This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X125-20, 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 SIJ32X125-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X125-20 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 SAIJ32X125-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X125-20
The AirTAC SIJ32X125-20 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 20mm on-site, giving a usable 105-125mm range from the 125mm nominal maximum.
The direct replacement is the SAIJ32X125-20, matching the interface, force, and adjust window. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position without locking the load on air loss.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X125-20 Is Used
Diverter Gate Positioning
Fine-tunes the extend stroke by up to 20mm on-site to set the exact contact point of a package diverter gate without swapping cylinders.
Light Transfer Stops
Adjusts the extend end-position on the fly to accommodate varying product lengths on a 32mm bore conveyor stopping mechanism.
Clamp Force Calibration
Dials in the precise 105-125mm extend reach to control clamping depth on delicate sub-assemblies, preventing over-travel.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X125-20 with the SAIJ32X125-20
Replace the discontinued SIJ32X125-20 directly with the SAIJ32X125-20. The 20mm adjust window is ideal for precise end-position tuning without machining. Mounting reuses ISO 15552 interfaces like FA, LB, or TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch; add -S for legacy CS1-B/DS1-B sensor accuracy. For stroke lengths of 300mm or more, verify your side-load limits. The stop screw is not a lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X125-20
- ✓ 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 SIJ32X125-20 FAQ
Yes, the SIJ32X125-20 is discontinued. The direct replacement is the SAIJ32X125-20, which shares the same ISO 15552 interface, 32mm bore, 125mm stroke, 20mm adjust window, G1/8 port, and mounting options. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for longer life.
The external stop screw provides a 20mm adjustment window, allowing the extend stroke to be shortened from the 125mm maximum down to 105mm. The stop sets end position but is not a load lock.
