This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X100-75TC, 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 SIJ32X100-75TC
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X100-75TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X100-75TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-75TC
The AirTAC SIJ32X100-75TC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a TC mount. An external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable 25-100mm extension out of the 100mm nominal maximum.
The direct replacement is the SAIJ32X100-75TC, matching the interface, bore, stroke, force, and TC mounting. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. As a non-magnet SKU, this cylinder cannot take a reed switch. The stop screw sets the end position but is not a load lock; for held loads use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-75TC Is Used
Variable Pitch Pushing
Feeding different length parts on a single line by dialing the extend stroke from 25mm to 100mm on-site without changing the cylinder.
Adjustable Sorting Diverter
Diverting packages of varying widths where the actuator end position must be fine-tuned quickly to avoid crushing the goods.
Prototype Stroke Setup
R&D tooling requiring precise physical end-position tuning during machine commissioning before finalizing fixed-stroke dimensions.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-75TC with the SAIJ32X100-75TC
To replace the discontinued SIJ32X100-75TC, specify the SAIJ32X100-75TC for an direct match retaining the TC mount and G1/8 port. The 75mm adjust window is ideal if your end-stop position varies between 25mm and 100mm. Choose FA, LB, or TC mounting accessories per ISO 15552 interface standards. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch; add -S if you need sensing. For strokes at or above 300mm, carefully manage side loads to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X100-75TC
- ✓ 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 SIJ32X100-75TC FAQ
Yes, the SIJ32X100-75TC is discontinued. The direct replacement is the SAIJ32X100-75TC. It matches the ISO 15552 interface, 32mm bore, 100mm nominal stroke, 75mm adjust window, TC mounting, and G1/8 port. The SAIJ family also features an upgraded two-piece Y-shaped piston seal for longer life.
This double-acting double-rod cylinder has a 75mm adjust window, allowing the extend stroke to be shortened from the 100mm maximum down to 25mm. The external stop sets end position but is not a load lock.
