This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X100-30SN, 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 SIJ32X100-30SN
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X100-30SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30SN
The AirTAC SIJ32X100-30SN is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the direct replacement SAIJ32X100-30SN. Its external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 70-100mm extend range out of the 100mm nominal maximum. The SAIJ replacement reuses the exact ISO 15552 mounting interface and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The stop screw sets the end position but is not a lock; without live air the piston drifts, so use an external rod lock or SAIL/BSAI variant for held loads. This NBR-sealed unit operates from -20 to +70C, includes a piston magnet for CS1-B/DS1-B sensors, and runs at 30-800mm/s.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30SN Is Used
Short-stroke clamping fixtures
Allows operators to dial in the exact 70-100mm clamping extension on-site to accommodate varying part tolerances without machining new stops.
Variable-position diverters
Fine-tunes the extend stroke by up to 30mm to adjust the deflection angle of a sorting gate directly at the conveyor line.
Light-duty pressing stops
Sets a precise mechanical lower limit for 32mm bore pressing tasks, ensuring consistent depth without relying solely on valve timing.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30SN with the SAIJ32X100-30SN
To replace the discontinued SIJ32X100-30SN, order the direct replacement SAIJ32X100-30SN, keeping the 32mm bore, 100mm stroke, 30mm adjust window, G1/8 port, and M10x1.25 rod thread. Choose the 30mm adjust window if your fixture needs on-site extend tuning between 70 and 100mm; the stop screw sets end position but does not lock the load. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix means a magnet is present for legacy CS1-B/DS1-B switches (the SAIJ uses current switches). For strokes >=300mm, verify side-load guidance to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X100-30SN
- ✓ 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 SIJ32X100-30SN FAQ
Yes, the SIJ32X100-30SN is discontinued. The direct replacement is the SAIJ32X100-30SN. It shares the same ISO 15552 interface, 32mm bore, 100mm nominal stroke, 30mm adjust window, G1/8 port, and mounting options, while adding an upgraded piston seal.
The external stop screw provides a 30mm adjust window, allowing the extend stroke to be shortened from the 100mm maximum down to 70mm on-site. The stop sets position but is not a load lock.
