About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-30
The AirTAC SAIJ80X200-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel to anywhere within a 170-200 mm window. The extruded aluminum barrel features sensor grooves on both sides, though this specific SKU omits the magnet.
This configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The rear stopper lets you dial in the exact end position during commissioning without adding external stops. Remember that this adjuster acts only as a travel stop, not a load lock; maintaining position requires continuous 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 SAIJ80BX200-30 Is Used
Machine Changeover
Quickly shift the retract end-position by up to 30 mm when adapting machinery to a new product size, eliminating the need to physically swap cylinders.
End-Position Tuning
Dial in the exact 170-200 mm travel distance during initial commissioning to perfect a pressing or forming operation without external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-30 the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers on a packaging line, letting operators shift the retract end-position dynamically rather than swapping out a fixed-stroke SAI cylinder. To match this ISO 15552 footprint exactly, specify an 80 mm bore, 200 mm stroke, PT G3/8 port, and SUS304 rod material.
With a 200 mm stroke, the 25 mm rod diameter provides good rigidity, but any long unsupported piston travel still requires an external guide to prevent excessive side-loading. Mounting options for this series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. If your process needs to hold a load without live air, consider the SAIL or BSAI locking cylinders instead of relying on the rear stopper.
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 SAIJ80BX200-30 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the nominal 200 mm stroke by up to 30 mm, providing a usable travel window of 170-200 mm. It only sets the end-of-travel position and does not lock the load without live air pressure.
