About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-10
The AirTAC SAIJ32X500-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 490-500 mm, letting you dial back the nominal 500 mm stroke by up to 10 mm during commissioning without adding external stops. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers 402 N of push force at 0.5 MPa.
This model uses an extruded aluminum barrel with sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE electronic sensors if a magnet is specified later. The rear adjuster acts purely as a travel stop to set deceleration limits and does not hold the load without live air pressure. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-10 Is Used
Machine Changeover
Dial in the 490-500 mm travel window during product size transitions to set exact end-stops without physically replacing the actuator.
Material Diverting
Fine-tune the diverting arm position on a packaging line by adjusting the rear stopper to compensate for varying package lengths.
Assembly Positioning
Use the 10 mm adjustment range to precisely set the retract distance for an assembly tool head, ensuring accurate part contact.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-10 the Right Cylinder?
Choose this 32 mm bore actuator when an application requires precise end-position tuning at machine setup or during product changeover, avoiding the need to physically swap cylinders. If your process needs higher clamping power, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. For exact ISO 15552 interchangeability, match the 500 mm stroke, 10 mm adjustment range, PT port thread, and the specified mounting hardware.
Because the 500 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread still require an external guide to prevent excessive side-loading and binding. Remember that the rear adjuster is a stop, not a locking device; if you need true load-holding without live air pressure, consider the SAIL or BSAI series instead.
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 SAIJ32BX500-10 FAQ
The rear adjuster allows you to shorten the effective travel from the 500 mm nominal stroke by up to 10 mm, creating a 490-500 mm usable window. It functions as an external stop for end-position tuning and does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, this 32 mm bore double-acting cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
