About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-100
The AirTAC SAIJ32X500-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 400 to 500 mm, allowing you to trim the nominal 500 mm stroke by up to 100 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet for position sensing.
This model uses a SUS304 stainless steel piston rod (option B) for enhanced corrosion resistance. The rear adjuster functions purely as a mechanical stop to fine-tune the end position without adding external stops; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 400 and 500 mm during machine setup to accommodate different material lengths without changing hardware.
Product Changeover
Quickly reconfigure the stroke limit on packaging lines when switching to a new product size, minimizing downtime between production runs.
Light-Duty Positioning
Utilize the 402 N push force at 0.5 MPa for precise, low-force clamping or positioning tasks that require exact end-point control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-100 the Right Cylinder?
Choose this 32 mm bore if your application requires the 402 N push force at 0.5 MPa. If your process needs greater thrust, stepping up to the 40 mm bore yields 628 N. The 100 mm adjustment range is ideal for machines handling varied product sizes, allowing you to reconfigure the end-of-stroke position on the fly rather than swapping out a fixed-stroke SAI cylinder. Because the nominal stroke is 500 mm, an external guide is recommended to prevent excessive side-loading on the 12 mm rod.
To match this ISO 15552 cylinder for a direct replacement, verify the 32 mm bore, 500 mm stroke, 100 mm adjustment range, PT tapered port threads, and the SUS304 rod material. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. Note that this unit lacks a magnet, so it cannot interface with 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 SAIJ32BX500-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the 500 mm nominal stroke down to 400 mm. It is a travel stop for end-position tuning, not a lock, and cannot hold a load without continuous air pressure.
