This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X750-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X750-10 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 SIJ80X750-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X750-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 750mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X750-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X750-10
The AirTAC SIJ80X750-10 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 10 mm on-site, yielding a usable 740-750 mm window (750 mm is the maximum). This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, operating at 30-800 mm/s through a G3/8 port with 36 mm adjustable cushions. The stop sets end position only; it is not a lock.
The exact drop-in replacement is the SAIJ80X750-10, preserving the interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push), giving a 128 kg vertical lift with a 2:1 margin. Without live air the piston drifts; use an external rod lock or SAIL/BSAI for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X750-10 Is Used
Press Stroke Calibration
Needs field stroke tuning to dial in the exact 740-750 mm extend position for light assembly presses, using the external stop screw to compensate for tooling variations without re-plumbing.
Divertor Arm Positioning
Requires adjustable end-positioning to fine-tune the divertor arm reach on a conveyor line, ensuring precise product routing by trimming the extend stroke by up to 10 mm on-site.
Pallet Stopper Adjustment
Demands on-site stroke trimming to set the final stopper height for varying pallet sizes, using the 10 mm adjust window to secure exact alignment against the load.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X750-10 with the SAIJ80X750-10
To replace this discontinued SIJ80X750-10, order the drop-in SAIJ80X750-10, which retains the 10 mm adjust window, G3/8 port, and 36 mm cushions. When 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 10 mm adjust window if you need minor end-position tuning rather than a fixed stop. Mounting options include Basic, FA, LB, and TC. This SKU lacks a -S magnet and cannot take a magnetic switch. For the 750 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X750-10
- ✓ 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 SIJ80X750-10 FAQ
Yes, the SIJ80X750-10 is discontinued. The exact drop-in replacement is the SAIJ80X750-10, which shares the same ISO 15552 interface, 80 mm bore, 750 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The 80 mm bore provides 2513 N push and 2268 N pull @0.5 MPa, 3518 N push @0.7 MPa, and 4523 N push @0.9 MPa, with a theoretical max of 513 kgf @1.0 MPa. The external stop screw offers a 10 mm adjust window, allowing you to trim the extend stroke from 750 mm down to 740 mm. The stop sets end position only and is not a load lock.
