About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-30
The AirTAC SAIJ80X200-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel within a 170 to 200 mm window. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
This variant incorporates a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and features PT tapered port threads with a G3/8 connection. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it is not a locking device and will not hold a 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 SAIJ80AX200-30 Is Used
Product Changeovers
Dial in the 170-200 mm travel window during format size changes on a packaging line without physically swapping the actuator.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve exact material positioning using the rear adjustment screw.
Assembly Pressing
Leverage the 2513 N pull force at 0.5 MPa for pressing tasks while adjusting the stroke to accommodate varying part heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-30 the Right Cylinder?
Choose this 80 mm bore when an application requires more force than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but does not need the full capacity of a 100 mm unit. The 30 mm adjustment range is ideal for product changeovers on a line, allowing operators to dial in the exact end position without swapping cylinders or adding external stopper blocks. For load-holding requirements without live air, consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI series cylinders.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 200 mm nominal stroke, 30 mm adjustment code, G3/8 PT ports, and desired mounting accessory. SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because this unit lacks a magnet (-S), it requires external physical sensors or a later upgrade to a magnet-equipped rod for CMSE or DMSE switches.
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 SAIJ80AX200-30 FAQ
The rear adjuster allows you to shorten the nominal 200 mm stroke by up to 30 mm, providing a usable travel window of 170 to 200 mm. It functions as a mechanical stop for end-position tuning and is not a lock.
At 0.9 MPa, the push force increases to 4523 N.
