About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-100
The AirTAC SAIJ63X1000-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down from a 1000 mm nominal stroke to a 900 mm minimum. This creates a 900-1000 mm usable window, providing exact end-position control during commissioning without swapping hardware. It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa.
This configuration features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Because the stroke reaches 1000 mm, the 20 mm rod diameter requires external guidance to prevent excessive side-loading on the piston.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-100 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point within the 900-1000 mm window during setup, allowing precise positioning of long-stroke actuators without adding external stopper blocks.
Product Size Changeover
Quickly adapt machinery to handle different product lengths by adjusting the rear screw up to 100 mm, minimizing downtime between production runs.
Long-Stroke Machine Setup
Achieve fine end-position tuning on a 1000 mm stroke actuator at commissioning, ensuring perfect alignment with external guides to manage side-load.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX1000-100 the Right Cylinder?
Choose this 63 mm bore when an application requires moderate thrust—delivering 1559 N at 0.5 MPa—and a variable end-stop. If you need significantly more force, stepping up to the 80 mm bore yields 2513 N at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, functioning as a mechanical stop rather than a lock. For applications requiring the cylinder to hold its position without live air pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 63 mm bore, 1000 mm stroke, 100 mm adjustment range, PT G3/8 port, and standard mounting options. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. As this unit lacks the -S magnet option, it does not support CMSE or DMSE electronic or reed sensors.

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 SAIJ63AX1000-100 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 318 kgf.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 1000 mm stroke model, you can reduce the stroke by up to 100 mm, creating a usable travel window between 900 mm and 1000 mm. Note that this adjuster is a stop, not a lock, and cannot hold the load without continuous air pressure.
