This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X30-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X30-30 in place of this model. 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X30-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X30-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 30mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X30-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X30-30
The AirTAC SIJ80X30-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 0-30 mm extend window from the 30 mm nominal maximum. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. It features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a fixed G3/8 port.
As the SIJ line is end-of-life, the exact drop-in replacement is the SAIJ80X30-30, retaining the same ISO 15552 mounting interface, bore, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet, so it cannot accept a sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X30-30 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAIJ80X30-30 produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X30-30 Is Used
Short-Stroke Clamping
Adjustable end-position clamping of cast parts where the exact 0-30 mm extend contact point must be tuned on-site without changing the cylinder body.
Transfer Diverter
Actuating a diverter gate on a conveyor line where product sizes vary, requiring quick field adjustment of the extend stroke within the 30 mm window.
Packaging Stopper
Deploying a physical stop for cartons of varying widths, using the external screw to precisely set the 0-30 mm protrusion distance for each run.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X30-30 with the SAIJ80X30-30
To replace the discontinued SIJ80X30-30, order the drop-in SAIJ80X30-30, matching the 80 mm bore, 30 mm nominal stroke, 30 mm adjust window, and G3/8 port. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N; choose based on your exact force needs. Reuse existing FA, LB, or TC ISO 15552 mounts. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. The external stop screw sets the end position but is not a load lock; for load holding on air loss, use an external rod lock or SAIL/BSAI variant. As the stroke is under 300 mm, side-load rod deflection is minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X30-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X30-30 FAQ
Yes, the SIJ80X30-30 is discontinued. The exact drop-in replacement is the SAIJ80X30-30. It shares the same ISO 15552 interface, 80 mm bore, 30 mm stroke, 30 mm adjust window, G3/8 port, and mounting options, but adds an upgraded SAI piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa, with a 513 kgf max at 1.0 MPa. The external stop screw provides a 30 mm adjust window, allowing you to trim the extend stroke by up to 30 mm on-site. The stop sets end position only; it is not a load lock.
