About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-100
The AirTAC SAIJ63X110-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the travel by up to 100 mm. This yields a highly flexible usable stroke window of 10 to 110 mm, letting you dial in the exact end position during commissioning without swapping out the unit. It delivers a robust 1402 N pull force at 0.5 MPa, making it suitable for medium-duty handling tasks.
This specific configuration uses a SUS420J2 stainless steel rod for enhanced durability against moisture and PT tapered port threads for a tight pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily add CMSE reed or DMSE electronic sensors if position feedback is needed later. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-100 Is Used
Machine Changeover
Quickly fine-tune the 10 to 110 mm travel window during product size changeovers without bolting on external stopper blocks.
End-Position Tuning
Dial in the exact retract end-position at commissioning to compensate for mechanical tolerance stack-up in the fixture.
Variable End Stops
Ideal for assembly lines where the same actuator must handle multiple part lengths by simply adjusting the rear screw.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX110-100 the Right Cylinder?
Choose this 63 mm bore cylinder when your application requires 1559 N of push force at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N. An adjustable stroke is highly beneficial when you need variable end-stops for product changeovers, whereas a fixed-stroke SAI cylinder is sufficient for repetitive single-depth operations. Because the nominal stroke is 110 mm, no external side-load guide is strictly required, but the 20 mm rod and M16x1.5 thread provide solid resistance to minor deflection.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 110 mm nominal stroke, up to 100 mm adjustment range, PT G3/8 port, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that SAIJ omits the FB, CA, CB, and CR mounts. If your process requires the load to be held mechanically without continuous air pressure, this cylinder will not suffice; consider an AirTAC SAIL or BSAI series instead.

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 SAIJ63AX110-100 FAQ
The rear adjuster screw acts as a mechanical stop that can shorten the effective travel by up to 100 mm. This gives the 110 mm nominal stroke a usable window of 10 to 110 mm, allowing precise end-position tuning without changing the cylinder.
At a 0.5 MPa operating pressure, the SAIJ63X110-100 provides 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 318 kgf.
