About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-50
The AirTAC SAIJ32X50-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 402N of push force at 0.5 MPa. Because the 50mm adjustment code matches the nominal stroke, you can dial the effective travel down to a zero-stop, providing a 0-50mm usable window for highly precise positioning. This flexibility eliminates the need to physically swap cylinders during product changeovers.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 32mm bore unit features PT tapered ports and a 12mm rod with an M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic sensors exactly where needed without external brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-50 Is Used
Product Changeover
Dial in the exact retract distance from 0 to 50mm during format changes without physically replacing the cylinder or adding shims.
End-Stop Tuning
Fine-tune the final resting position at machine commissioning to perfectly mate with varying part geometries.
Variable Positioning
Set multiple retract endpoints on a single axis to handle different product sizes on the same conveyor line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-50 the Right Cylinder?
Choose this 32mm bore model when an application demands 402N push force at 0.5 MPa with highly variable end-position requirements. If your setup needs less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 628N. The rear adjuster acts strictly as a mechanical stop for the retract stroke and does not lock the load; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. This SAIJ variant uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ32BX50-50 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 50mm. Since the nominal stroke is 50mm, the usable travel window is 0-50mm, allowing you to set the exact retract end-position without changing the cylinder.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
