This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X60-40S, 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 SIJ63X60-40S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X60-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40S
The AirTAC SIJ63X60-40S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 60 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 20-60 mm extend window. The stop sets the end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.
The direct replacement is the SAIJ63X60-40S, reusing the same ISO 15552 mounting interface, bore, stroke, adjust window, and force. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40S Is Used
Variable Depth Spot Facing
Machining stations needing precise, on-site depth tuning can trim the extend stroke by up to 40 mm to accommodate different casting thicknesses without reprogramming the motion controller.
Adjustable Package Diverters
Sorting lines handling mixed carton widths use the 20-60 mm extend window to alter the diverter reach on the fly, ensuring gentle physical contact without crushing the packaging.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X60-40S with the SAIJ63X60-40S
To replace the discontinued SIJ63X60-40S, order the direct replacement SAIJ63X60-40S, which preserves the 63 mm bore, 60 mm nominal stroke, 40 mm adjust window, G3/8 port, and M16x1.5 rod thread. Choose the 40 mm adjust window if your process requires field-tuning the extend stroke down to 20 mm without swapping cylinders. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ replacement uses current AirTAC switches). Because the 60 mm stroke is under 300 mm, side-load rod deflection is minimal, but ensure adequate guidance for the 20 mm piston rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X60-40S
- ✓ 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 SIJ63X60-40S FAQ
Yes, the SIJ63X60-40S is discontinued. The direct replacement is the SAIJ63X60-40S. It shares the identical ISO 15552 interface, 63 mm bore, 60 mm nominal stroke, 40 mm adjust window, G3/8 port, and mounting options. The SAIJ family features an upgraded piston seal for longer life.
The external stop screw provides a 40 mm adjust window, allowing the 60 mm extend stroke to be shortened to a minimum of 20 mm on-site. The stop sets end position and is not a load lock.
