This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X150-20, 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 SIJ100X150-20
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X150-20 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 SAIJ100X150-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-20
The AirTAC SIJ100X150-20 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 20 mm on-site, giving a usable 130-150 mm extend window from the 150 mm nominal maximum. The direct replacement is the SAIJ100X150-20, retaining the exact mounting interface, force, and adjust window.
The SAIJ upgrade introduces an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S), so it cannot accept a magnetic switch. The stop screw sets end position only; it is not a load lock. For held loads, use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-20 Is Used
Press Fit Tuning
Allows operators to fine-tune the 130-150 mm extend position on-site for pressing bearings, accommodating material thickness variations without changing the entire cylinder.
Divertor Stroke Adjustment
Adjusts the extend end position by up to 20 mm to handle varying product sizes on a packaging line, ensuring precise diverting without repositioning the ISO 15552 mounts.
Pallet Stop Positioning
Provides a field-adjustable hard stop for pallets of different heights, allowing quick 20 mm reductions of the extend stroke to adapt to changing pallet profiles.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-20 with the SAIJ100X150-20
To replace the discontinued SIJ100X150-20, order the exact direct replacement SAIJ100X150-20, which preserves the G1/2 port, 150 mm stroke, 20 mm adjust window, and ISO 15552 mounting. Choose the 20 mm adjust window if you need field tuning of the extend end position. Reuse FA, LB, or TC mounts directly. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For stroke lengths of 300 mm or more, verify your side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X150-20
- ✓ 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 SIJ100X150-20 FAQ
Yes, the SIJ100X150-20 is discontinued. The direct replacement is the SAIJ100X150-20. It shares the same ISO 15552 interface, 100 mm bore, 150 mm stroke, 20 mm adjust window, G1/2 port, and mounting options, but adds an upgraded SAI piston seal for longer life.
The external stop screw provides a 20 mm adjust window, shortening the extend stroke from the 150 mm maximum down to 130 mm. The stop sets end position only and is not a load lock.
