This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X225-20, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X225-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20
The AirTAC SIJ80X225-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 225 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable 205-225 mm window. The direct replacement is the SAIJ80X225-20, matching the interface, force, and mounting.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant. This non-magnetic SKU cannot take a switch.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20 Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to set precise drilling depths for different material thicknesses without changing tooling.
Variable Length Diverter
Trims the extend position to deflect varying package sizes on a conveyor line, accommodating on-the-fly format changes.
Adjustable Stop Gate
Sets the physical end-stop position for pallets of differing widths, allowing flexible cell reconfiguration.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20 with the SAIJ80X225-20
To replace this discontinued SIJ80X225-20, order the direct replacement SAIJ80X225-20. The -20 mm adjust window allows field tuning the extend end position without shims. Mounting reuses ISO 15552 interfaces like FA, LB, or TC. Because this SKU lacks the -S magnet, it cannot accept a sensor; for sensing use legacy CS1-B/DS1-B on a compatible -S model. For strokes >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-20
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-20 FAQ
Yes, the SIJ80X225-20 is discontinued. The direct replacement is the SAIJ80X225-20, which shares the same ISO 15552 interface, 80 mm bore, 225 mm stroke, G3/8 port, and mounting options.
The external stop screw allows trimming the extend stroke by up to 20 mm on-site (usable 205-225 mm). Note this stop sets end position and is not a load lock.
