This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X75-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X75-30S 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 SIJ80X75-30S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 75mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X75-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-30S
The AirTAC SIJ80X75-30S 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 30 mm on-site, giving a usable extend range of 45-75 mm from the 75 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa via a G3/8 port. This stop screw strictly sets the end position; it is not a load lock.
The exact drop-in replacement is the SAIJ80X75-30S, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the safe working load is roughly 1508 N (about 60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X75-30S 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 SAIJ80X75-30S 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 SIJ80X75-30S Is Used
Adjustable End-Stop Pressing
Dial in the exact 45-75 mm extend contact position for light pressing tasks without re-engineering the entire fixture.
Variable Length Diverter
Tune the extend stroke on-site to deflect varying package sizes on a conveyor line using the 30 mm trim window.
Custom Position Ejector
Set precise ejection distances on packaging lines by adjusting the external stop screw to match product dimensions.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-30S with the SAIJ80X75-30S
To replace the discontinued SIJ80X75-30S, order the drop-in SAIJ80X75-30S, which keeps the exact 80 mm bore, 75 mm stroke, 30 mm adjust window, and G3/8 port. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. Choose the 30 mm adjust window if your application requires field tuning of the extend stroke within a 45-75 mm range. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the nominal 75 mm stroke is under 300 mm, side-load rod deflection is minimal. A plain cylinder does not hold loads on air loss; for held loads use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X75-30S
- ✓ 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 SIJ80X75-30S FAQ
Yes, the SIJ80X75-30S is discontinued. The exact drop-in replacement is the SAIJ80X75-30S, which shares the identical ISO 15552 interface, 80 mm bore, 75 mm stroke, 30 mm adjust window, and G3/8 port. The SAIJ upgrade uses an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, yielding a usable extend range of 45-75 mm. The stop sets end position only; it is not a load lock.
