This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X700-40S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X700-40S 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 SIJ80X700-40S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40S 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 SAIJ80X700-40S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40S
The AirTAC SIJ80X700-40S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 700 mm nominal stroke and a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 660-700 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 SAIJ80X700-40S, matching the interface, force, and port. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. Force is 2513 N push / 2268 N pull at 0.5 MPa. Computed insight: safe working load is ~1508 N (60% of push), allowing a 128 kg vertical lift with a 2:1 margin. Plain cylinders drift on air loss; use SAIL/BSAI or an external rod lock to hold loads.

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 SIJ80X700-40S Is Used
Variable Stroke Pressing
Dialing in the exact 660-700 mm extend position on-site allows a press to accommodate varying material thicknesses without machining custom spacers.
Adjustable Transfer Pusher
Trimming the extend stroke by up to 40 mm lets a transfer pusher adapt to different package widths on the line quickly and reliably.
End-Stop Positioning
Setting the precise end position for pallet stops ensures accurate alignment, with the external screw providing field flexibility for varied pallet depths.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40S with the SAIJ80X700-40S
To replace the discontinued SIJ80X700-40S, order the drop-in SAIJ80X700-40S, reusing your existing ISO 15552 FA, LB, or TC mounts. For sizing both ways: the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 660 and 700 mm. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Because the 700 mm stroke exceeds 300 mm, verify side-load limits and use external guides to prevent rod bending. The stop screw sets end position but does not lock the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X700-40S
- ✓ 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 SIJ80X700-40S FAQ
Yes, the SIJ80X700-40S is discontinued. The exact drop-in replacement is the SAIJ80X700-40S, which shares the same ISO 15552 interface, 80 mm bore, 700 mm stroke, 40 mm adjust window, G3/8 port, and mounting options. The SAIJ family also adds upgraded piston seals and lock variants like SAIL and BSAI.
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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 40 mm adjust window, allowing you to shorten the 700 mm extend stroke down to 660 mm on-site. The stop sets position and is not a load lock.
