About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-50S
The AirTAC SAIJ80X210-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches.
This specific SKU provides a 160-210 mm usable travel window by allowing you to dial back the 210 mm nominal stroke by up to 50 mm. The SUS304 stainless steel rod is specified for superior corrosion resistance, while the extruded aluminum barrel maintains standard ISO 15552 mounting dimensions without relying on tie-rods.

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 SAIJ80BX210-50S Is Used
Product Changeover
Dial in the 160-210 mm travel window on packaging lines to accommodate different carton sizes without physically swapping the actuator.
End-Position Trimming
Use the 50 mm rear stopper screw to fine-tune the final retract position during machine commissioning, avoiding mechanical hard stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX210-50S the Right Cylinder?
The adjustable stroke is ideal for fine-tuning end positions during product changeovers without swapping the cylinder or adding external stops. Because the 210 mm stroke exceeds 300 mm is false here, a side-load guide is less critical, but the 25 mm rod still handles lateral forces better than smaller bores.
For a direct ISO 15552 replacement, match the 80 mm bore, 210 mm stroke, 50 mm adjustment, PT tapered port, and -S magnet. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air. For dead-load holding, select an external pilot-operated check valve or a SAIL locking cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX210-50S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the 210 mm nominal stroke by up to 50 mm, creating a 160-210 mm usable travel window. The adjuster functions as a mechanical stop and does not lock the load without continuous air pressure.
