This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X400-100, 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 SIJ32X400-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X400-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 400mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X400-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-100
The AirTAC SIJ32X400-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. A 400 mm nominal extend stroke is shortened on-site by an external stop screw, offering a 100 mm trim window for a usable 300-400 mm range. The stop sets the end position but is not a load lock; loads drift on air loss.
The direct replacement is the SAIJ32X400-100, reusing the same ISO 15552 mounting interface, force, and adjustability. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-100 Is Used
Variable Depth Drilling
Tuning the extend stroke by up to 100 mm on-site to accommodate varying material thicknesses without swapping the entire actuator.
Adjustable Pusher Stops
Altering the extend end position for different package sizes on a packaging line, using the external stop screw to set the precise 300-400 mm reach.
Format Change Diverters
Quickly reconfiguring diverter arm extension lengths during product format changes, ensuring the exact end position is met without re-plumbing.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-100 with the SAIJ32X400-100
To replace the discontinued SIJ32X400-100, order the direct replacement SAIJ32X400-100, which preserves the 100 mm adjust window, 400 mm max stroke, G1/8 port, and FA/LB/TC mounting. This SKU lacks a -S magnet, so it cannot accept a magnetic switch for position sensing. Because the 400 mm stroke exceeds 300 mm, verify side-load limits and use external guides to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X400-100
- ✓ 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 SIJ32X400-100 FAQ
Yes, the SIJ32X400-100 is discontinued. The direct replacement is the SAIJ32X400-100, which maintains the same ISO 15552 interface, 400 mm nominal stroke, 100 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 100 mm trim window, allowing the 400 mm extend stroke to be shortened to 300 mm on-site. The stop sets end position and is not a load lock.
