This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X150-50S, 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 SIJ32X150-50S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X150-50S 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 SAIJ32X150-50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-50S
The AirTAC SIJ32X150-50S 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 50mm on-site, giving a usable 100-150mm range from the 150mm nominal maximum.
This end-of-life model drops in directly to the SAIJ32X150-50S, retaining the exact bore, force, adjust window, and mounting interface. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop sets end position but is not a load lock; for held loads use SAIL/BSAI or an external rod lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-50S Is Used
Tooling Positioning
Trimming the extend stroke by up to 50mm on-site to dial in exact contact positions for varying workpiece heights without machining new stops.
Diverter Gate Adjustment
Field-tuning the 100-150mm extend stroke to alter the deflection angle of a sorting gate for different package widths on the line.
Pallet Stop Tuning
Adjusting the end position on the fly to handle mixed pallet depths, ensuring the external stop screw sets the precise resting point.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-50S with the SAIJ32X150-50S
To replace the discontinued SIJ32X150-50S, order the exact direct replacement SAIJ32X150-50S to reuse your ISO 15552 mounting and G1/8 porting. To size both ways, the neighbouring 40mm bore raises push force to 628N at 0.5MPa, while dropping to a smaller bore is not standard below 32mm. Choose the 50mm adjust window if your field stroke tuning requires trimming the extend by up to 50mm; the SAIJ family keeps the same window. Mounting options include Basic, FA, LB, and TC. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches (current AirTAC switches are used on the SAIJ). For stroke lengths of 300mm or more, verify side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X150-50S
- ✓ 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 SIJ32X150-50S FAQ
Yes, the SIJ32X150-50S is discontinued. The direct replacement is the SAIJ32X150-50S, offering the same ISO 15552 interface, 32mm bore, 150mm nominal stroke, 50mm adjust window, and G1/8 port.
The external stop screw window is 50mm, allowing you to shorten the 150mm extend stroke down to 100mm on-site.
