This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X150-75FA — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X150-75FA 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 SIJ80X150-75FA
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-75FA 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 SAIJ80X150-75FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-75FA
The AirTAC SIJ80X150-75FA 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 75 mm on-site, yielding a usable 75-150 mm range from the 150 mm nominal maximum. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa via its G3/8 port, with a 36 mm adjustable air cushion at each end. The exact drop-in replacement is the SAIJ80X150-75FA, retaining the same interface, FA mounting, and force.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This SKU lacks a -S magnet and cannot take a magnetic switch. 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 the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SAIJ80X150-75FA 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 SIJ80X150-75FA Is Used
Variable Depth Forming Press
An 80 mm bore press trimming the extend stroke by up to 75 mm on-site to dial in precise material forming depths without machining custom spacers.
Adjustable Transfer Diverter
A package handling diverter requiring field stroke tuning between 75 and 150 mm to accommodate varying box sizes on the ISO 15552 FA mount.
Modular Shelving Insertion
An assembly station pushing inserts into shelving bays, using the 2513 N push force at 0.5 MPa and adjusting the stop screw for different shelf depths.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X150-75FA with the SAIJ80X150-75FA
To replace the discontinued SIJ80X150-75FA, order the drop-in SAIJ80X150-75FA, matching the 80 mm bore, 150 mm nominal stroke, 75 mm adjust window, and FA foot mounting. Size both ways using 0.5 MPa forces: the 63 mm bore offers 1559 N push / 1402 N pull, while the 100 mm bore provides 3927 N push / 3681 N pull. The 75 mm adjust window is ideal if your extend stroke needs on-site tuning between 75 and 150 mm. Because this non-magnetic SKU lacks a -S suffix, it cannot accept legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, carefully manage side loads to prevent excessive guide wear. Remember the external stop sets end position but provides no load holding on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X150-75FA
- ✓ 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 SIJ80X150-75FA FAQ
Yes, the AirTAC SIJ80X150-75FA is discontinued. The exact drop-in replacement is the SAIJ80X150-75FA. It shares the identical ISO 15552 interface, 80 mm bore, 150 mm stroke, 75 mm adjust window, G3/8 port, and FA mounting. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
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 push at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw window is 75 mm, allowing you to shorten the 150 mm nominal extend stroke down to 75 mm on-site. The stop sets end position only and is not a load lock.
