This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X800-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X800-40 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 SIJ80X800-40
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X800-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-40
The AirTAC SIJ80X800-40 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a nominal 800 mm extend stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 760-800 mm window. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. It features a Ø25 mm rod, M20x1.5 rod thread, 36 mm adjustable air cushions, and a fixed G3/8 port.
This SIJ model is discontinued; the exact drop-in replacement is the SAIJ80X800-40, retaining the same interface, force, and adjustability. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. From a computed buyer insight, 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 magnet (-S) and cannot take a sensor; the stop screw sets end position but is not a load 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 SAIJ80X800-40 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 SIJ80X800-40 Is Used
Package Diverter Stroke Tuning
Trimming the extend stroke by up to 40 mm on-site allows precise divergence of varying carton widths without swapping the entire actuator.
Adjustable End Stop Pressing
External stop screw provides a rigid mechanical end position for light pressing tasks, adjustable between 760 and 800 mm to accommodate material thickness variations.
Long-Reach Pallet Stopper
The 800 mm stroke reaches across conveyor lanes to halt pallets, with the 40 mm window allowing exact positioning calibration during commissioning.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-40 with the SAIJ80X800-40
To replace the discontinued SIJ80X800-40, order the drop-in SAIJ80X800-40, which preserves the G3/8 port, 40 mm adjust window, and ISO 15552 mounting. When sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa; this 80 mm bore provides 3518 N at that same pressure. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 760 and 800 mm. Mounting options include Basic, FA, LB, and TC. Because this is a non-magnet SKU, you cannot mount legacy CS1-B or DS1-B sensors. For the 800 mm stroke, use external guides to prevent rod bending and side-load damage. The stop screw only sets the end position; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X800-40
- ✓ 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 SIJ80X800-40 FAQ
Yes, the SIJ80X800-40 is discontinued. The exact drop-in replacement is the SAIJ80X800-40, which shares the same ISO 15552 interface, 800 mm stroke, 40 mm adjust window, G3/8 port, and 36 mm cushion. The SAIJ family also adds an upgraded two-piece Y-shaped piston seal for longer life.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a 513 kgf max at 1.0 MPa. The external stop screw shortens the extend stroke by up to 40 mm on-site (usable 760-800 mm). The stop sets end position only; it is not a load lock, so use an external rod lock for held loads.
