About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-10
The AirTAC SAIJ80X210-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 200-210 mm usable travel window, allowing you to dial back the nominal 210 mm stroke by up to 10 mm during commissioning.
This unit features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for position sensing. The rear adjuster acts strictly as a travel stop to decelerate the load, not as a lock, meaning it cannot hold a 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 SAIJ80BX210-10 Is Used
End-Position Tuning
Dial in the exact 200-210 mm travel distance during machine commissioning to accommodate minor mechanical variances without disassembling the line.
Product Changeover
Quickly adjust the retract stop by up to 10 mm when switching to a slightly different product size on a conveyor or packaging setup.
Clamp Force Setup
Fine-tune the approach distance on a 2513 N clamping station to ensure consistent pressure without over-stroking the mechanism.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-10 the Right Cylinder?
Choose this 80 mm adjustable model when you need precise end-position tuning at machine setup or during product changeover without swapping cylinders or adding external stops. For higher force demands, the 100 mm bore provides 3927 N at the same pressure.
Because this cylinder has a 210 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide robust resistance to side loads, though an external guide is still recommended for optimal longevity. To replace an ISO 15552 cylinder, match the 80 mm bore, 210 mm stroke, 10 mm adjustment, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). For load-holding without live pressure, 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 SAIJ80BX210-10 FAQ
At its maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf.
The rear adjuster acts as an external stop that lets you shorten the effective stroke by up to 10 mm, giving a usable travel window of 200 to 210 mm. It only sets the travel end and does not lock the load without live air.
