This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1000-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1000-75 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 SIJ80X1000-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X1000-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-75
The AirTAC SIJ80X1000-75 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 1000 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 925-1000 mm window. This 80 mm bore uses a G3/8 port, a 25 mm rod, and delivers 2513 N push / 2268 N pull at 0.5 MPa. The SIJ line is discontinued; the exact drop-in replacement is the SAIJ80X1000-75, retaining the same interface, force, and adjust window.
The SAIJ successor benefits from an upgraded piston seal utilizing two Y-shaped one-way elements for low start-up pressure and long life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), translating to a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet and cannot take a switch. The stop screw sets end position but is not a load lock; use SAIL or an external rod lock for held loads.

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 SAIJ80X1000-75 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 SIJ80X1000-75 Is Used
Sorter Diverter Stroke Tuning
Field-tune the 925-1000 mm extend reach on a parcel conveyor diverter to accommodate varying lane widths without swapping the entire cylinder.
Variable-Depth Pallet Stop
Adjust the end position on-site by up to 75 mm to handle mixed pallet sizes in a storage lane, ensuring precise stopping without reprogramming.
Press Pin Insertion Depth
Dial in the exact insertion depth for different pin heights on an assembly line, using the external stop screw to set the final end position.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-75 with the SAIJ80X1000-75
To replace the discontinued SIJ80X1000-75, specify SAIJ80X1000-75 for an exact drop-in match. When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore provides 3927 N push at 0.5 MPa. Choose the 75 mm adjust window if you need on-site extend trimming between 925 and 1000 mm. Mounting options include Basic, FA, LB, and TC using the ISO 15552 interface. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. Finally, at 1000 mm stroke, mind side-load and rod-bending forces; use external guides to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-75
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
