About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-40S
The AirTAC SAIJ50X600-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 560 to 600 mm. It delivers 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, making it well-suited for moderate-load positioning tasks. The integrated -S magnet enables position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-40S Is Used
Product Changeover
Dial in the exact retract distance within the 560-600 mm window when switching machinery between different product lengths.
Machine Setup
Fine-tune the end-of-stroke position during commissioning without fabricating custom external mechanical stops.
Variable End Stops
Adjust the travel end-point on the fly for packaging lines handling varying box dimensions.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX600-40S the Right Cylinder?
Choose this 50 mm bore when your application requires the 982 N output at 0.5 MPa, stepping up from a 40 mm bore that provides 628 N. The 40 mm adjustment range is ideal for fine-tuning the retract end-position during commissioning or product changeovers without swapping the cylinder or adding external stops. Because the nominal 600 mm stroke is substantial, an external guide is recommended to manage side-load forces on the extended rod.
For ISO 15552 interchangeability, match the 50 mm bore, 600 mm stroke, 40 mm adjustment, PT ports, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for secure load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ50 Adjustable Cylinder SAIJ50AX600-40S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 560 to 600 mm. It acts as a mechanical stop to fine-tune the end position without changing the cylinder itself.
At 0.5 MPa operating pressure, it provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
