Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-50
The AirTAC Adjustable Cylinder SAIJ32 SAIJ32BX55-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 55mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-50
The AirTAC SAIJ32X55-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. Its 55 mm nominal stroke can be dialed back by up to 50 mm, providing a wide 5 to 55 mm usable travel window for precise end-position tuning during commissioning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when product sizes change. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts strictly as a mechanical stop for deceleration, not a lock. For applications requiring position holding without live air pressure, consider the SAIL or BSAI series instead.

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 SAIJ32BX55-50 Is Used
Machine Changeover
Dial in the exact retract distance from 5 to 55 mm instantly when switching product sizes on a packaging line.
End-Stop Calibration
Fine-tune the final end position during machine commissioning without physically swapping the cylinder.
Variable Positioning
Set multiple retract positions on the fly for assembly machines requiring flexible stroke lengths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-50 the Right Cylinder?
If your application requires higher force, stepping up to the 40 mm bore increases output to 628 N. Conversely, if you need less force, the smaller bore options offer a lighter footprint. The 12 mm rod and M10x1.25 thread handle moderate side loads, but always guide the load externally for smooth operation.
This SAIJ configuration includes a SUS304 stainless steel rod and a PT tapered port. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552. Because it lacks a magnet, it does not support CMSE or DMSE sensors without modification.
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 SAIJ32BX55-50 FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to trim the 55 mm nominal stroke back by up to 50 mm, creating a usable travel window of 5 to 55 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air.
