About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-30S
The AirTAC SAIJ80X450-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This built-in adjustability allows you to dial in exact end positions during commissioning without adding external stops.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet (-S) for position sensing. It operates at 30-800mm/s and uses a PT G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX450-30S Is Used
Product Changeover
Quickly shift the retract end-stop by up to 30mm during packaging line format changes without replacing the cylinder or bolting on external stops.
Machine Setup
Fine-tune the 420-450mm travel window during commissioning to perfectly time the stroke endpoint for critical machining or clamping operations.
Variable End Positioning
Dial in the exact retract position for automated assembly equipment, accommodating slight variations in part dimensions using the rear stopper.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-30S the Right Cylinder?
The adjustable stroke is ideal for product changeovers on a line, letting you shift the retract end-stop by up to 30mm without swapping the cylinder. Because the 450mm stroke is relatively long, an external guide is recommended to support the load and prevent excessive side-loading on the SUS304 rod.
When specifying a replacement, match the 80mm bore, 450mm stroke, 30mm adjustment, PT G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80BX450-30S FAQ
The rear adjuster acts as a mechanical stop that trims the effective stroke. For this SAIJ80X450-30-S model, you can shorten the 450mm nominal stroke by up to 30mm, yielding a usable travel window of 420-450mm to fine-tune the end position.
