About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-10
The AirTAC SAIJ80X145-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 145 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 135-145 mm usable travel window.
This variant utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of AirTAC CMSE reed or DMSE electronic switches if a magnet is added later.

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 SAIJ80BX145-10 Is Used
Machine Setup & Changeover
Fine-tune the 135-145 mm retraction end-point rapidly when switching between product batches, avoiding the need to physically swap out the entire cylinder.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in humid or mildly corrosive manufacturing environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-10 the Right Cylinder?
The 10 mm adjustment range is ideal for dialing in exact end positions during machine commissioning or product changeovers without adding external stops. For fixed travel without this adjuster, the standard SAI series is sufficient.
Since the 145 mm stroke is below the 300 mm threshold, side-load stress is moderate, but the robust 25 mm rod and M20x1.5 thread help manage minor deflection. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for pneumatic locking, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX145-10 FAQ
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 145 mm nominal stroke by up to 10 mm. This provides a usable travel window of 135-145 mm for fine-tuning the end position at commissioning.
