This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X200-50, 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 SIJ32X200-50
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X200-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 200mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X200-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X200-50
The AirTAC SIJ32X200-50 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 200mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 50mm on-site, yielding a usable 150-200mm extension. The direct replacement is the SAIJ32X200-50, matching the G1/8 port, M10x1.25 rod thread, and 27mm adjustable cushion. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
The stop screw sets the end position but is not a load lock; without live air the piston drifts. For held loads use an external rod lock or the SAIL/BSAI variants. This non-magnet SKU cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X200-50 Is Used
Variable Depth Drilling Jigs
Tune the 150-200mm extend stroke on-site to accommodate multiple material thicknesses without re-engineering the fixture.
Adjustable Sealing Heads
Trim the extend stroke by up to 50mm to adapt to varying carton dimensions on a packaging line using the G1/8 port.
Multi-Position Ejector Pins
Set the external stop screw to define a precise ejection depth for parts of varying heights without adding valves.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X200-50 with the SAIJ32X200-50
To replace the discontinued SIJ32X200-50, order the direct replacement SAIJ32X200-50, reusing your existing FA, LB, or TC ISO 15552 mounts. The 50mm adjust window allows field-tuning the extend stroke between 150mm and 200mm. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add an external switch bracket if sensing is required. For strokes of 300mm or longer, verify your side-load limits to prevent guide wear. Remember the stop screw only sets end position and does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X200-50
- ✓ 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 SIJ32X200-50 FAQ
Yes, the SIJ32X200-50 is discontinued. The direct replacement is the SAIJ32X200-50, offering the same ISO 15552 interface, 32mm bore, 200mm stroke, 50mm adjust window, and G1/8 port. The SAIJ features an upgraded piston seal for longer life.
The external stop screw allows trimming the extend stroke by up to 50mm on-site, giving a usable extension of 150-200mm. The stop sets end position only; it is not a load lock.
