This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X350-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X350-100S 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 SIJ80X350-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X350-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100S
The AirTAC SIJ80X350-100S 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 100 mm on-site, giving a usable 250-350 mm window from the 350 mm nominal maximum. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa (4523 N push at 0.9 MPa).
The exact drop-in replacement is the SAIJ80X350-100S, retaining the same ISO 15552 mounting interface, bore, and force. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements 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), translating 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.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X350-100S 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 SAIJ80X350-100S 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 SIJ80X350-100S Is Used
Variable Stroke Pressing
Allows operators to dial in the exact 250-350 mm extend position for pressing bearings without machining custom spacers.
Adjustable Diverter Arm
Tunes the extend reach on-site to accommodate different package widths on a sorting line without swapping cylinders.
End-Position Calibration
Provides a 100 mm trim window to precisely set the end stop for stacking fixtures that require periodic recalibration.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-100S with the SAIJ80X350-100S
To replace the discontinued SIJ80X350-100S, order the drop-in SAIJ80X350-100S, which preserves the G3/8 port, M20x1.5 thread, and FA/LB/TC mountings. 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 the -100 adjust window if your fixture needs on-site extend tuning between 250 and 350 mm. The -S suffix confirms a built-in piston magnet for legacy CS1-B/DS1-B switches. Because the 350 mm stroke exceeds 300 mm, verify side-load limits and use external guides to prevent rod bending. The stop screw sets end position but does not hold loads on air loss; for load holding use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X350-100S
- ✓ 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 SIJ80X350-100S FAQ
Yes, the SIJ80X350-100S is discontinued. The exact drop-in replacement is the SAIJ80X350-100S. It shares the same ISO 15552 interface, 80 mm bore, 350 mm nominal stroke, 100 mm adjust window, G3/8 port, and mounting options, but features 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 (max 513 kgf at 1.0 MPa). The external stop screw provides a 100 mm adjust window, allowing you to shorten the extend stroke on-site from the 350 mm maximum down to 250 mm. This stop sets the end position and is not a load lock.
