This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X300-30, 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 SIJ32X300-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X300-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X300-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-30
The AirTAC SIJ32X300-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 300 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 270-300 mm end position. This SKU lacks a magnet (-S) and cannot accept a magnetic switch.
Because SIJ is end-of-life, the direct replacement is the SAIJ32X300-30—identical ISO 15552 interface, force, and mounting. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note the stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ32X300-30 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-30 Is Used
Light-Actuation End-Stop Tuning
Trimming the 300 mm extend stroke by up to 30 mm on-site to dial in exact contact points for light press fits without machining hard stops.
Variable-Length Ejector Stroke
Adjusting the extend end position on a 32 mm bore ejection gate to accommodate varying product lengths on a packaging line.
Prototype Tooling Setup
Fine-tuning the extend reach during machine commissioning to find the optimal 270-300 mm stroke before locking the stop screw.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-30 with the SAIJ32X300-30
To replace the discontinued SIJ32X300-30, order SAIJ32X300-30 for a direct. Choose the 30 mm adjust window if your extend end-position needs on-site tuning between 270-300 mm. Mounting reuses standard ISO 15552 attachments (FA, LB, TC). As this unit has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors; confirm sensing needs before swapping. For the 300 mm stroke, add external guides to prevent rod bending and manage side loads. The stop screw is not a lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X300-30
- ✓ 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 SIJ32X300-30 FAQ
Yes, the AirTAC SIJ32X300-30 is discontinued. The direct replacement is the SAIJ32X300-30, which shares the same ISO 15552 interface, 32 mm bore, 300 mm stroke, 30 mm adjust window, G1/8 port, and mounting options. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.
The external stop screw provides a 30 mm adjust window, shortening the extend stroke from the 300 mm maximum down to 270 mm. The stop sets end position only and is not a load lock; use an external rod lock for held loads.
