About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-30S
The AirTAC SAIJ80X210-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 210 mm stroke that can be dialed back by up to 30 mm, giving you a precise 180-210 mm usable travel window for fine-tuning end positions during commissioning.
This specific SKU is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply is via PT tapered G3/8 ports. The rear adjuster acts purely as a travel stop and does not hold the load without 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 SAIJ80BX210-30S Is Used
Variable End-Stop Tuning
Fine-tune the 180-210 mm travel window during machine setup to dial in exact positioning without changing the cylinder or bolting on external stops.
Product Size Changeover
Quickly adjust the rear stopper on a packaging line to accommodate different carton lengths or product sizes on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-30S the Right Cylinder?
The adjustable 180-210 mm window is ideal for product changeovers on a line, allowing you to reposition the end stop without swapping the cylinder or adding external stops. For load-holding without live air, select the SAIL or BSAI series instead, as the SAIJ adjuster is a stop, not a lock.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 210 mm stroke, 30 mm adjustment, PT G3/8 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the stroke is 210 mm, ensure adequate guidance for long unsupported loads to prevent rod side-loading damage.
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 SAIJ80BX210-30S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 210 mm nominal stroke by up to 30 mm, creating a 180-210 mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
The maximum thrust is 513 kgf at 1.0 MPa.
