About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-30
The AirTAC SAIJ32X500-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 470-500 mm usable travel window, allowing you to dial back the nominal 500 mm stroke by up to 30 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. Because the stroke is 500 mm on a 12 mm rod, external guiding is recommended to manage side loads.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-30 Is Used
End-Position Tuning
Dial in the exact 470-500 mm retract distance during machine setup to perfect product placement without swapping cylinders.
Product Changeovers
Quickly adjust the stroke by up to 30 mm to accommodate different material lengths on a packaging line.
Extended Travel Diverter
Use the 500 mm stroke to push items across a wide belt, relying on the adjuster to prevent overtravel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-30 the Right Cylinder?
Choose this 32 mm bore if your application requires 402 N push force at 0.5 MPa; stepping up to a 40 mm bore would provide 628 N, while dropping to a smaller bore sacrifices thrust. The adjustable 470-500 mm travel window is ideal for product changeovers or fine-tuning end positions without adding external stops.
When specifying a replacement, match the 500 mm stroke, 30 mm adjustment range, PT port, and SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-end holding, consider an external rod lock or the SAIL series.
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 SAIJ32BX500-30 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 500 mm down to 470 mm. It allows fine-tuning the end position at commissioning without adding external stops, though it does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ32X500-30 provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
