This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X80-50, 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 SIJ32X80-50
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X80-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X80-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-50
The AirTAC SIJ32X80-50 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and G1/8 port. An external stop screw lets you trim the extend stroke by up to 50 mm on-site, giving a usable 30-80 mm stroke out of the 80 mm maximum.
The direct replacement is the SAIJ32X80-50, retaining the same interface, force, and mounting. The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note: this non-magnetic SKU lacks a -S sensor groove and cannot accept reed switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-50 Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 50 mm on-site allows precise tuning of a diverter gate endpoint without machining custom spacers.
Package Stopper Adjustment
An external stop screw lets operators dial in the 30-80 mm extended position to handle varying carton sizes on a single line.
Light Press Toning
Field adjustment of the extend stroke provides exact 402 N @0.5 MPa contact positioning for light assembly press tasks.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-50 with the SAIJ32X80-50
To replace this discontinued model, map directly to the SAIJ32X80-50. The 50 mm adjust window is ideal if the final extend position needs on-site tuning between 30 and 80 mm. Mounting interfaces include Basic, FA, LB, and TC. Because this unit lacks the -S suffix, it cannot support legacy CS1-B/DS1-B sensors. For stroke lengths >=300 mm, verify side-load constraints to prevent rod binding. The external stop sets the end position but is not a load lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X80-50
- ✓ 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 SIJ32X80-50 FAQ
Yes, the SIJ32X80-50 is discontinued. The direct replacement is the SAIJ32X80-50, which shares the identical ISO 15552 interface, 32 mm bore, 80 mm stroke, 50 mm adjust window, G1/8 port, and mounting options.
The external stop screw allows you to trim the extend stroke by up to 50 mm on-site, yielding a usable 30-80 mm stroke. The stop sets end position and is not a load lock.
