About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-30
The AirTAC SAIJ80X210-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel, creating a usable window between 180 and 210 mm. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, meaning position sensing via CMSE or DMSE switches is not enabled without modification.
This SKU uses a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and carries an M20x1.5 rod thread. The rear adjuster functions purely as a mechanical stop to fine-tune the end position during commissioning without adding external stops; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ80BX210-30 Is Used
Changeover Adjustment
Dial in the exact 180 to 210 mm end-position during product size changeovers on a packaging line without swapping cylinders.
Machine Setup
Fine-tune the retract stop during initial commissioning to perfect a pressing or clamping operation.
Variable End Stops
Use the rear adjuster to set precise mechanical limits for repeatable actuation in automated assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-30 the Right Cylinder?
The adjustable 180-210 mm travel window is ideal for machine setups requiring variable end-stops or product-size changeovers, negating the need to swap out a fixed-stroke SAI cylinder. The PT tapered port thread matches the G3/8 air supply standard for this bore size.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 210 mm nominal stroke, 30 mm adjustment range, G3/8 PT port, and the correct mounting accessory. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, explicitly omitting FB, CA, CB, and CR brackets. Because the stroke exceeds 300 mm only on larger variants, this 210 mm stroke is safe from excessive rod sag, but always ensure external guidance for heavy lateral loads.
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 SAIJ80BX210-30 FAQ
At the maximum 1.0 MPa pressure, the push force reaches 5026 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 210 mm stroke by up to 30 mm. This creates a usable travel window of 180 to 210 mm for fine-tuning end positions.
