This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X75-20, 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 SIJ32X75-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X75-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X75-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-20
The AirTAC SIJ32X75-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 75mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 55-75mm end position. The direct replacement is the SAIJ32X75-20, matching the interface, force, and adjust window.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-20 Is Used
Gripper Jaw Actuation
Tuning the extend end position by up to 20mm on-site allows precise gripper jaw alignment without machining custom spacers.
Transfer Pusher Setup
Adjusting the extend stroke from 55 to 75mm accommodates varying product sizes on a transfer line without swapping cylinders.
Light Assembly Pinning
Trimming the extend stroke accurately seats pins or light plugs, compensating for fixture tolerances directly at the machine.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X75-20 with the SAIJ32X75-20
To replace the discontinued SIJ32X75-20, order the direct replacement SAIJ32X75-20 (insert A after S), retaining the 32mm bore, 75mm nominal stroke, 20mm adjust window, G1/8 port, and ISO 15552 mounting interface. Choose the 20mm adjust window if your fixture needs field tuning of the extend end position within a 55-75mm range. Mounting options include Basic, FA, LB, and TC brackets. Because this SKU lacks the -S suffix, it has no magnet and cannot accept a sensor. For stroke lengths of 300mm or more, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X75-20
- ✓ 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 SIJ32X75-20 FAQ
Yes, the SIJ32X75-20 is discontinued. The direct replacement is the SAIJ32X75-20, which shares the same ISO 15552 interface, 32mm bore, 75mm stroke, 20mm adjust window, and G1/8 port.
The external stop screw provides a 20mm adjust window, allowing you to shorten the 75mm nominal extend stroke down to 55mm on-site.
