This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-75 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 SIJ80X160-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X160-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75
The AirTAC SIJ80X160-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 160 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable forward travel of 85 to 160 mm. The G3/8 port and 36 mm adjustable cushions manage kinetic energy, delivering 2513 N push and 2268 N pull at 0.5 MPa. As this SIJ is end-of-life, the exact drop-in replacement is the SAIJ80X160-75, retaining the same interface, force, and adjust window.
The SAIJ successor features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. Because the stop screw only sets the end position, it is not a load lock; use an external rod lock or pilot-operated check valve for held loads. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), equating to a 128 kg vertical lift with a 2:1 margin. This non-magnetic SKU cannot take a switch.

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 SAIJ80X160-75 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 SIJ80X160-75 Is Used
Variable Pitch Forming
Bending stations that need to alter the extend depth by up to 75 mm for different material thicknesses without swapping the entire actuator.
Adjustable Transfer Stops
Diverting packages of varying sizes on a line by tuning the extend stroke on-site between 85 and 160 mm to act as a physical barrier.
Tiered Pallet Positioning
Pressing or locating pallets at distinct heights where the final lower position must be precisely dialed in via the external stop screw.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75 with the SAIJ80X160-75
To replace the discontinued SIJ80X160-75, order the SAIJ80X160-75 drop-in, keeping the same FA, LB, or TC ISO 15552 mounts and G3/8 port. Size both ways: the 63 mm neighbor yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N. Select the 75 mm adjust window if your fixture requires trimming the 160 mm nominal extend down to a minimum of 85 mm. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; confirm if position feedback is required. For strokes of 300 mm or longer, carefully manage side-load guiding to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-75
- ✓ 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 SIJ80X160-75 FAQ
Yes, the SIJ80X160-75 is discontinued. The exact drop-in replacement is the SAIJ80X160-75, which shares the identical ISO 15552 mounting interface, 80 mm bore, 160 mm stroke, 75 mm adjust window, and G3/8 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
It delivers 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 theoretical max is 513 kgf at 1.0 MPa. The external stop screw provides a 75 mm adjustment window, allowing you to shorten the 160 mm extend stroke down to 85 mm on-site. The stop sets end position only; it is not a load lock.
