This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X700-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X700-30 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 SIJ80X700-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-30 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 SAIJ80X700-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-30
The AirTAC SIJ80X700-30 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 670-700 mm window from the 700 mm nominal maximum. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa. The exact drop-in replacement is the SAIJ80X700-30, matching the interface, bore, force, and mounting.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), translating to a 128 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use SAIL or BSAI variants for held loads. This non-magnet SKU cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X700-30 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 SAIJ80X700-30 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 SIJ80X700-30 Is Used
Press Fit Tuning
Dial in the exact 670-700 mm extend position on-site to seat bearings without over-traveling, using the 2513 N push force at 0.5 MPa.
Divertor Stroke Trimming
Adjust the 30 mm stop window to fine-tune the divert arm reach for varying package widths without repositioning the G3/8 ported cylinder.
Pallet Stop Positioning
Set a precise mechanical end-stop for pallet feeds, leveraging the 128 kg vertical lift capacity while ensuring external guides handle the 700 mm stroke.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-30 with the SAIJ80X700-30
To replace the discontinued SIJ80X700-30, use the drop-in SAIJ80X700-30. 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. The 30 mm adjust window is ideal for final mechanical timing without machining spacers. Reuse FA, LB, or TC mounts via the ISO 15552 interface. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For the 700 mm stroke, use external guides to prevent rod bending and side-load damage. Remember the stop screw sets end position but is not a lock; drifting occurs on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X700-30
- ✓ 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 SIJ80X700-30 FAQ
