This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X125-30, 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 SIJ32X125-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X125-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 125mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X125-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X125-30
The AirTAC SIJ32X125-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 95-125 mm forward travel out of the 125 mm nominal maximum.
Because the SIJ line is end-of-life, the direct replacement is the SAIJ32X125-30, matching the interface, bore, force, and mounting. The SAIJ upgrade introduces a two-piece Y-shaped one-way piston seal for lower start-up pressure and longer life. As this SKU lacks the -S magnet, it cannot accept a magnetic switch. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X125-30 Is Used
Adjustable End-Stop Clamping
Ideal for clamping stations where material thickness varies, letting operators dial in the exact 95-125 mm extend position via the external stop screw without re-plumbing the G1/8 air lines.
Variable-Length Ejection Pusher
Provides on-site stroke tuning for a conveyor ejection gate that must occasionally shorten its reach by up to 30 mm to accommodate different package sizes on the fly.
Tunable Diverting Arm
Useful in sortation systems where the diverting arm needs precise field adjustment of its forward travel to handle varying product dimensions safely.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X125-30 with the SAIJ32X125-30
To replace the discontinued SIJ32X125-30, order the direct replacement SAIJ32X125-30, which preserves the ISO 15552 mounting interface, 125 mm stroke, 30 mm adjust window, and G1/8 port. Choose the 30 mm adjust window if your application requires field-tuning the extend stroke between 95 and 125 mm. Mounting attachments (FA, LB, TC) can be reused directly. Because this SKU has no -S suffix, it cannot support a magnetic switch. For stroke lengths of 300 mm or more, verify your side-load limits to prevent excessive rod wear. Remember that the external stop screw merely sets the end position; it does not hold the load on air loss—use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X125-30
- ✓ 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 SIJ32X125-30 FAQ
Yes, the SIJ32X125-30 is discontinued. The direct replacement is the SAIJ32X125-30, which shares the identical ISO 15552 interface, 32 mm bore, 125 mm stroke, 30 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The external stop screw provides a 30 mm adjust window, allowing you to trim the extend stroke from the 125 mm nominal maximum down to 95 mm on-site. The stop sets end position only and is not a load lock.
