This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-100, 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 SIJ32X175-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100 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 SAIJ32X175-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100
The AirTAC SIJ32X175-100 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, discontinued and replaced by the SAIJ32X175-100. It uses an external stop screw to trim the extend stroke by up to 100 mm on-site, giving a usable 75-175 mm stroke. The 32 mm bore uses a G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions.
The SAIJ direct keeps the exact ISO 15552 mounting interface, bore, and force. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a -S magnet and cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100 Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to match different material thicknesses, preventing drill bit breakthrough without changing the cylinder.
Variable Height Carton Sealing
Trims the extend stroke up to 100 mm to seal cartons of varying heights on the same line, ensuring consistent flap contact.
Adjustable Transfer Stops
Sets precise stop positions for different product lengths on a conveyor, allowing quick changeovers without repositioning hardware.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100 with the SAIJ32X175-100
To replace this discontinued model, order the direct replacement SAIJ32X175-100, keeping the same 100 mm adjust window and ISO 15552 interface. The 100 mm adjust window lets you set exact end positions from 75 to 175 mm. Choose FA, LB, or TC mounting to reuse existing holes. Because this SKU lacks a -S magnet, it cannot accept a switch; add -S if sensing is needed. For strokes over 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-100
- ✓ 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 SIJ32X175-100 FAQ
Yes, the SIJ32X175-100 is discontinued. The direct replacement is the SAIJ32X175-100, which matches the ISO 15552 interface, 32 mm bore, 175 mm stroke, 100 mm adjust window, G1/8 port, and force ratings.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from 175 mm down to 75 mm. The stop sets end position and is not a load lock.
