About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-30S
The AirTAC SAIJ80X130-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you dial back the nominal 130 mm travel to a precise 100-130 mm window during commissioning. It delivers 2513 N of pull force at 0.5 MPa and up to 4523 N at 0.9 MPa. The built-in adjuster acts purely as a mechanical stop to fine-tune the retract end position, meaning it cannot hold the load without live air pressure.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE or DMSE sensors. The extruded aluminum barrel carries sensor grooves on both sides, and the G3/8 ports manage airflow for a 30-800 mm/s speed range. It uses the standard SAIJ mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ80BX130-30S Is Used
Changeover Positioning
Dial in the exact retract distance from 100 to 130 mm during machine setup for different product sizes without physically replacing the actuator.
End-Stop Tuning
Fine-tune the final end position at commissioning using the rear screw stopper, eliminating the need to bolt on custom external shims or stops.
Variable Stroke Clamping
Adjust the clamping travel window on the fly for parts of varying heights, relying on the 25 mm SUS304 rod to handle side loads during the transition.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-30S the Right Cylinder?
The adjustable stroke is ideal for product changeovers where exact end-of-stroke positioning varies, saving you from swapping a fixed-stroke SAI cylinder or adding external stops. For load-holding without continuous air pressure, select a SAIL or BSAI series cylinder instead, as the SAIJ adjuster is a stop, not a lock.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 130 mm stroke, 30 mm adjustment, PT tapered G3/8 port, and the -S magnet requirement. Because this is a profile cylinder rather than a tie-rod type, it integrates cleanly into standard machine footprints using the available mounting brackets.

- ✓ 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 SAIJ80BX130-30S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 100 to 130 mm, allowing precise end-position tuning without swapping the cylinder.
At 0.9 MPa, the push force increases to 4523 N.
