This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X40-30S, 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 SIJ32X40-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X40-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 40mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X40-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X40-30S
The AirTAC SIJ32X40-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 40 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 10-40 mm stroke window. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ32X40-30S, retaining the same interface, force, and port. The SAIJ family uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. A plain cylinder drifts on air loss; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X40-30S Is Used
Short-Stroke Clamping
Ideal for clamping parts where the exact contact point varies, using the 30 mm adjust screw to tune the 40 mm extend stroke on-site without changing the cylinder.
Transfer Pusher
Useful on conveyor lines to push items of varying widths, allowing operators to shorten the extend stroke by up to 30 mm to accommodate different product sizes.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X40-30S with the SAIJ32X40-30S
To replace the discontinued SIJ32X40-30S, order the SAIJ32X40-30S direct. It preserves the 32 mm bore, 40 mm stroke, 30 mm adjust window, G1/8 port, and M10x1.25 rod thread. Choose the 30 mm adjust window if your extend stroke needs field tuning between 10 and 40 mm. Mounting interfaces include Basic, FA, LB, and TC. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Because the 40 mm stroke is under 300 mm, side-load rod deflection is minimal. Remember the stop screw sets end position only; it does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X40-30S
- ✓ 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 SIJ32X40-30S FAQ
Yes, the AirTAC SIJ32X40-30S is discontinued. The direct replacement is the SAIJ32X40-30S. It shares the same ISO 15552 interface, 32 mm bore, 40 mm stroke, 30 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded piston seal and adds SAIL and BSAI lock variants.
The external stop screw provides a 30 mm adjust window, allowing the 40 mm extend stroke to be shortened to a minimum of 10 mm on-site.
