This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X225-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X225-10 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 SIJ80X225-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X225-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10
The AirTAC SIJ80X225-10 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 225 mm maximum extend stroke. An external stop screw lets you trim the extend stroke on-site by up to 10 mm, yielding a usable 215-225 mm end position. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. It features a 25 mm piston rod, an M20x1.5 rod-end thread, and a G3/8 air port.
This SIJ model is discontinued and the direct drop-in replacement is the SAIJ80X225-10, retaining the exact ISO 15552 interface, force, and porting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a 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 has no -S magnet and cannot take a sensor; the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X225-10 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 SAIJ80X225-10 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 SIJ80X225-10 Is Used
Press Fit Tuning
Final insertion depth of a bearing requires minor on-site tuning. The 10 mm stop screw window trims the 225 mm extend stroke precisely without remounting the actuator.
Divertor End-Stop
A divertor arm needs its full reach slightly shortened to match a new lane width. The external screw adjusts the end position dynamically for product changes.
Carton Flap Folder
Folding mechanics require a specific extend endpoint that varies by carton thickness. The adjustable stop provides the exact 215-225 mm stroke needed for consistent folding.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10 with the SAIJ80X225-10
To replace the discontinued SIJ80X225-10, order the drop-in SAIJ80X225-10, matching the 225 mm stroke, 10 mm adjust window, and G3/8 port. Size both ways using 0.5 MPa forces: the 63 mm bore yields 1559 N push / 1402 N pull, while the 100 mm bore yields 3927 N push / 3681 N pull. Choose the 10 mm adjust window when you need minor on-site end-position tuning between 215-225 mm. Mounting interfaces include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For this 225 mm stroke, keep side-load within standard ISO 15552 tolerances. The external stop sets the end position but does not hold the load on air loss; for held loads use an external rod lock or the SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-10
- ✓ 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 SIJ80X225-10 FAQ
Yes, the SIJ80X225-10 is discontinued. The exact drop-in replacement is the SAIJ80X225-10, offering the same ISO 15552 interface, 80 mm bore, 225 mm stroke, 10 mm adjust window, and G3/8 port. The SAIJ family also uses an upgraded two Y-shaped one-way 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, and 4523 N push at 0.9 MPa. The theoretical max is 513 kgf at 1.0 MPa. The external stop screw offers a 10 mm adjust window, shortening the extend stroke from 225 mm down to 215 mm. The stop sets end position and is not a load lock.
