This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X50-30S, 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 SIJ32X50-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 50mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X50-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30S
The AirTAC SIJ32X50-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore, G1/8 port, and a 50 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 20-50 mm extension window. The stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. This unit includes a piston magnet for legacy CS1-B/DS1-B switches.
As an end-of-life product, the direct replacement is the SAIJ32X50-30S, sharing the same interface, force, port, and mounting. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ32X50-30S 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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAIJ32X50-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30S Is Used
Light-Actuation Clamping
Tuning the extend contact point on small pneumatic clamps where a 20-50 mm stroke window prevents over-travel on delicate workpieces.
Sensor Probe Positioning
Adjusting the extension length of a testing probe so it engages the target precisely without requiring mechanical shim plates.
Miniature Diverter Arms
Setting the exact push distance for lightweight conveyor diverters to accommodate varying product widths on the fly.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X50-30S with the SAIJ32X50-30S
To replace the discontinued SIJ32X50-30S, order the direct replacement SAIJ32X50-30S, retaining the 32 mm bore, 50 mm nominal stroke, 30 mm adjust window, G1/8 port, and -S magnet. Size both ways using 0.5 MPa push force: the 40 mm bore yields 628 N, while a smaller option requires confirming from datasheet. The 30 mm adjust window is ideal for precise end-position tuning without machining. Mounting options include Basic, FA, LB, and TC. The -S suffix provides a piston magnet for CS1-B/DS1-B switches; SAIJ uses current AirTAC switches. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X50-30S
- ✓ 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 SIJ32X50-30S FAQ
Yes, the SIJ32X50-30S is discontinued. The direct replacement is the SAIJ32X50-30S, which shares the same ISO 15552 interface, 32 mm bore, 50 mm stroke, 30 mm adjust window, G1/8 port, and mounting options.
The external stop screw offers a 30 mm adjust window, allowing you to trim the 50 mm nominal extend stroke down to 20 mm on-site.
