This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X1000-20S, 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 SIJ32X1000-20S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X1000-20S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 1000mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X1000-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X1000-20S
The AirTAC SIJ32X1000-20S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder. A 1000 mm nominal extend stroke is shortened on-site by up to 20 mm via an external stop screw, yielding a usable 980-1000 mm window. The 32 mm bore uses a G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions. This SIJ model is DISCONTINUED; the direct replacement is the SAIJ32X1000-20S, matching the ISO 15552 mounting interface, bore, and force.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X1000-20S Is Used
End-Position Trimming on Long Pushers
Dial in the exact 980-1000 mm extend reach on a 1000 mm stroke pusher without disassembling the line to add shims.
Adjustable Transfer Stop Fences
Set the precise stop fence location for varying product lengths, using the 20 mm on-site stroke adjustment.
Long-Reach Packer Positioning
Fine-tune the extended packer blade end point in a 32 mm bore actuator to accommodate carton size variations.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X1000-20S with the SAIJ32X1000-20S
To replace the discontinued SIJ32X1000-20S, order the direct replacement SAIJ32X1000-20S, which preserves the G1/8 port, M10x1.25 rod, and ISO 15552 mounting. The 20 mm adjust window is ideal for fine-tuning the extend endpoint without machining. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches. Because the stroke is 1000 mm, account for side-load and rod-bending by using external guides to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X1000-20S
- ✓ 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 SIJ32X1000-20S FAQ
Yes, the SIJ32X1000-20S is discontinued. The direct replacement is the SAIJ32X1000-20S, offering the same ISO 15552 interface, 32 mm bore, 1000 mm stroke, 20 mm adjust window, and G1/8 port.
The external stop screw provides a 20 mm adjustment window, shortening the extend stroke from 1000 mm down to 980 mm.
