This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X150-75STC, 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 SIJ32X150-75STC
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75STC 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 SAIJ32X150-75STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75STC
The AirTAC SIJ32X150-75STC is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 75-150 mm extend range from the 150 mm nominal maximum. The 32 mm bore features a 12 mm rod, M10x1.25 thread, 27 mm adjustable cushions, G1/8 port, and 30-800 mm/s speed.
The direct replacement is the SAIJ32X150-75STC, retaining the same ISO 15552 interface, TC mounting, and force. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Note the stop screw sets end position but is not a load lock; cylinders drift on air loss. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75STC Is Used
Variable Pitch Push Stations
Adjusting the extend stroke on-site by up to 75 mm allows operators to tune push-off distances for varying product sizes without changing the cylinder.
Adjustable Transfer Diverters
The 75-150 mm usable extend range accommodates different package widths on a conveyor line, providing flexible routing via the TC mount.
Customizable Stop Fences
Trimming the extend stroke on-site enables precise pallet positioning fences that can be quickly readjusted as pallet dimensions change.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75STC with the SAIJ32X150-75STC
To replace the discontinued SIJ32X150-75STC, use the direct replacement SAIJ32X150-75STC, matching the 32 mm bore, 150 mm stroke, 75 mm adjust window, G1/8 port, and TC mount. Choose the 75 mm adjust window if your application requires field tuning the extend stroke within a 75-150 mm range. The TC mounting accessory attaches via the ISO 15552 interface. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B sensor accuracy. For strokes >=300 mm, verify side-load limits to prevent rod binding. Remember, the stop screw sets end position but is not a load lock; for held loads use an external rod lock, pilot-operated check valve, or SAIL/BSAI variant.
Replacement checklist

- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
