This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X80-30S, 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 SIJ32X80-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X80-30S 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 SAIJ32X80-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-30S
The AirTAC SIJ32X80-30S 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 30 mm on-site, yielding a usable 50-80 mm stroke from the 80 mm nominal maximum. It features a 32 mm bore, G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions. The direct replacement is the SAIJ32X80-30S, matching the interface, force, and mounting.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches; note the stop sets end position but is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-30S Is Used
Actuator Pinpointing
Dialing in exact extend endpoints on small clamping fixtures where a fixed 80 mm stroke would over-travel and crush delicate components.
Transfer Stroke Tuning
Adjusting the pusher extension on a modular conveyor line to accommodate varying package widths without swapping the cylinder.
Prototype Positioning
Prototyping automated stations where the exact extend distance must be empirically determined and locked via the external stop screw.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-30S with the SAIJ32X80-30S
To replace the discontinued SIJ32X80-30S, specify the SAIJ32X80-30S (insert A after the leading S), retaining the 32 mm bore, 80 mm nominal stroke, 30 mm adjust window, and G1/8 port. Choose the adjust window based on your on-site tuning needs: the -30 window allows a usable extend stroke of 50-80 mm. Mounting options include Basic, FA, LB, and TC. The -S magnet enables position sensing. For strokes >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X80-30S
- ✓ 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 SIJ32X80-30S FAQ
Yes, the SIJ32X80-30S is discontinued. The direct replacement is the SAIJ32X80-30S. It shares the same ISO 15552 interface, 32 mm bore, 80 mm stroke, 30 mm adjust window, G1/8 port, and mounting options, but features an upgraded piston seal.
The external stop screw provides a 30 mm adjust window, allowing you to trim the 80 mm nominal extend stroke down to 50 mm on-site. The stop sets end position and is not a load lock.
