About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-30
The AirTAC SAIJ80X700-30 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 670-700 mm usable window for precise end-position tuning. It delivers a robust 2513 N pull force at 0.5 MPa, making it well-suited for heavy handling tasks. The extruded aluminum barrel includes sensor grooves on both sides, and this specific configuration features a SUS420J2 stainless steel rod and PT tapered port threads.
The rear adjuster acts purely as a mechanical stop to fine-tune the stroke during commissioning or product changeover, saving you from swapping the cylinder or adding external stops. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Note that the adjuster and air cushions decelerate the load but do not hold it without live air; for position holding, consider the SAIL or BSAI series.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-30 Is Used
Product Changeover Lines
Dial in the 670-700 mm travel window during format size changes without physically swapping out long-stroke actuators on the conveyor.
Machine Setup Tuning
Fine-tune the retract end-position during initial commissioning to perfectly align heavy 2513 N loads without adding external stopper blocks.
Variable End-Stop Assembly
Use the rear adjuster to tweak the final resting position of tooling on the fly, ensuring precise alignment for varying part dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX700-30 the Right Cylinder?
Choose this 80 mm bore when you need higher force than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but do not require the massive output of a 100 mm unit. The adjustable stroke is ideal for variable end-stops and machine setup, offering more flexibility than a fixed-stroke SAI cylinder. When replacing an ISO 15552 cylinder, match the 80 mm bore, 700 mm stroke, 30 mm adjustment, PT G3/8 port, and appropriate mounting. Because the stroke is 700 mm, the 25 mm rod diameter should be supported by an external guide to prevent excessive side-loading on the barrel seals.

- ✓ 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 SAIJ80AX700-30 FAQ
At the maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the 700 mm nominal stroke by up to 30 mm, providing a usable travel window of 670 to 700 mm. It acts as a mechanical stop to tune the end position and does not lock the load without live air pressure.
