About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-30
The AirTAC SAIJ80X130-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the travel end-position during commissioning. By turning the external stopper screw, you can shorten the nominal 130 mm stroke by up to 30 mm, creating a highly flexible 100-130 mm usable travel window without needing to swap out the barrel or add external stops.
This model is configured with a SUS420J2 stainless steel rod (option A) for enhanced resistance against surface corrosion in humid or mildly aggressive environments. The extruded aluminum barrel incorporates sensor grooves on both sides for mounting position detectors, though this specific SKU omits the internal magnet, meaning reed or electronic switches cannot be used without a magnet-equipped variant. The adjuster acts purely as a mechanical travel stop to set deceleration alongside the built-in air cushions; it does not lock or hold the load without continuous live air pressure.

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 SAIJ80AX130-30 Is Used
Variable End-Stop Setup
Dial in the exact clamping position within the 100-130 mm window during initial machine commissioning to accommodate varying workpiece heights without changing hardware.
Product Changeover
Quickly reposition the rear stopper screw on the production line when switching to a different product size, reducing downtime and eliminating the need for custom spacer shims.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-30 the Right Cylinder?
The rear stopper mechanism allows you to dial in the exact 100-130 mm travel distance required, preventing the need to maintain a large inventory of fixed-stroke SAI cylinders for every minor variation in part size. When matching this ISO 15552 cylinder for a replacement, verify the 80 mm bore, 130 mm nominal stroke, 30 mm adjustment range, PT tapered port threading, and the SUS420J2 stainless steel rod material.
Because the nominal stroke of 130 mm is relatively short, the 25 mm piston rod and M20x1.5 rod thread provide excellent rigidity and side-load capacity without requiring an external guide. Remember that the rear adjuster and the variable air cushions at both ends only serve to define the travel end and decelerate the load; they do not function as a brake. If your application requires true load-holding in the event of air pressure loss, you must integrate an external rod lock or pilot-operated check valve, or select an AirTAC SAIL or BSAI clamp-lock cylinder instead.
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.
