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

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75SN
The AirTAC SIJ32X150-75SN is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The direct replacement is the SAIJ32X150-75SN, retaining the G1/8 port, 12mm rod, and mounting interface. An external stop screw lets you trim the extend stroke by up to 75mm on-site, giving a usable forward travel of 75-150mm. This stop sets the end position but is not a load lock.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. The -SN config gives an NBR seal (-20 to +70C) and a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75SN Is Used
Variable Depth Drilling
Trimming the extend stroke by up to 75mm on-site allows a 32mm bore actuator to hit multiple material depths without swapping cylinders.
Adjustable Pusher Stroke
A packaging line can fine-tune the 75-150mm forward travel to push varying box sizes accurately onto a divert lane.
Variable Position Stops
External stop screw adjustment lets operators change the end position for different pallet heights quickly without reprogramming controls.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X150-75SN with the SAIJ32X150-75SN
To replace the discontinued SIJ32X150-75SN, order the SAIJ32X150-75SN direct; it preserves the 150mm nominal stroke, 75mm adjust window, and ISO 15552 mounting. Choose the 75mm adjust window if your application requires on-site tuning of the extend stroke from 75 to 150mm. Mounting attachments (FA, LB, TC) reuse the ISO 15552 interface. The -S magnet supports position sensing. For strokes of 300mm or longer, verify side-load limits to prevent guide wear. Remember the stop screw sets end position; it is not a lock, and a plain cylinder drifts on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X150-75SN
- ✓ 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 SIJ32X150-75SN FAQ
Yes, the SIJ32X150-75SN is discontinued. The direct replacement is the SAIJ32X150-75SN. It shares the same ISO 15552 interface, 32mm bore, 150mm stroke, 75mm adjust window, G1/8 port, and force ratings.
The external stop screw provides a 75mm adjust window, allowing the extend stroke to be shortened from the 150mm maximum down to 75mm. Speed is 30-800mm/s.
