About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-75
The AirTAC SAIJ32X450-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to trim the effective travel down by up to 75 mm. This yields a usable 375-450 mm stroke window, allowing precise end-position tuning directly at commissioning without swapping out the actuator or adding external stops.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance, and utilizes PT tapered port threads. It relies on variable air cushions at both ends to decelerate the moving piston. Keep in mind that this rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure; for dead-stop holding, consider a SAIL or BSAI variant.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32BX450-75 Is Used
Machine Setup Tuning
Dial in the exact 375-450 mm end-stop during initial commissioning to perfect product placement without machining new hard stops.
Product Changeover
Quickly shorten the cylinder travel by up to 75 mm to accommodate varying package lengths on a packaging conveyor line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-75 the Right Cylinder?
An adjustable stroke is highly beneficial here over a fixed SAI cylinder because the 450 mm travel can be dialed back to 375 mm to accommodate product size changeovers on a line.
Because this 450 mm stroke exceeds 300 mm, the 12 mm diameter rod becomes a side-load risk if left unsupported—an external guide is strongly recommended to prevent premature seal wear. When specifying a replacement, verify the 450 mm stroke, 75 mm adjustment range, PT G1/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), which omits FB, CA, CB, and CR brackets.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX450-75 FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 450 mm nominal stroke by up to 75 mm, providing a usable travel window of 375-450 mm. It only sets the end position; it does not lock the load without live air pressure.
