This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X700-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X700-75 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 SIJ80X700-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X700-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75
The AirTAC SIJ80X700-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 700 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 625-700 mm end position. The stop sets the end position and is not a load lock. This 80 mm bore uses a G3/8 port, a 25 mm rod, and 36 mm adjustable cushions. The exact drop-in replacement is the SAIJ80X700-75, sharing the same interface, force, and mounting.
Force output is 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. A computed buyer insight: the safe working load is roughly 1508 N (60% of the 0.5 MPa push), allowing a 128 kg vertical lift with a 2:1 margin. The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure. This non-magnetic SKU cannot take a switch. For a 700 mm stroke, use external guides to prevent rod bending.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75 Is Used
Variable Stroke Pressing
Dialing in the exact contact position on a 625-700 mm press stroke without swapping cylinders, using the external stop screw to set the final extend position precisely.
Adjustable Transfer Diverter
Tuning the extend reach on a long-transfer diverter arm on-site to accommodate different product widths, trimming the extend stroke by up to 75 mm as needed.
Variable Height Indexing
Setting precise mechanical end-stops for a long vertical indexing lift where the exact top position must be adjusted during commissioning without reprogramming valves.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-75 with the SAIJ80X700-75
To replace the discontinued SIJ80X700-75, order the drop-in SAIJ80X700-75, which preserves the ISO 15552 mounting interface, G3/8 port, and 75 mm adjust window. 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. Choose the 75 mm adjust window if you need on-site tuning of the extend end position from 625 to 700 mm. Mounting options include FA, LB, and TC brackets. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B or DS1-B sensors. Since the 700 mm stroke exceeds 300 mm, ensure external guides are used to manage side-load and prevent rod bending. Remember that a plain cylinder does not hold loads on air loss; for held loads use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X700-75
- ✓ 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 SIJ80X700-75 FAQ
Yes, the SIJ80X700-75 is discontinued. The exact drop-in replacement is the SAIJ80X700-75. It shares the same ISO 15552 interface, 80 mm bore, 700 mm stroke, 75 mm adjust window, G3/8 port, and mounting options, while adding an upgraded two Y-shaped one-way 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 theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 75 mm adjust window, allowing you to trim the extend stroke from the 700 mm maximum down to 625 mm. The stop sets end position and is not a load lock.
