This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X100-40, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 100mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X100-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40
The AirTAC SIJ100X100-40 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 60-100 mm extend out of the 100 mm nominal maximum.
The direct replacement is the SAIJ100X100-40, matching the bore, stroke, adjust window, port, and mounting interface. 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 sets position only—it is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40 Is Used
Press Fit Tuning
Allows operators to dial in the exact 60-100 mm extend position for inserting bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke on-site to deflect different package sizes on a line without swapping the cylinder.
Calibrated Forming Stop
Provides a field-tunable end position for light metal forming where the bottom dead center varies by batch.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40 with the SAIJ100X100-40
To replace the discontinued SIJ100X100-40, order the direct replacement SAIJ100X100-40, reusing your existing FA, LB, or TC ISO 15552 mounts. Choose the 40 mm adjust window if your extend endpoint requires field tuning between 60 and 100 mm. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch; for sensing, select an SAIJ-S model. For any stroke at or above 300 mm, verify your side-load limits to prevent guide failure. Finally, the external stop screw only sets the end position; it is not a lock, so for held loads use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X100-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X100-40 FAQ
Yes, the SIJ100X100-40 is discontinued. The direct replacement is the SAIJ100X100-40, offering the same ISO 15552 interface, 100 mm bore, 100 mm stroke, 40 mm adjust window, and G1/2 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 40 mm adjust window, shortening the 100 mm nominal extend stroke down to 60 mm on-site. The stop sets end position only and does not hold the load on air loss.
