About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-100
The AirTAC SAIJ63X105-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 5 to 105 mm, allowing you to dial back the 105 mm nominal stroke by up to 100 mm. This extreme adjustment range is perfect for highly variable product sizes on a single line. Delivering 1559 N of pull force at 0.5 MPa, it handles solid mid-range actuation tasks.
This variant is built with a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It supports AirTAC CMSE reed and DMSE electronic sensors, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-100 Is Used
Variable End-Stop Positioning
Dial in precise retract distances from 5 to 105 mm on the fly, perfect for accommodating multiple product lengths without changing the cylinder.
Machine Changeover Setup
Rapidly adjust the stroke end-position during product line changeovers, saving commissioning time by tuning the rear stopper instead of adding external shims.
Corrosive Environment Actuation
Leverage the SUS420J2 stainless steel rod for reliable push force in environments where moisture or mild chemicals would degrade standard carbon steel rods.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-100 the Right Cylinder?
Choose this 63 mm bore when your application requires frequent size changeovers and a wide variance in end-stops, avoiding the need to physically swap cylinders for different product runs. If your process demands less force, stepping down to the 50 mm bore yields 825 N of pull at 0.5 MPa. For heavier loads, the 80 mm bore offers 2268 N of pull at 0.5 MPa. Because the nominal stroke is 105 mm, you do not need external side-load guides.
This model is dimensionally interchangeable per ISO 15552. To match this configuration exactly when replacing a unit, specify the 63 mm bore, 105 mm stroke, 100 mm adjustment range, PT port threads, and the SUS420J2 stainless steel rod. Note that a plain SAIJ does not hold its load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ63AX105-100 FAQ
A rear external stopper screw lets you shorten the effective stroke by up to 100 mm. This gives the 105 mm nominal stroke a usable travel window of 5 to 105 mm, allowing fine-tuning of the end position without swapping the cylinder.
At 0.5 MPa operating pressure, it provides 1559 N of pull force and 1402 N of push force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 318 kgf.
