About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-50S
The AirTAC SAIJ80X200-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 200 mm travel by up to 50 mm. This creates a usable 150-200 mm end-position window, enabling precise fine-tuning directly at commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports position detection via CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to set deceleration, not as a load lock.

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 SAIJ80AX200-50S Is Used
Product Size Changeovers
Quickly modify the effective stroke from 200 mm down to 150 mm to accommodate varying package sizes on a packaging line without changing hardware.
End-Position Tuning
Fine-tune the retract end-position at machine commissioning to ensure precise mechanical alignment, absorbing any minor variances in fixture height.
Variable End Stops
Use the 50 mm adjustment range to set deceleration points for different actuation sequences, relying on the rear stopper rather than adding external shock absorbers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-50S the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI when your machine setup requires variable end-stops or product-size changeovers, as the 50 mm adjuster allows rapid reconfiguration without physically swapping the cylinder. To replace an ISO 15552 cylinder, match the 80 mm bore, 200 mm stroke, 50 mm adjustment, PT G3/8 port, and -S magnet.
Because the stroke is 200 mm, the 25 mm rod and M20x1.5 thread provide solid resistance to side loads, though an external guide is recommended for heavy lateral loads. Remember that this plain SAIJ does not hold position without live air; for true load-holding without pressure, select an AirTAC SAIL or BSAI 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.
Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-50S FAQ
At the maximum pressure of 1.0 MPa, the push force reaches 513 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 50 mm, creating a usable travel window of 150-200 mm. It sets the travel end and deceleration point but does not lock or hold the load without live air pressure.
