About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-50S
The AirTAC SAIJ32X500-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 450 to 500 mm usable travel window, allowing you to dial back the nominal 500 mm stroke by up to 50 mm during commissioning. It delivers 402 N of push force at 0.5 MPa and includes a magnetic piston for position sensing.
This unit uses a SUS420J2 stainless steel rod for corrosion resistance and has PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, accepting AirTAC CMSE reed and DMSE electronic solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-50S Is Used
Machine Changeover
Dial in the exact 450 to 500 mm end-stop during product size changes without swapping cylinders.
Assembly Positioning
Fine-tune the retract distance on automated assembly lines to accommodate varying part widths.
Sensor Calibration
Use the integrated magnet with CMSE or DMSE switches to confirm the adjusted end position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-50S the Right Cylinder?
Choose this 32 mm bore cylinder when your setup requires exact end-position tuning without adding external stops. If your application needs more thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The rear adjuster on this SAIJ model acts only as a travel stop; it does not hold the load without live air pressure. For true load-holding, consider an SAIL or BSAI cylinder. Because the stroke is 500 mm, an external guide is recommended to prevent excessive side loading on the 12 mm rod.
To match this as an ISO 15552 replacement, verify the 32 mm bore, 500 mm stroke, 50 mm adjustment range, PT G1/8 port, and the -S magnet option.
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 SAIJ32AX500-50S FAQ
At a standard 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 500 mm down to 450 mm. This creates a 450 to 500 mm usable window for fine-tuning the end position at commissioning, but it functions as a stop and does not lock the load without air pressure.
