This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X35-30, 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 SIJ100X35-30
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X35-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 35mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X35-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X35-30
The AirTAC SIJ100X35-30 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 30 mm on-site, giving a usable 5-35 mm stroke out of the 35 mm nominal maximum. The direct replacement is the SAIJ100X35-30, matching the interface, force, and mounting.
The SAIJ upgrade features an improved two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a -S magnet and cannot take a sensor. The adjust stop sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X35-30 Is Used
Short-Stroke Clamping
Ideal for clamping parts where the exact 5-35 mm extend position must be dialed in on-site to accommodate material thickness variations.
Transfer Diverter
Provides a short actuation push on a conveyor line, allowing the external stop to set the precise protrusion distance for sorting goods.
Press Fit Stop
Used in light assembly press operations where the extend stroke needs field tuning to ensure a component bottoms out correctly without over-travel.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X35-30 with the SAIJ100X35-30
To replace the SIJ100X35-30, order the SAIJ100X35-30 direct, reusing your existing FA, LB, or TC mounts. The 30 mm adjust window lets you fine-tune the extend end position on-site. This non-magnetic SKU cannot accept a sensor. For stroke lengths under 300 mm, side-load wear is minimal, but always verify rod alignment. The stop screw sets position only; it does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X35-30
- ✓ 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 SIJ100X35-30 FAQ
Yes, the SIJ100X35-30 is discontinued. The direct replacement is the SAIJ100X35-30, which shares the identical ISO 15552 interface, 100 mm bore, 35 mm stroke, 30 mm adjust window, G1/2 port, and mounting options.
The external stop screw provides a 30 mm adjust window, allowing the 35 mm nominal extend stroke to be shortened to a minimum of 5 mm on-site.
