This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X80-40S, 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 SIJ32X80-40S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X80-40S 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 SAIJ32X80-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-40S
The AirTAC SIJ32X80-40S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 80 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 40-80 mm forward travel. The stop sets the end position but is not a load lock. It features a G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions. This unit includes a piston magnet (-S) for legacy CS1-B/DS1-B sensors.
As SIJ is end-of-life, the direct replacement is the SAIJ32X80-40S, retaining the same interface, force, and adjust window. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-40S Is Used
Actuator End-Stop Tuning
Ideal for small clamping fixtures where the extend stroke must be dialed in precisely on-site, using the 40 mm adjust window to accommodate material thickness variations without remounting.
Adjustable Ejection Stroke
Used in light ejection stations to vary the push distance (40-80 mm) for different product heights, allowing quick changeovers while maintaining a rigid external stop.
Variable Length Diverter
Deployed on conveyor lines where a diverter arm needs field-adjustable reach to redirect packages of varying widths, setting the exact extend position via the stop screw.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X80-40S with the SAIJ32X80-40S
To replace the discontinued SIJ32X80-40S, order the SAIJ32X80-40S for a direct swap. The 40 mm adjust window is ideal if your end-stop requires on-site tuning between 40 and 80 mm. Mounting reuses ISO 15552 attachments (FA, LB, TC). The -S suffix ensures a piston magnet for legacy CS1-B/DS1-B switches; the SAIJ uses current sensors. For stroke lengths over 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X80-40S
- ✓ 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 SIJ32X80-40S FAQ
Yes, the SIJ32X80-40S is discontinued. The direct replacement is the SAIJ32X80-40S. It shares the same ISO 15552 interface, 32 mm bore, 80 mm stroke, 40 mm adjust window, G1/8 port, and mounting options, but features an upgraded two-piece Y-shaped piston seal for longer life.
The external stop screw provides a 40 mm adjust window, allowing the 80 mm extend stroke to be shortened on-site down to 40 mm. The stop sets end position and is not a load lock.
