This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X225-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X225-30 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 SIJ80X225-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X225-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-30
The AirTAC SIJ80X225-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 225mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 195-225mm extension. It delivers 2513N push and 2268N pull force at 0.5 MPa, features a 25mm piston rod, M20x1.5 rod thread, and a fixed G3/8 port. The exact drop-in replacement is the SAIJ80X225-30, matching the interface, force, and mounting.
The SAIJ upgrade utilizes an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508N (60% of the 0.5MPa push force), translating to a 128kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet and cannot take a sensor. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X225-30 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAIJ80X225-30 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 SIJ80X225-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 195-225mm extend position on-site for inserting bearings without changing the entire cylinder setup.
Variable Length Diverter
Adjusts the extend stroke by up to 30mm to deflect varying package sizes on a line, ensuring precise routing without repositioning mounts.
Adjustable End Stop
Provides a mechanical end position that can be fine-tuned for different pallet heights, offering reliable physical stops for each load type.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-30 with the SAIJ80X225-30
To replace the discontinued SIJ80X225-30, order the drop-in SAIJ80X225-30, ensuring you retain the G3/8 port and M20x1.5 thread. For sizing both ways: the neighboring 63mm bore yields 1559N push at 0.5 MPa, while the 100mm bore yields 3927N. Choose the 30mm adjust window if your application needs field tuning between 195mm and 225mm. Mounting interfaces include FA, LB, and TC. Because this SKU has no -S suffix, it cannot accept a magnetic switch. For strokes at or above 300mm, carefully manage side-load to prevent premature seal wear. Remember the stop screw only sets end position; it does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-30
- ✓ 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 SIJ80X225-30 FAQ
Yes, the SIJ80X225-30 is discontinued. The exact drop-in replacement is the SAIJ80X225-30. It shares the same ISO 15552 interface, 80mm bore, 225mm stroke, 30mm adjust window, G3/8 port, and mounting options, but features an upgraded two Y-shaped one-way piston seal.
The double-acting single-rod cylinder delivers 2513N push and 2268N pull at 0.5 MPa, 3518N push at 0.7 MPa, and 4523N push at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 30mm adjust window, allowing the extend stroke to be shortened from the 225mm maximum down to 195mm on-site.
