About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-50
It features an extruded aluminum barrel with sensor grooves on both sides and a robust 25mm piston rod. By utilizing the rear adjusting screw, you can trim the 210mm nominal stroke back by up to 50mm, creating a precise 160-210mm usable travel window for exact end-position tuning.
This configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The rear stopper allows for fine-tuning during commissioning or product changeovers without swapping the entire cylinder. It operates at speeds of 30-800mm/s and uses adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ80BX210-50 Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within the 160-210mm window during machine commissioning to accommodate new tooling lengths without adding external stopper blocks.
Product Size Changeover
Quickly adjust the stroke by up to 50mm on packaging lines to handle different carton sizes, ensuring precise positioning without changing out the cylinder.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod in humid or washdown manufacturing environments to push and pull heavy jigs while preventing surface degradation.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-50 the Right Cylinder?
The 50mm adjustment range is ideal for production lines handling varying product sizes, allowing operators to dial in the exact 160-210mm stroke on the fly instead of machining external stops. For any stroke at or exceeding 300mm, an external guide is recommended to prevent excessive side-loading, though this 210mm stroke remains well within safe parameters.
When replacing an ISO 15552 cylinder, match the 80mm bore, 210mm nominal stroke, 50mm adjustment, PT G3/8 port, and your required mounting bracket. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider the SAIL or BSAI series 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 SAIJ80BX210-50 FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the 210mm nominal stroke by up to 50mm, providing a usable travel window of 160-210mm. It fine-tunes the end position but does not lock the load without continuous air pressure.
At the maximum rated pressure of 1.0 MPa, it can deliver up to 513 kgf.
