This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X500-100S, 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 SIJ63X500-100S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X500-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X500-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X500-100S
The AirTAC SIJ63X500-100S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 500 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 400-500 mm extension window. The stop sets the end position but is not a load lock. This SIJ model is discontinued; the direct replacement is the SAIJ63X500-100S.
The SAIJ successor retains the identical ISO 15552 mounting interface, bore, stroke, and force, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Because the 500 mm stroke invites rod bending, use external guides to manage side loads. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X500-100S Is Used
Variable Depth Forming Press
Uses the 100 mm stop screw to tune the extend stroke between 400 and 500 mm on-site, accommodating different material thicknesses without reprogramming the motion controller.
Multi-Position Pallet Stop
Sets a physical end position for pallets entering a cell, adjusting the stop distance by up to 100 mm to handle different pallet footprints while using ISO 15552 TC mounts.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X500-100S with the SAIJ63X500-100S
To replace the discontinued SIJ63X500-100S, order the direct replacement SAIJ63X500-100S, reusing your existing ISO 15552 FA, LB, or TC mounts without machining changes. Select the 100 mm adjust window if you need to trim the 500 mm nominal extend down to 400 mm on-site. The -S magnet supports legacy CS1-B/DS1-B sensors. For the 500 mm stroke, always support the load with external guides to prevent rod bending and premature seal wear. Remember that the external stop screw sets the end position but does not lock the load; for held loads without live air, specify an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X500-100S
- ✓ 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 SIJ63X500-100S FAQ
Yes, the SIJ63X500-100S is discontinued. The direct replacement is the SAIJ63X500-100S. It shares the same ISO 15552 interface, 63 mm bore, 500 mm stroke, 100 mm adjust window, G3/8 port, and mounting options. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for longer life.
The external stop screw allows you to shorten the 500 mm nominal extend stroke by up to 100 mm on-site (usable range 400-500 mm). The stop sets end position and is not a load lock.
