This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X350-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X350-75S 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 SIJ80X350-75S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X350-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-75S
The AirTAC SIJ80X350-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 275-350 mm range from the 350 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa via a G3/8 port. The exact drop-in replacement is the SAIJ80X350-75S, retaining the same interface, force, and mounting.
The SAIJ upgrade features an upgraded two-piece Y-shaped piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is ~1508 N (60% of push@0.5), yielding a ~128 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock. For held loads, use an external rod lock or SAIL/BSAI variant.

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 SAIJ80X350-75S 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 SIJ80X350-75S Is Used
Variable Depth Boring
Trimming the 350 mm extend stroke by up to 75 mm on-site to hit exact boring depths without swapping the entire actuator.
Adjustable Push-off Station
Tuning the extend end position to push varying carton widths off a belt, using the external stop screw for rapid field changes.
Tiered Pallet Stops
Setting intermediate stop points for different pallet heights, relying on the 80 mm bore's 2513 N push force at 0.5 MPa.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-75S with the SAIJ80X350-75S
To replace the SIJ80X350-75S, order the drop-in SAIJ80X350-75S, keeping the -S magnet for current AirTAC switches. Size both ways: the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 75 mm adjust window to cover your on-site extend trimming. FA, LB, and TC mountings reuse ISO 15552 dimensions. At 350 mm stroke, support external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X350-75S
- ✓ 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 SIJ80X350-75S FAQ
Yes, the SIJ80X350-75S is discontinued. The exact drop-in replacement is the SAIJ80X350-75S. It shares the same ISO 15552 interface, 80 mm bore, 350 mm stroke, 75 mm adjust window, G3/8 port, and mounting options, but adds an upgraded piston seal.
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 nominal 350 mm extend stroke can be shortened by up to 75 mm on-site, yielding a 275-350 mm usable range. The stop screw sets end position and is not a load lock.
