About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-75
The AirTAC SAIJ63X170-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 1559N push force at 0.5MPa, with a usable travel window that can be dialed back from 170mm down to 95mm. This wide 75mm adjustment range allows operators to fine-tune the retract end-position during commissioning or product changeovers without swapping out the entire actuator.
Configured with an SUS420J2 stainless steel rod for enhanced corrosion resistance, this model uses a PT tapered G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard variants.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-75 Is Used
Product Changeover Systems
Quickly adapt machinery for different package sizes by dialing in the exact end-stop position within the 95-170mm window without changing hardware.
Machining Fixtures
Fine-tune clamping and positioning depth during initial machine setup, ensuring perfect alignment before locking down the final travel distance.
Adjustable Ejection
Control the ejection stroke length on assembly lines to safely push varying part geometries without overtraveling or damaging components.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-75 the Right Cylinder?
Choose this 63mm bore actuator when your application requires the 1559N thrust at 0.5MPa and significant on-the-fly travel modification. If your process needs less force, stepping down to a 50mm bore yields 982N push force. The 75mm adjustment window is ideal for machinery handling multiple product sizes, replacing the need to maintain an inventory of fixed-stroke SAI cylinders for every specific length.
Because the nominal stroke is 170mm, the 20mm diameter piston rod and M16x1.5 thread provide robust resistance to side-loading, though an external guide is still recommended for heavy radial loads. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air pressure. For fail-safe load holding, integrate an external rod lock or pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX170-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 170mm down to a minimum of 95mm. This provides a 75mm adjustment window for fine-tuning the retract end position at commissioning without adding external stops.
At a standard 0.5MPa operating pressure, the SAIJ63X170-75 provides 1559N of push force and 1402N of pull force. At the maximum rated pressure of 1.0MPa, it delivers up to 318kgf of thrust.
