Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10
The AirTAC Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 600mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10
The AirTAC SAIJ40X600-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a usable 590-600 mm stroke window, enabling precise end-position tuning at commissioning without swapping out the entire actuator. Driven by filtered air over a 30-800 mm/s speed range, it supplies 628N of push force and 528N of pull force at 0.5 MPa.
This long-travel unit is built with a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads (G1/4). The extruded aluminum barrel includes sensor grooves on both sides for mounting reed or solid-state switches. While the rear adjuster acts as a travel stop to fine-tune the end position, it does not hold the load dynamically; for position holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10 Is Used
Machine Changeover
Dial in the 590-600 mm travel window during product size changes to set new end positions quickly without physically replacing the cylinder.
Extended Transfer Lines
Pushes packages along long conveyors using the 600 mm stroke, with the rear stopper fine-tuning the exact release point.
Long-Stroke Assembly
Drives tooling carriages over extended distances, using the SUS304 rod to resist corrosion in demanding manufacturing environments.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-10 the Right Cylinder?
Choose this 40 mm bore when an application requires 628N of push force at 0.5 MPa, stepping up from a 32 mm bore (402N push) for heavier pushing tasks, or down from a 63 mm bore (1559N push) to save space and air consumption. The 10 mm adjustable stroke is ideal for machine setup and product changeover, allowing operators to dial in the exact end-stop without adding external physical stops. As an ISO 15552 interchangeable cylinder, it matches the standard SAI footprint with Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting options, omitting the FB, CA, CB, and CR styles.
Because the 600 mm stroke is quite long, the 16 mm rod and M12x1.25 thread will still experience leverage forces under side loading. An external guide is strongly recommended to prevent premature wear on the seals and barrel over this extended travel distance.
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 SAIJ40 Adjustable Cylinder SAIJ40BX600-10 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628N of push force and 528N of pull force. It can deliver up to 1130N of push force at 0.9 MPa.
The rear adjuster screw acts as an external stop that lets you shorten the nominal 600 mm stroke by up to 10 mm, providing a usable 590-600 mm travel window. It sets the end position but does not lock or hold the load without live air pressure.
