This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X400-10, 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 SIJ32X400-10
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X400-10 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 SAIJ32X400-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-10
The AirTAC SIJ32X400-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 400 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable extend range of 390-400 mm. The stop sets the end position but is not a load lock. As the SIJ line is end-of-life, the direct replacement is the SAIJ32X400-10, retaining the same interface, force, and adjust window.
The SAIJ successor incorporates an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnetic SKU cannot take a switch. Note that a plain cylinder drifts on air loss; for held loads use an external rod lock or SAIL/BSAI variant. At 400 mm stroke, use external guides to prevent rod bending.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-10 Is Used
Micro-Position Pressing
Trimming the extend stroke by up to 10 mm on-site allows exact end-position tuning for light pressing tasks without remachining hard stops.
Divertor Gate Adjustment
Field-tuning the 390-400 mm extend stroke lets operators fine-tune a conveyor diverting gate's reach to accommodate varying product sizes.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-10 with the SAIJ32X400-10
To replace the discontinued SIJ32X400-10, order the direct replacement SAIJ32X400-10, matching the 32 mm bore, 400 mm nominal stroke, and 10 mm adjust window. Choose the 10 mm adjust window if you only need micro-trimming of the extend end-position. Mounting reuses ISO 15552 attachments including FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch; add -S for legacy CS1-B/DS1-B sensor accuracy. Finally, at 400 mm stroke, external guides are required to manage side-load and prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X400-10
- ✓ 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 SIJ32X400-10 FAQ
Yes, the SIJ32X400-10 is discontinued. The direct replacement is the SAIJ32X400-10. It shares the identical ISO 15552 interface, 32 mm bore, 400 mm stroke, 10 mm adjust window, G1/8 port, and mounting options, but adds an upgraded piston seal.
The external stop screw provides a 10 mm adjust window, making the usable extend stroke 390-400 mm. The stop sets end position and is not a load lock.
