About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-10
The AirTAC SAIJ63X195-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the retract end position. With a 195 mm nominal stroke and a 10 mm adjustment range, it yields a usable travel window of 185 to 195 mm. This bore size delivers a robust 1559 N push force at 0.5 MPa and 2182 N at 0.7 MPa, making it well-suited for moderate to heavy actuation tasks.
This configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It is important to note that the rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure; for true load-holding without supply pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-10 Is Used
Machine Changeover
Dial in the exact retract position within the 185-195 mm window during product size changes on a packaging line, eliminating the need to physically swap cylinders.
End-Stop Calibration
Fine-tune the final resting position of a tooling plate at commissioning, using the rear adjuster to compensate for mechanical tolerances without adding external stops.
Assembly Positioning
Set precise variable end-stops for an assembly fixture, allowing operators to quickly adjust the travel distance for different workpiece heights.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX195-10 the Right Cylinder?
Choose this 63 mm bore adjustable-stroke cylinder when your machine setup requires precise end-position calibration or frequent product changeovers without swapping hardware. If your application demands less force, stepping down to a 50 mm bore provides 982 N of push force at 0.5 MPa, while moving up to an 80 mm bore yields 2513 N. The SAIJ series supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. To achieve a true ISO 15552 replacement match, verify the 195 mm stroke, 10 mm adjustment, PT port type, and SUS420J2 rod material. Because this is a 195 mm stroke, ensure external guiding for any heavy or off-center loads to prevent excessive rod side-loading.

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 SAIJ63AX195-10 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to trim the effective stroke back by up to 10 mm from the 195 mm nominal length. This creates a usable travel window of 185 to 195 mm for precise end-position tuning during commissioning.
At a standard 0.5 MPa operating pressure, this cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
