This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X500-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X500-30 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 SIJ80X500-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X500-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30
The AirTAC SIJ80X500-30 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, yielding a usable 470-500 mm window from the 500 mm nominal maximum. The 80 mm bore uses a G3/8 port, a 25 mm rod, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa.
This SKU is end-of-life; the exact drop-in replacement is the SAIJ80X500-30, which retains the ISO 15552 mounting interface, bore, and force. The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push force), translating to a 128 kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X500-30 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 SAIJ80X500-30 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 SIJ80X500-30 Is Used
Press Tonnage Calibration
Needs field stroke tuning to set precise 470-500 mm extend endpoints during press tooling setup, using the external stop screw to dial in the exact contact depth without re-mounting the actuator.
Variable-Length Diverter
Requires on-site stroke trimming to alter the extend reach by up to 30 mm, accommodating different package widths on a sorting line while maintaining the 2513 N push force needed to actuate the diverter arms.
Adjustable Stop Positioning
Demands an adjustable end-position stop to tune the extend stroke within the 470-500 mm window, allowing operators to reconfigure pallet stacking heights quickly without changing out the entire cylinder assembly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-30 with the SAIJ80X500-30
To replace the discontinued SIJ80X500-30, order the drop-in SAIJ80X500-30, ensuring you keep the -30 adjust window to maintain your 470-500 mm extend trim capability. 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 80 mm bore for its 2513 N push if that matches your 1508 N safe load target. Mounting reuse is guaranteed via the ISO 15552 interface using FA, LB, or TC brackets. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch for position sensing. Finally, at 500 mm stroke, account for side-load and rod-bending forces by incorporating external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X500-30
- ✓ 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 SIJ80X500-30 FAQ
Yes, the AirTAC SIJ80X500-30 is discontinued. The exact drop-in replacement is the SAIJ80X500-30. It shares the identical ISO 15552 interface, 80 mm bore, 500 mm stroke, 30 mm adjust window, G3/8 port, and 4523 N push force at 0.9 MPa, but adds an upgraded two-piece Y-shaped piston seal for 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 513 kgf max at 1.0 MPa. The external stop screw provides a 30 mm adjust window, meaning the usable extend stroke is 470-500 mm. The stop sets the end position but is not a load lock; for load holding on air loss, use an external rod lock or SAIL variant.
