This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-30 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 SIJ80X150-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 150mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X150-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30
The AirTAC SIJ80X150-30 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable 120-150 mm stroke. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. The direct drop-in replacement is the SAIJ80X150-30, matching the interface, force, and mounting.
Force output is 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. A computed buyer insight: the safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure. The stop sets end position but is not a load lock; use SAIL or BSAI for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X150-30 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 SAIJ80X150-30 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 SIJ80X150-30 Is Used
Press Fit Tuning
Allows operators to dial in the exact 120-150 mm extend position for pressing bearings without machining hard stops.
Transfer Diverter
Adjusts the extend stroke on-site to accommodate varying package sizes on a sorting line.
Pallet Stopper
Fine-tunes the stopping height for different pallet loads before the stretch wrapper cycle begins.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-30 with the SAIJ80X150-30
To replace the discontinued SIJ80X150-30, order the drop-in SAIJ80X150-30. For sizing both ways, the neighboring bores are 63 mm (2182 N push @0.7 MPa) and 100 mm (5497 N push @0.7 MPa). The 30 mm adjust window is ideal for fine-tuning the extend end position within the 120-150 mm range. Mounting options include FA, LB, and TC. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch. For strokes >=300 mm, verify side-load limits. The stop screw sets position only; it does not lock, so add an external rod lock for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X150-30
- ✓ 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 SIJ80X150-30 FAQ
Yes, the SIJ80X150-30 is discontinued. The exact drop-in replacement is the SAIJ80X150-30. It shares the same ISO 15552 interface, 80 mm bore, 150 mm stroke, G3/8 port, and 30 mm adjust window.
