This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X200-40S, 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 SIJ32X200-40S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X200-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 200mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X200-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X200-40S
The AirTAC SIJ32X200-40S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 40 mm on-site, giving a usable 160-200 mm extension out of the 200 mm nominal maximum. The direct replacement is the SAIJ32X200-40S, matching the interface, force, and adjust window.
The SAIJ successor retains the ISO 15552 mounting dimensions for direct reuse of FA, LB, and TC brackets, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X200-40S Is Used
Diverter Gate Positioning
Allows operators to fine-tune the extend stroke on-site by up to 40 mm to hit an exact diverter angle without swapping cylinders.
Variable Length Stopper
Adjusts the end-stop position for different package sizes on a 32 mm bore line, trimming the 200 mm stroke to the exact required length.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X200-40S with the SAIJ32X200-40S
To replace the discontinued SIJ32X200-40S, order the direct replacement SAIJ32X200-40S, which preserves the 32 mm bore, 200 mm max stroke, 40 mm adjust window, and G1/8 port. Choose the 40 mm adjust window if your application requires trimming the extend stroke between 160 and 200 mm; the stop screw sets the end position but is not a load lock. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B sensors (current AirTAC switches are used on the SAIJ). For stroke lengths of 300 mm or more, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X200-40S
- ✓ 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 SIJ32X200-40S FAQ
Yes, the SIJ32X200-40S is discontinued. The direct replacement is the SAIJ32X200-40S, which shares the same ISO 15552 interface, 32 mm bore, 200 mm stroke, 40 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded piston seal.
The external stop screw provides a 40 mm adjust window, allowing you to shorten the extend stroke from 200 mm down to 160 mm on-site.
