About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-20
The AirTAC SAIJ32X220-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 220 mm travel by up to 20 mm for a precise 200-220 mm usable window. The extruded aluminum barrel includes sensor grooves on both sides, and with a PT tapered port, it integrates seamlessly into existing pneumatic setups.
This adjustable-stroke variant uses a rear mechanical stopper to fine-tune the retract end position at commissioning without swapping cylinders or adding external stops. The 12 mm rod and M10x1.25 thread provide a robust interface for small-scale loads, while the standard variable air cushion at both ends ensures smooth deceleration across its 30-800 mm/s operating speed.

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 SAIJ32BX220-20 Is Used
Machine Changeover
Dial in the 200-220 mm travel window during product size changes without physically replacing the cylinder or repositioning external stopper blocks.
Light Diverter Setup
Adjust the stroke length on a sorting arm to handle varying package sizes on the fly, relying on the SUS304 rod for wear resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX220-20 the Right Cylinder?
The SAIJ32X220-20 is selected over a fixed SAI cylinder when a machine requires a variable end-stop to accommodate product changeovers or fine-tune a 200-220 mm travel window during setup. For a true ISO 15552 replacement, match the 32 mm bore, 220 mm stroke, PT port, and mounting choice from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (omitting FB, CA, CB, and CR).
Because the 220 mm stroke is moderately long for this bore size, ensure external guiding is used to prevent excessive side-loading on the 12 mm rod. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ32BX220-20 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm. This creates a 200-220 mm usable travel window for fine-tuning the end position at commissioning without changing the cylinder.
