This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-10 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 SIJ80X150-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X150-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-10
The AirTAC SIJ80X150-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 150mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 10mm on-site, yielding a usable 140-150mm extend window. It delivers 2513N push and 2268N pull at 0.5MPa, features a 25mm rod, M20x1.5 thread, and a fixed G3/8 port. The exact drop-in replacement is the SAIJ80X150-10, matching the interface, force, and mounting.
The SAIJ successor retains ISO 15552 mounting interchangeability and incorporates an upgraded piston seal using two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, a computed buyer insight from the 0.5MPa push force yields a safe working load of roughly 1508N (about 60% of 2513N), or a vertical lift capacity of approximately 128kg with a 2:1 margin. Note this SKU lacks a magnet (-S) and cannot accept a sensor. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X150-10 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 SAIJ80X150-10 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 SIJ80X150-10 Is Used
Press Fit Tuning
Allows precise 140-150mm extend adjustment for pressing bearings, accommodating material thickness variations without remounting the actuator.
Divertor Gate Stroke Trim
Fine-tunes the extend end position on-site by up to 10mm to set the exact divert angle for varying package sizes on the line.
Pallet Stop Positioning
Adjusts the extend stop point in 10mm increments to handle mixed pallet depths, ensuring positive contact without repositioning the cylinder.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-10 with the SAIJ80X150-10
To replace the discontinued SIJ80X150-10, specify the drop-in SAIJ80X150-10, keeping the 80mm bore, 150mm nominal stroke, 10mm adjust window, and G3/8 port. When sizing both ways, the neighbouring 63mm bore provides 1559N push at 0.5MPa, while the 100mm bore offers 3927N push at 0.5MPa. Choose the 10mm adjust window if you need fine end-position tuning within a 140-150mm extend range; it is preferable to a fixed SAI with an external stop because it simplifies ISO 15552 mounting reuse. Mounting options include Basic, FA, LB, and TC. This SKU has no -S magnet and cannot support legacy CS1-B/DS1-B sensors. For strokes at or above 300mm, verify side-load limits to prevent guide wear. The external stop sets the end position but does not lock the load; for air-loss holding, select an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X150-10
- ✓ 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 SIJ80X150-10 FAQ
Yes, the SIJ80X150-10 is discontinued. The exact drop-in replacement is the SAIJ80X150-10. It shares the same ISO 15552 interface, 80mm bore, 150mm nominal stroke, 10mm adjust window, G3/8 port, and mounting options, while adding an upgraded piston seal.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa, with a theoretical max of 513kgf at 1.0MPa. The external stop screw provides a 10mm adjust window, allowing you to shorten the 150mm extend stroke down to 140mm on-site. The stop sets end position and is not a load lock.
