This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-50, 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 SIJ32X175-50
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-50 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X175-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-50
The AirTAC SIJ32X175-50 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. The external stop screw trims the extend stroke by up to 50mm on-site, yielding a usable 125-175mm extension. The direct replacement is the SAIJ32X175-50, sharing the G1/8 port, M10x1.25 rod thread, and 27mm cushions.
The SAIJ successor retains the ISO 15552 mounting interface but uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure. This non-magnetic SKU lacks a -S piston magnet and cannot accept a switch. The stop sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-50 Is Used
Variable Depth Drilling
Dial in precise 125-175mm extend positions on a drilling head without swapping cylinders, using the 50mm stop screw to adapt to material thicknesses on-site.
Adjustable Carton Sealing
Accommodate fluctuating package heights on a sealing line by trimming the extend stroke up to 50mm, ensuring consistent contact pressure for varied box profiles.
Tunable Diverting Gate
Fine-tune the actuation reach of a conveyor sorting gate between 125mm and 175mm to handle different product widths without re-mounting hardware.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-50 with the SAIJ32X175-50
To replace the discontinued SIJ32X175-50, order the direct replacement SAIJ32X175-50, keeping the same 175mm nominal stroke, 50mm adjust window, G1/8 port, and FA/LB/TC mountings. The 50mm adjust window allows field-tuning the extend stroke down to 125mm without external stops. This SKU has no -S magnet, so it cannot use sensors. For strokes over 300mm, verify side-load limits. The stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-50
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
