This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X800-75, 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 SIJ100X800-75
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X800-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75
The AirTAC SIJ100X800-75 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 800 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 725-800 mm window. This SIJ model is discontinued; the direct replacement is the SAIJ100X800-75, matching the ISO 15552 interface, bore, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet, so it cannot accept a reed switch. The stop screw sets end position but is not a load lock; for held loads use SAIL or an external rod lock.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75 Is Used
Variable Press Stroke
Trimming the extend stroke by up to 75 mm on-site allows precise end-position tuning for a press without machining custom spacers.
Adjustable Diverter Arm
Field-tuning the 725-800 mm extend window lets operators alter the divert point on a conveyor layout without changing the cylinder.
Variable Height Pallet Stop
An external stop screw provides repeatable end positions for differing pallet heights, avoiding the need for multiple fixed-stroke units.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X800-75 with the SAIJ100X800-75
To replace the discontinued SIJ100X800-75, order the direct replacement SAIJ100X800-75, reusing your existing FA, LB, or TC mounts. The 75 mm adjust window is ideal if your final extend position needs on-site tuning between 725 and 800 mm. Because the 800 mm stroke is long, verify side-load limits and use external guides to prevent rod bending. This non-magnetic SKU cannot take legacy CS1-B/DS1-B sensors; for position feedback you must upgrade to a -S model.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X800-75
- ✓ 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 SIJ100X800-75 FAQ
Yes, the SIJ100X800-75 is discontinued. The direct replacement is the SAIJ100X800-75, which shares the same ISO 15552 interface, 100 mm bore, 800 mm stroke, 75 mm adjust window, G1/2 port, and mounting.
The external stop screw window is 75 mm, allowing you to trim the extend stroke from 800 mm down to 725 mm. The stop sets end position and is not a load lock.
