About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-100S
The AirTAC SAIJ32X425-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the 425 mm nominal travel by up to 100 mm. This yields a usable end-position window of 325-425 mm, allowing precise on-machine tuning during product changeovers without physically swapping the barrel or adding external stops.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a piston magnet for position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches. It features PT tapered port threads (G1/8), dual-side sensor grooves on the extruded aluminum barrel, and variable air cushions at both ends. Note that the rear adjuster and cushions only decelerate the moving load; they do not function as a lock to hold position without live air pressure.

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 SAIJ32BX425-100S Is Used
Product Changeover Tuning
Dial in the exact end-position from 325 to 425 mm during packaging line format changes without replacing the cylinder or adding external mechanical stops.
Adjustable Material Feed
Sets variable stroke endpoints for feeding different lengths of raw material into a machine, using the rear stopper to define the precise cut-off point.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX425-100S the Right Cylinder?
Select this 32 mm bore unit when your application requires a 325-425 mm travel window and you need frequent end-position adjustments without mechanical rebuilds. Conversely, if your force requirements are lower, dropping to a smaller bore is advised. Because the 425 mm stroke is relatively long for a 12 mm rod, you must use an external guide to prevent excessive side-loading and rod deflection.
Choose this adjustable-stroke SAIJ model over a fixed-stroke SAI cylinder when commissioning fine-tuning or variable end-stops are required. For true load-holding without continuous air pressure, this cylinder is insufficient; you would need to specify a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead. To match this ISO 15552 interchangeable unit, confirm the 425 mm stroke, 100 mm adjuster, PT port, and the -S magnet option.
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 SAIJ32BX425-100S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective travel by up to 100 mm. This creates a usable stroke window of 325-425 mm, allowing you to fine-tune the end position at commissioning without swapping the cylinder. The adjuster only sets the travel end; it does not lock the load without live air pressure.
This specific model includes a piston magnet (-S) for use with AirTAC CMSE reed switches and DMSE electronic solid-state sensors, and it features a SUS304 stainless steel rod with PT tapered ports.
