This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X200-40, 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 SIJ100X200-40
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X200-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X200-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X200-40
The AirTAC SIJ100X200-40 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 40 mm on-site, giving a usable 160-200 mm window from the 200 mm nominal maximum. This 100 mm bore uses a G1/2 port, M20x1.5 rod thread, and 36 mm adjustable cushions. The direct replacement is the SAIJ100X200-40, matching the interface, bore, force, and mounting.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X200-40 Is Used
Press Fit Tuning
Allows operators to dial in the exact 160-200 mm extend position on-site for seating bearings without remachining hard stops.
Variable Length Diverter
Adjusts the extend stroke by up to 40 mm to deflect varying package sizes on a sorting line without swapping cylinders.
Pallet Positioning Stop
Sets a precise external end-stop for pallets, trimming the stroke on-site to adapt to different pallet heights.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X200-40 with the SAIJ100X200-40
To replace this discontinued SIJ100X200-40, order the SAIJ100X200-40 direct directly. The -40 adjust window means you can shorten the extend stroke by up to 40 mm on-site; choose this specific model when your end-stop requires field tuning between 160 and 200 mm. Mounting reuse is seamless via ISO 15552 interface dimensions (Basic, FA, LB, TC). Because this SKU lacks the -S suffix, it has no magnet and cannot accept a reed switch. For stroke lengths of 300 mm or more, verify your side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X200-40
- ✓ 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 SIJ100X200-40 FAQ
Yes, the SIJ100X200-40 is discontinued. The direct replacement is the SAIJ100X200-40. It shares the identical ISO 15552 interface, 100 mm bore, 200 mm stroke, 40 mm adjust window, G1/2 port, and mounting options, but adds an upgraded piston seal.
The external stop screw window is 40 mm, allowing you to trim the extend stroke from the 200 mm maximum down to 160 mm. The stop sets position only and is not a load lock.
