This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X250-30, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 250mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X250-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30
The AirTAC SIJ32X250-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore, 250 mm nominal stroke, and a G1/8 port. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 220 to 250 mm extension. This SIJ model is discontinued; the direct replacement is the SAIJ32X250-30, matching the bore, stroke, force, and mounting interface. The stop screw sets the end position and is not a load lock.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. This non-magnet SKU lacks a -S sensor groove and cannot take a magnetic switch; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30 Is Used
Diverter Gate Actuation
Conveyor sorting stations needing field stroke tuning to set the exact gate open position for varying package widths without machining a custom cylinder.
Variable Depth Sealing
End-of-line packaging equipment where the external stop screw trims the extend stroke on-site to accommodate different carton depths quickly.
Adjustable Product Push-off
Warehouse routing lanes requiring precise push-off distances that can be dialed in by shortening the extend stroke up to 30 mm during commissioning.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30 with the SAIJ32X250-30
To replace the discontinued SIJ32X250-30, order the direct replacement SAIJ32X250-30, keeping the ISO 15552 mounting and 30 mm adjust window (usable extend 220-250 mm). Reuse FA, LB, or TC mounts. Because this SKU has no -S suffix, it cannot accept a magnetic switch. For this 250 mm stroke, verify side-load limits. The external stop sets end position but does not lock; for held loads use SAIL or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X250-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30 FAQ
Yes, the AirTAC SIJ32X250-30 is discontinued. The direct replacement is the SAIJ32X250-30, which shares the identical ISO 15552 interface, 32 mm bore, 250 mm nominal stroke, 30 mm adjust window, and G1/8 port.
The external stop screw window is 30 mm, allowing you to trim the extend stroke from 250 mm down to 220 mm on-site.
