This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X20-10, 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 SIJ32X20-10
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X20-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 20mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X20-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X20-10
The AirTAC SIJ32X20-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, giving a usable 10-20 mm stroke window from the 20 mm nominal maximum. Note this SKU lacks a magnet (-S), so it cannot accept a magnetic switch.
The SIJ series is discontinued; the direct replacement is the SAIJ32X20-10, retaining the same interface, force, and port. The SAIJ upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets end position only—it is not a lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X20-10 Is Used
Short-Stroke Clamping
Precise parts clamping where the 10 mm on-site adjust window dials in the exact grip position without swapping cylinders.
Datum Positioning Stops
Adjustable end stops for lightweight fixtures, allowing operators to trim the 20 mm extend stroke by up to 10 mm for varying part widths.
Ejector Stroke Tuning
Small ejection mechanisms needing field stroke tuning to prevent over-travel, utilizing the 27 mm adjustable cushion for soft end-of-stroke deceleration.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X20-10 with the SAIJ32X20-10
To replace the discontinued SIJ32X20-10, order the direct replacement SAIJ32X20-10, which preserves the 32 mm bore, 20 mm nominal stroke, 10 mm adjust window, G1/8 port, and mounting footprint. The 10 mm adjust window is ideal for fine-tuning the extend end position without machining spacers; remember the stop screw is not a load lock, so for holding loads on air loss, specify an external rod lock or the SAIL/BSAI variant. Reuse existing FA, LB, or TC ISO 15552 mounts. Because this SKU lacks the -S magnet, it cannot support position sensing; if sensing is required, select a -S SAIJ model. For any stroke over 300 mm, carefully manage side loading to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X20-10
- ✓ 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 SIJ32X20-10 FAQ
Yes, the SIJ32X20-10 is discontinued. The direct replacement is the SAIJ32X20-10, which matches the ISO 15552 interface, 32 mm bore, 20 mm stroke, 10 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw provides a 10 mm adjust window, allowing you to shorten the 20 mm nominal extend stroke down to 10 mm on-site. The stop sets end position only and is not a load lock.
