This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X125-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X125-30 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 SIJ80X125-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X125-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 125mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X125-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X125-30
The AirTAC SIJ80X125-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 125 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 95-125 mm extension window. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, features a 25 mm rod, M20x1.5 rod thread, and a fixed G3/8 port. The exact drop-in replacement is the SAIJ80X125-30, matching the interface, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions for direct reuse of FA, LB, and TC brackets, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Because this SKU lacks a -S magnet, it cannot accept a magnetic switch. The stop screw sets the end position but is not a load lock; for held loads use an external rod lock or pilot-operated check valve. Computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push), allowing a vertical lift of about 128 kg with a 2:1 margin.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X125-30 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 SAIJ80X125-30 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 SIJ80X125-30 Is Used
Press Fit Tuning
Adjusting the extend stroke on-site by up to 30 mm allows precise press-fit depth control for 80 mm bore assemblies without changing the cylinder body.
Transfer Diverter
Field-tuning the 95-125 mm extend window lets operators set the exact diverter gate position for varying product widths on the line.
Carton Forming Stop
The external stop screw provides a rigid mechanical end position for carton folding arms, easily tweaked when pack sizes change.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X125-30 with the SAIJ80X125-30
To replace the discontinued SIJ80X125-30, order the SAIJ80X125-30 drop-in; it preserves the G3/8 port, 36 mm adjustable cushion, and 30 mm stroke-trim window (95-125 mm extend). When sizing both ways, the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N—choose based on your exact force requirement. Select FA, LB, or TC mounting per your ISO 15552 interface. This non-magnetic SKU cannot take a switch; for sensing you need a -S model. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. Remember the stop screw only sets end position and does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X125-30
- ✓ 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 SIJ80X125-30 FAQ
Yes, the AirTAC SIJ80X125-30 is discontinued. The exact drop-in replacement is the SAIJ80X125-30. It shares the same ISO 15552 interface, 80 mm bore, 125 mm stroke, 30 mm adjust window, G3/8 port, and mounting options. The SAIJ also features an upgraded 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 at 0.9 MPa (max 513 kgf at 1.0 MPa). The external stop screw window is 30 mm, allowing a usable extend stroke of 95-125 mm. The stop sets end position only; it is not a load lock.
