This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X900-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X900-75S 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 SIJ80X900-75S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 900mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X900-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75S
The AirTAC SIJ80X900-75S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ80X900-75S. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 825-900 mm range from the 900 mm nominal maximum. The G3/8 port and 25 mm rod deliver 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa. The SAIJ drop-in retains the exact ISO 15552 mounting interface, bore, and force.
The SAIJ replacement adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; the cylinder drifts on air loss. For safe sizing, expect a working load around 1508 N (60% of the 0.5 MPa push) or a 128 kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

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 SAIJ80X900-75S 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 SIJ80X900-75S Is Used
Variable Stroke Pressing
Dialing in the exact 825-900 mm extend position on-site for pressing assemblies without machining custom spacers.
Adjustable Transfer Diverter
Tuning the extend stop to accommodate different package widths on a sorting line within the 75 mm window.
Variable Depth Palletizing
Adjusting the extend endpoint to handle varying pallet load depths while utilizing the full 900 mm stroke.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75S with the SAIJ80X900-75S
To replace the discontinued SIJ80X900-75S, order the drop-in SAIJ80X900-75S, which preserves the G3/8 port, 25 mm rod, 36 mm cushions, and 75 mm adjust window. 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 75 mm adjust window if you need on-site extend trimming between 825 and 900 mm; for fixed stops, a standard SAI cylinder is simpler. Mounting options include FA, LB, and TC brackets. The -S magnet supports legacy CS1-B/DS1-B sensors. For this 900 mm long stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X900-75S
- ✓ 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 SIJ80X900-75S FAQ
Yes, the SIJ80X900-75S is discontinued. The exact drop-in replacement is the SAIJ80X900-75S. It shares the identical ISO 15552 interface, 80 mm bore, 900 mm stroke, 75 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa. The external stop screw allows trimming the extend stroke by up to 75 mm on-site, giving a usable range of 825-900 mm. Note the stop sets end position and is not a load lock.
