This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X150-40S, 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 SIJ32X150-40S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X150-40S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 150mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X150-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-40S
The AirTAC SIJ32X150-40S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder featuring a 32mm bore, 150mm nominal stroke, and a built-in piston magnet. It is discontinued, with the direct replacement being the SAIJ32X150-40S, retaining the same interface, G1/8 port, and force. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 110-150mm extension. The stop sets the end position but is not a load lock; use an external rod lock for held loads.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. You reuse existing FA, LB, or TC mounts, and the magnet enables legacy CS1-B/DS1-B sensors for position confirmation.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-40S Is Used
Adjustable End-Stop Forming
Pin insertion operations needing field stroke tuning to accommodate material thickness variations without changing the cylinder body.
Variable-Length Diverter
Sorting arms on packaging lines where the extend stroke must be shortened on-site by up to 40mm to handle different carton depths.
Tunable Clamping Fixture
Light-duty clamping stations requiring precise end-position adjustment via the external stop screw for varied part heights.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-40S with the SAIJ32X150-40S
To replace the discontinued SIJ32X150-40S, specify the direct replacement SAIJ32X150-40S, keeping the 32mm bore, 150mm stroke, 40mm adjust window, and G1/8 port. Choose the 40mm adjust window if your field tuning requires trimming the extend stroke by up to 40mm. Select FA, LB, or TC mounting based on your ISO 15552 fixture. The -S suffix indicates a built-in magnet for CS1-B/DS1-B switches. For strokes at or above 300mm, verify side-load guiding to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X150-40S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
