This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-30 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 SIJ80X175-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X175-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-30
The AirTAC SIJ80X175-30 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 30 mm on-site, yielding a usable 145-175 mm range from the 175 mm nominal maximum. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa. It features a 25 mm rod, M20x1.5 thread, and a G3/8 port.
The exact drop-in replacement is the SAIJ80X175-30, retaining the same interface, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), equating to a 128 kg vertical lift with a 2:1 margin. Note: this SKU lacks a magnet (-S) and cannot take a switch; the stop sets end position but is not a load lock.

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 SAIJ80X175-30 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 SIJ80X175-30 Is Used
Press Fit Tuning
Allows on-site extend stroke trimming by up to 30 mm to set precise pressing depths without machining hard stops.
Variable Diverter Gate
Adjusts the extend end position on-site to route different package sizes on a packaging line.
Adjustable End Stop
Sets a precise 145-175 mm extend position for pallets or fixtures requiring minor field adjustments.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-30 with the SAIJ80X175-30
To replace this discontinued SIJ80X175-30, order the drop-in SAIJ80X175-30, reusing your existing FA, LB, or TC ISO 15552 mounts. The 30 mm adjust window is ideal if your end position needs on-site tuning within 145-175 mm; if you need more trim, consider a larger window. For force sizing both ways: the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push at 0.5 MPa. Because this SKU has no -S magnet, it cannot accept a sensor; for sensing, select an SAIJ-S model. For strokes of 300 mm or more, verify side-load limits to prevent rod binding. The stop screw sets end position but does not hold loads on air loss; for held loads use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X175-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
