This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-75 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 SIJ80X600-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X600-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75
The AirTAC SIJ80X600-75 is a discontinued double-acting single-rod adjustable-stroke ISO 15552 cylinder with a 600 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable range of 525-600 mm. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, features a 25 mm rod, M20x1.5 thread, G3/8 port, and 36 mm adjustable cushions. The exact drop-in replacement is the SAIJ80X600-75, retaining the same interface, force, and adjust window.
The SAIJ upgrade utilizes an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 2513 N push @0.5 MPa), translating to a 128 kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot accept a switch. The stop screw sets end position but is not a load lock; use 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 SAIJ80X600-75 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 SIJ80X600-75 Is Used
Variable Position Pressing
Allows on-site stroke trimming up to 75 mm to dial in exact contact positions for pressing assemblies without machining custom spacers.
Adjustable Diverter Arms
Tunes the extend endpoint on packaging lines to handle varying product widths, ensuring precise routing on the fly.
Variable Depth Stops
Sets custom material push-off distances in material handling systems, accommodating different pallet depths via the external stop screw.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75 with the SAIJ80X600-75
To replace the discontinued SIJ80X600-75, order the drop-in SAIJ80X600-75, matching the 80 mm bore, 600 mm max stroke, 75 mm adjust window, and G3/8 port. For sizing both ways: the neighboring 63 mm bore yields 1559 N push @0.5 MPa, while the 100 mm bore yields 3927 N push @0.5 MPa. Choose the 75 mm adjust window if your extend stroke needs on-site tuning between 525-600 mm. Mounting interfaces (FA, LB, TC) reuse existing ISO 15552 brackets. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For the 600 mm stroke, ensure external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-75
- ✓ 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 SIJ80X600-75 FAQ
Yes, the SIJ80X600-75 is discontinued. The exact drop-in replacement is the SAIJ80X600-75, offering the same ISO 15552 interface, 600 mm stroke, 75 mm adjust window, and mounting compatibility.
The 80 mm bore provides 2513 N push and 2268 N pull @0.5 MPa, 3518 N @0.7 MPa, and 4523 N @0.9 MPa (max 513 kgf @1.0 MPa). The external stop screw provides a 75 mm adjust window, allowing the extend stroke to be shortened from 600 mm down to 525 mm. It uses a G3/8 port.
