This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X80-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X80-10 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 SIJ80X80-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X80-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-10
The AirTAC SIJ80X80-10 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder. This discontinued unit is fully replaced by the drop-in SAIJ80X80-10, retaining the G3/8 port, M20x1.5 rod, and 36mm cushions. An external stop screw lets you trim the extend stroke by up to 10mm on-site, yielding a 70-80mm usable window from the 80mm nominal maximum. The stop sets end position; it is not a load lock.
At 80mm, force is 2513N push and 2268N pull at 0.5MPa, reaching 4523N at 0.9MPa. A safe working load is roughly 1508N (60% of the 0.5MPa push), equating to a 128kg vertical lift with a 2:1 margin. The SAIJ successor adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure. This non-magnet SKU cannot take a switch; for held loads use SAIL/BSAI or an external rod lock.

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 SAIJ80X80-10 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 SIJ80X80-10 Is Used
Press Fit Calibration
Trimming the extend stroke by up to 10mm on-site allows operators to dial in the exact insertion depth for bearing press fits without machining custom spacers.
Divertor Gate Positioning
Adjusting the extend endpoint precisely sets the conveyor divertor gate angle on-site, accommodating varying package widths on the production line.
Sealing Head Clearance
Fine-tuning the down-stroke by up to 10mm ensures the sealing head contacts cartons perfectly, compensating for minor material thickness variations.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-10 with the SAIJ80X80-10
To replace the SIJ80X80-10, order the drop-in SAIJ80X80-10 to reuse your ISO 15552 FA, LB, or TC mounts. For sizing both ways: the 63mm bore yields 2182N push at 0.7MPa, while the 100mm bore yields 5497N at 0.7MPa. The 10mm adjust window is ideal for fine-tuning the extend endpoint without shims. This base model lacks the -S magnet, so it cannot accept legacy CS1-B/DS1-B sensors. Because the 80mm stroke is under 300mm, side-load rod deflection is minimal. Remember that a plain cylinder drifts on air loss; the cushion only decelerates, so use an external rod lock for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X80-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-10 FAQ
Yes, the SIJ80X80-10 is discontinued. The exact drop-in replacement is the SAIJ80X80-10, offering the same ISO 15552 interface, 80mm stroke, 10mm adjust window, G3/8 port, and 4523N push force at 0.9MPa.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N at 0.9MPa, with a 513kgf max at 1.0MPa. The external stop screw provides a 10mm on-site stroke-trim window, allowing a usable extend stroke of 70-80mm. The stop sets end position and is not a load lock.
