It is not a locking device; the standard adjustable air cushions at both ends manage end-of-stroke deceleration. For position holding without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-30S Is Used
Product Changeovers
Dial in the exact 60-90 mm retract stop during format changes without disassembling the machine or swapping the actuator.
Variable End Stops
Adjust the stroke on the fly to push different carton sizes to precise marking positions on a packaging line.
Commissioning Setup
Fine-tune the final end position during initial machine setup to align tooling perfectly, compensating for mechanical tolerances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX90-30S the Right Cylinder?
Choose this 80 mm bore when a 50 mm cylinder (982 N push at 0.5 MPa) lacks the power to move your load, but you want to avoid the larger fluid consumption of a 100 mm bore. The 30 mm adjustment range is ideal for product changeovers on a line where the exact retract position shifts slightly between batches. Since this is a standard 90 mm stroke, no external side-load guide is strictly required, but the 25 mm rod and M20x1.5 thread provide robust mechanical stability for moderate off-center loads.
To match this ISO 15552 interchangeable cylinder, specify: 80 mm bore, 90 mm stroke, 30 mm adjustment, PT ports, and the -S magnet for CMSE reed or DMSE electronic sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found on other models.
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 SAIJ80AX90-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you mechanically shorten the 90 mm nominal stroke by up to 30 mm, creating a 60-90 mm usable travel window. It functions as a hard stop for end-position tuning and does not lock the load when air is removed.
