About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-50
The AirTAC SAIJ32X425-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by up to 50 mm. This yields a usable stroke window of 375-425 mm, ideal for dialing in exact end positions during commissioning without adding external stops.
This specific configuration features a SUS304 stainless steel piston rod (code B) for superior corrosion resistance, making it well-suited for environments where standard carbon steel rods might degrade. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches, though this SKU is supplied without a magnet.

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 SAIJ32BX425-50 Is Used
Machine Changeover
Quickly dial in the 375-425 mm travel window to accommodate new product lengths on a packaging line without physically swapping the cylinder.
Variable End Stops
Provides an adjustable physical stop for diverting or positioning items of varying dimensions on a material handling conveyor.
Commissioning Fine-Tune
Allows engineers to precisely set the retracted end position during machine setup, avoiding the need to machine custom external spacers.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-50 the Right Cylinder?
Choose this 32 mm bore adjustable model when an application requires precise end-position tuning on the fly, such as accommodating varying product sizes on a conveyor. If your process needs more push force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Because the 425 mm stroke is relatively long for the 12 mm rod diameter, an external guide rail is highly recommended to prevent excessive side-loading and premature wear.
The rear adjuster acts solely as a travel stop to set the deceleration point alongside the standard air cushions; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series. To match this exact unit, specify: 32 mm bore, 425 mm nominal stroke, 50 mm adjustment, PT G1/8 port, Basic/LB/TC mountings, and no magnet.
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 Adjustable Cylinder SAIJ32 SAIJ32BX425-50 FAQ
The rear adjuster allows you to shorten the effective stroke by up to 50 mm, creating a usable travel window of 375 to 425 mm. This lets you fine-tune the end position at commissioning without changing the cylinder.
At the maximum operating pressure of 1.0 MPa, it can deliver up to 82 kgf.
