About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-30S
The AirTAC SAIJ32X500-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster. It provides a usable travel window of 470-500 mm, allowing you to dial back the 500 mm nominal stroke by up to 30 mm during commissioning. In the 32 mm bore class, it delivers 563 N of push force at 0.7 MPa.
This variant features a SUS420J2 stainless steel rod and a built-in magnet for position sensing with CMSE reed or DMSE electronic switches. The PT tapered ports and extruded aluminum barrel maintain standard ISO 15552 mounting dimensions, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-30S Is Used
Machine Setup Tuning
Dial in the exact 470-500 mm end position during initial commissioning without machining custom spacers.
Product Changeover
Quickly adjust the retract stop to accommodate slight length variations when switching product runs on a line.
Variable End Stops
Use the 30 mm adjustment range to fine-tune the final resting position of a lightweight assembly mechanism.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-30S the Right Cylinder?
Choose this adjustable-stroke model when you need precise end-position tuning without swapping cylinders or adding external stops. If your application requires less force, stepping down is not an option in this series, but if you need more thrust, the 40 mm bore offers 879 N at 0.7 MPa. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is a stop, not a lock.
Because the 500 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread need external guidance to prevent side-loading damage. This model uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ32AX500-30S FAQ
At 0.7 MPa, this 32 mm bore cylinder provides 563 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster lets you shorten the effective travel from 500 mm down to 470 mm. It functions as a mechanical stop to fine-tune the end position, but it does not lock the load without live air.
