This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-50 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-50 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 SIJ80X600-50
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-50 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 SAIJ80X600-50, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-50
The AirTAC SIJ80X600-50 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 50 mm on-site, giving a usable 550-600 mm stroke. The nominal 600 mm is the maximum. Bore 80 mm delivers 2513 N push and 2268 N pull at 0.5 MPa, with a G3/8 port and M20x1.5 rod thread.
The exact drop-in replacement is the SAIJ80X600-50, matching the interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. Computed buyer insight: safe working load is ~1508 N (60% of the 0.5 MPa push), yielding a ~128 kg vertical lift with a 2:1 margin. The stop sets end position but is not a lock; use SAIL or BSAI 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 SAIJ80X600-50 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 SIJ80X600-50 Is Used
Variable-depth machining stops
Trimming the 600 mm extend stroke by up to 50 mm on-site allows a single cylinder to feed parts to multiple machining depths without changing the entire actuator setup.
Adjustable transfer pushers
When conveyor lane widths or product lengths fluctuate, the external stop screw provides a fast mechanical tuning window to reposition the pusher end point accurately.
Packaging flap folding
Carton sealing equipment benefits from the 550-600 mm usable stroke window, enabling operators to dial in the exact fold position for varying box heights on the fly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-50 with the SAIJ80X600-50
To replace the discontinued SIJ80X600-50, order the drop-in SAIJ80X600-50. For sizing both ways: the 63 mm bore gives 1559 N push, and the 100 mm bore gives 3927 N push at 0.5 MPa. The 50 mm adjust window is ideal if your end-position varies by up to 50 mm; for larger changes, pick a different nominal stroke. Mounting interfaces (FA, LB, TC) reuse ISO 15552 dimensions. This SKU lacks the -S magnet and cannot take a switch. For the 600 mm stroke, support the rod to prevent bending and side-load damage. The stop screw sets position, not a lock; for load holding on air loss, use an external rod lock or check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-50
- ✓ 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 SIJ80X600-50 FAQ
Yes, the SIJ80X600-50 is discontinued. The exact drop-in replacement is the SAIJ80X600-50. It shares the same ISO 15552 interface, 80 mm bore, 600 mm stroke, 50 mm adjust window, G3/8 port, and mounting options, while adding an upgraded SAI piston seal.
The 80 mm bore provides 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 external stop screw allows you to trim the extend stroke by up to 50 mm on-site, yielding a usable 550-600 mm stroke. The stop sets end position only; it is not a load lock.
