This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X350-100, 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 SIJ32X350-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X350-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X350-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-100
The AirTAC SIJ32X350-100 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 100 mm on-site, yielding a usable 250-350 mm extension from the 350 mm nominal maximum. This 32 mm bore unit features a 12 mm rod, M10x1.25 rod thread, G1/8 port, and 27 mm adjustable cushions.
The direct replacement is the SAIJ32X350-100, matching the interface, force, and port. The SAIJ upgrade utilizes a two Y-shaped one-way piston seal for low start-up pressure and long life. Note: lacking a -S suffix, this SKU cannot take a magnetic switch. The stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-100 Is Used
Variable Depth Drilling
Adjusting the extend stop on-site allows a 250-350 mm stroke window to feed drills to precise depths without swapping cylinders.
Variable Position Diverter
Tuning the extend stroke by up to 100 mm lets a diverter arm accommodate changing package widths on a packaging line.
Adjustable Stroke Pusher
A pusher mechanism can be field-trimmed to push varying pallet sizes accurately without repositioning the ISO 15552 mount.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-100 with the SAIJ32X350-100
To replace the discontinued SIJ32X350-100, specify the direct replacement SAIJ32X350-100, retaining the ISO 15552 mounting dimensions and G1/8 port. The 100 mm adjust window allows field tuning the extend stroke down to 250 mm. Reuse FA, LB, or TC mounts. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For the 350 mm stroke, support side loads with external guides to prevent rod bending. The stop screw only sets the end position; it does not lock the load on air loss—use an external rod lock or pilot-operated check valve for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X350-100
- ✓ 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 SIJ32X350-100 FAQ
Yes, the SIJ32X350-100 is discontinued. The direct replacement is the SAIJ32X350-100, matching the ISO 15552 interface, 32 mm bore, 350 mm stroke, 100 mm adjust window, and G1/8 port. The SAIJ family also adds upgraded piston seals and SAIL/BSAI lock variants.
The external stop screw window is 100 mm, allowing the extend stroke to be shortened on-site from the 350 mm maximum down to 250 mm. The stop sets end position and is not a load lock.
