This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X130-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X130-50S 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 SIJ80X130-50S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-50S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X130-50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-50S
The AirTAC SIJ80X130-50S 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 50 mm on-site, giving a usable 80-130 mm window from the 130 mm nominal maximum. The stop sets the end position but is not a load lock. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, features a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions.
The exact drop-in replacement is the SAIJ80X130-50S, sharing the same ISO 15552 interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. A computed buyer insight: safe working load is ~1508 N (60% of the 2513 N push @0.5 MPa), yielding a ~128 kg vertical lift with a 2:1 margin. The -S suffix means a piston magnet is present for CS1-B/DS1-B switches.

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 SAIJ80X130-50S 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 SIJ80X130-50S Is Used
Press Fit Tuning
Allows operators to dial in the exact 80-130 mm extend position for pressing bearings without machining custom spacers.
Variable Length Diverter
Adjusts the extend stroke on-site to deflect varying package sizes on a line, ensuring positive contact without repositioning the cylinder.
Adjustable End Stop
Sets a precise mechanical end position for forming folds, easily trimmed by up to 50 mm when pack dimensions change.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X130-50S with the SAIJ80X130-50S
To replace the discontinued SIJ80X130-50S, order the drop-in SAIJ80X130-50S. To size both ways, the neighbouring 63 mm bore yields 2182 N push @0.7 MPa, while the 100 mm bore yields 5497 N push @0.7 MPa. Choose the 50 mm adjust window when you need on-site extend trimming between 80 and 130 mm. Reuse FA, LB, or TC mounts via the ISO 15552 interface. The -S magnet enables legacy CS1-B/DS1-B sensors. For strokes >=300 mm, verify side-load guidance. The stop screw is not a lock; for load holding without live air, use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X130-50S
- ✓ 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 SIJ80X130-50S FAQ
Yes, the SIJ80X130-50S is discontinued. The exact drop-in replacement is the SAIJ80X130-50S. It shares the same ISO 15552 interface, 80 mm bore, 130 mm stroke, 50 mm adjust window, G3/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The 80 mm bore provides 2513 N push and 2268 N pull @0.5 MPa, 3518 N push @0.7 MPa, 4523 N push @0.9 MPa, and a 513 kgf max @1.0 MPa. The external stop screw provides a 50 mm adjust window, shortening the extend stroke from the 130 mm maximum down to 80 mm. The stop sets end position only; it is not a load lock.
