This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X150-75, 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 SIJ100X150-75
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X150-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X150-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-75
The AirTAC SIJ100X150-75 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 75 mm on-site, giving a usable 75-150 mm window from the 150 mm nominal maximum. The 100 mm bore features a 25 mm carbon/SUS rod, M20x1.5 thread, 36 mm adjustable cushions, G1/2 port, and 30-800 mm/s speed.
The direct replacement is the SAIJ100X150-75, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop sets end position only—it is not a load lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-75 Is Used
Variable Pitch Indexing
Allows on-site extend stroke tuning up to 75 mm to alter product pitch without swapping the entire cylinder.
Adjustable Diverter Gate
Sets precise gate extension depths on the fly to accommodate varying package sizes on a single line.
Variable Format Stacking
Trims the extend stroke dynamically to handle different pallet or container heights in packaging zones.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-75 with the SAIJ100X150-75
To replace the discontinued SIJ100X150-75, order the SAIJ100X150-75 direct, which preserves the 75 mm adjust window, G1/2 port, and ISO 15552 mounting. Choose the adjust window based on your maximum required extension—this 75 mm window allows a 75-150 mm usable stroke. Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch; confirm sensing needs. For strokes >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X150-75
- ✓ 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 SIJ100X150-75 FAQ
Yes, the SIJ100X150-75 is discontinued. The direct replacement is the SAIJ100X150-75, offering the same ISO 15552 interface, 150 mm stroke, 75 mm adjust window, and G1/2 port. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The external stop screw provides a 75 mm adjust window, allowing you to shorten the extend stroke from the 150 mm nominal maximum down to 75 mm. The stop sets end position only and is not a load lock.
