Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100
The AirTAC SAIJ32X150-100 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 402N push force at 0.5 MPa. Its 150mm nominal stroke pairs with a 100mm adjustment screw, creating a wide 50-150mm usable travel window for exact end-position tuning. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet.
This variant features a SUS304 stainless steel rod for corrosion resistance and a PT tapered port. The rear adjuster acts purely as a mechanical stop to trim the retract distance during commissioning; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100 Is Used
Product Changeover
Dial in the exact retract distance from 50 to 150mm when switching line formats, avoiding the need to physically swap cylinders or re-machine fixed stop blocks.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to clear mechanical interference, using the 100mm adjustment window to perfect the timing.
Variable End Stops
Adjust the effective travel on the fly for testing different sensor trigger points or part sizes without disassembling the ISO 15552 mounting interface.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100 the Right Cylinder?
Choose this 32mm bore when an application requires precise variable end-stops without adding external stops or swapping cylinders during product changeover. If your process needs higher force, stepping up to the 40mm bore yields 628N push force at 0.5 MPa. The 12mm rod and M10x1.25 thread handle moderate side loads, but because this is a 150mm stroke, external guidance is recommended for heavy offset loads.
This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. Configuration details: PT port, SUS304 rod, no magnet, 30-800mm/s speed range, and adjustable stroke up to 100mm.
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 SAIJ32BX150-100 FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 100mm. This creates a usable travel window of 50-150mm, allowing you to fine-tune the end position at commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, the 32mm bore provides 402N of push force and 345N of pull force. It can reach up to 724N push force at 0.9 MPa.
