This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X350-100, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X350-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100
The AirTAC SIJ80X350-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 350mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100mm on-site, yielding a usable 250-350mm window. The direct replacement is the SAIJ80X350-100, matching the interface, force, and mounting.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch. 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100 Is Used
Variable Depth Drilling
Adjusting the extend stop on-site to tune drill depth precisely across multiple material thicknesses without swapping cylinders.
Adjustable Diverter Arms
Trimming the extend stroke by up to 100mm to accommodate changing package widths on a packaging line dynamically.
Variable Height Stops
Setting custom end positions for different pallet heights where the full 350mm stroke is occasionally restricted by 100mm.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100 with the SAIJ80X350-100
To replace the discontinued SIJ80X350-100, order the direct replacement SAIJ80X350-100, reusing your FA, LB, or TC ISO 15552 mounts. Choose the 100mm adjust window if your field tuning needs the full 250-350mm range. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For the 350mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X350-100
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100 FAQ
Yes, the SIJ80X350-100 is discontinued. The direct replacement is the SAIJ80X350-100, which shares the identical ISO 15552 interface, 350mm stroke, 100mm adjust window, G3/8 port, and mounting.
The external stop screw provides a 100mm adjust window (usable extend 250-350mm). The stop sets end position only and is not a load lock.
