About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX45-10S
Its integrated 10mm adjustment screw creates a precise 35-45mm usable travel window, enabling exact end-position tuning at commissioning without external stops. The SUS304 stainless steel rod provides high corrosion resistance, while the pre-installed magnet supports CMSE reed and DMSE electronic sensors.
Dimensionally interchangeable per ISO 15552, this extruded aluminum profile cylinder omits FB, CA, CB, and CR mounts, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces. The PT tapered port threads ensure a tight pneumatic seal, and variable air cushions at both ends manage deceleration across its 30-800mm/s speed range.

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 SAIJ80BX45-10S Is Used
Precision End-Stop Tuning
Dial in the exact 35-45mm travel window during machine commissioning to perfect part seating without machining custom spacers.
Product Size Changeover
Quickly adjust the rear stopper by up to 10mm to accommodate varying product lengths on an automated packaging line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX45-10S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, whereas a fixed SAI cylinder lacks this commissioning flexibility. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ80X45-10-S cannot hold a load without live air. For positive load-holding, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI series.
To match this exact configuration for an ISO 15552 replacement, verify the 80mm bore, 45mm nominal stroke, 10mm adjustment range, PT port threads, SUS304 (B) rod material, and the -S magnet option.

- ✓ 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 SAIJ80BX45-10S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop that trims the effective travel, creating a 35-45mm usable stroke window from the 45mm nominal stroke. It only sets the end position and does not lock the load without continuous air pressure.
