This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X100-30, 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 SIJ32X100-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30 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 SAIJ32X100-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30
The AirTAC SIJ32X100-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 100 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 70-100 mm extension. The stop sets the end position and is not a load lock.
As SIJ is end-of-life, the direct replacement is the SAIJ32X100-30, preserving the ISO 15552 interface, force, and mounting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnetic SKU cannot take a switch; for held loads use an external rod lock or SAIL/BSAI variant, as air cushions only decelerate.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30 Is Used
Light-Duty Parts Ejection
Tuning the extend stroke on-site by up to 30 mm allows operators to precisely set the ejection reach for varying part sizes without swapping cylinders.
Adjustable End Stops
Ideal for test fixtures requiring a variable hard-stop position between 70 and 100 mm, replacing complex external mechanical stop assemblies.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-30 with the SAIJ32X100-30
To replace the discontinued SIJ32X100-30, order the direct replacement SAIJ32X100-30, which retains the 32 mm bore, 100 mm stroke, 30 mm adjust window, G1/8 port, and FA/LB/TC mount compatibility. Choose the 30 mm adjust window if your extend stroke needs on-site tuning between 70 and 100 mm. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load guidance to prevent rod bearing wear. Remember the external stop screw sets end position but does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X100-30
- ✓ 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 SIJ32X100-30 FAQ
Yes, the SIJ32X100-30 is discontinued. The direct replacement is the SAIJ32X100-30, which maintains the same ISO 15552 interface, 32 mm bore, 100 mm stroke, 30 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 30 mm adjust window, allowing the extend stroke to be shortened from the 100 mm maximum down to 70 mm. The stop sets end position and is not a load lock.
