This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X300-100, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X300-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X300-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X300-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-100
The AirTAC SIJ32X300-100 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 200-300 mm window from the 300 mm nominal maximum. The direct replacement is the SAIJ32X300-100, matching the interface, force, and mounting.
The stop screw sets the end position but is not a load lock; the piston drifts on air loss. For held loads, use an external rod lock or the SAIL/BSAI variants. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. This non-magnet SKU cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-100 Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 100 mm on-site allows a drill head to hit varied material thicknesses without re-mounting the ISO 15552 cylinder.
Adjustable Transfer Pusher
A 200-300 mm stroke window lets operators change the pusher end position on the line for different package sizes using the external stop screw.
Variable Height Diverter
Field-tuning the extend stroke lets a sorting diverter reach multiple conveyor lanes precisely, avoiding the need for fixed stop collars.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-100 with the SAIJ32X300-100
To replace the discontinued SIJ32X300-100, use the direct replacement SAIJ32X300-100, retaining the ISO 15552 mounting interface and G1/8 port. The 100 mm adjust window allows field tuning the extend stroke down to 200 mm. Reuse FA, LB, or TC mounts. As this non-magnet SKU lacks a -S sensor, it cannot take a switch. Because the 300 mm stroke invites rod bending, use external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X300-100
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-100 FAQ
Yes, the SIJ32X300-100 is discontinued. The direct replacement is the SAIJ32X300-100, matching the 32 mm bore, 300 mm stroke, 100 mm adjust window, G1/8 port, and ISO 15552 mounting.
The external stop screw shortens the extend stroke by up to 100 mm on-site (usable 200-300 mm). The stop sets end position and is not a load lock.
