This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X175-10, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X175-10
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X175-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X175-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X175-10
The AirTAC SIJ63X175-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 165-175 mm stroke out of the 175 mm nominal maximum.
As this SIJ model is end-of-life, the direct replacement is the SAIJ63X175-10, matching the ISO 15552 mounting interface, bore, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position but is not a load lock.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X175-10 Is Used
Press Fit Tuning
Final insertion depth needs exact field stroke tuning. The 10 mm adjust window trims the 175 mm extend stroke on-site to prevent over-travel on delicate press fits.
Divert Arm Positioning
Pneumatic divert arms requiring precise end-stop locations. The external stop screw allows operators to dial in the exact 165-175 mm extend position without reprogramming valves.
Carton Flap Folding
Folding mechanisms where carton sizes vary slightly. The adjustable stroke accommodates minor size differences on the line, ensuring consistent folding pressure.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X175-10 with the SAIJ63X175-10
To replace the discontinued SIJ63X175-10, order the direct replacement SAIJ63X175-10, reusing your existing FA, LB, or TC ISO 15552 mounts. The 10 mm adjust window is ideal for final end-position tuning without machining. This SKU lacks the -S magnet and cannot accept a sensor. For stroke lengths of 300 mm or more, verify your side-load limits to prevent rod distortion. The external stop screw only sets the end position; it does not hold loads on air loss, so use an external rod lock or check valve for suspended masses.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X175-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X175-10 FAQ
Yes, the SIJ63X175-10 is discontinued. The direct replacement is the SAIJ63X175-10. It shares the identical ISO 15552 interface, 63 mm bore, 175 mm stroke, 10 mm adjust window, G3/8 port, and mounting footprints, while adding an upgraded piston seal.
The external stop screw provides a 10 mm adjust window, allowing you to shorten the extend stroke from 175 mm down to 165 mm. The stop sets end position and is not a load lock.
