This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X160-30, 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 SIJ125 Double Rod Adjustable Cylinder SIJ125X160-30
The AirTAC SIJ125 Double Rod Adjustable Cylinder SIJ125X160-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X160-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-30
The AirTAC SIJ125X160-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. The external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 130-160mm range. The direct replacement is the SAIJ125X160-30, matching the G1/2 port, 32mm rod, and 40mm cushion.
The SAIJ successor retains the ISO 15552 mounting interface and adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure. The stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Where the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-30 Is Used
Press Fit Tuning
Allows field stroke tuning to dial in exact press fits without swapping cylinders.
Variable Stop Positioning
Adjusts the extend end position on-site to handle changing package sizes.
End-of-Line Diverter
Fine-tunes the extend stroke by up to 30mm to align with varying pallet heights.
Replacing the Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-30 with the SAIJ125X160-30
To replace the discontinued SIJ125X160-30, order the direct replacement SAIJ125X160-30, keeping the 160mm nominal stroke and 30mm adjust window (130-160mm usable extend). Mounting reuses ISO 15552 interfaces like FA, LB, or TC. This SKU lacks the -S magnet, so it cannot take a magnetic switch. For strokes >=300mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ125X160-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ125 Double Rod Adjustable Cylinder SIJ125X160-30 FAQ
Yes, the SIJ125X160-30 is discontinued. The direct replacement is the SAIJ125X160-30, offering the same ISO 15552 interface, 125mm bore, 160mm stroke, 30mm adjust window, and G1/2 port.
The external stop screw provides a 30mm adjust window (usable extend 130-160mm). The stop sets end position and is not a load lock.
