This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X225-100S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X225-100S 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 SIJ80X225-100S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X225-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-100S
The AirTAC SIJ80X225-100S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the drop-in SAIJ80X225-100S. It features an external stop screw that lets you trim the extend stroke by up to 100 mm on-site, giving a usable 125-225 mm window from the 225 mm maximum. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, with a G3/8 port and 36 mm adjustable cushions.
The SAIJ upgrade retains the exact interface but uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Reusing existing ISO 15552 mounting saves retrofit cost. 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. The stop screw sets the 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 SAIJ80X225-100S 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 SAIJ80X225-100S 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 SIJ80X225-100S Is Used
Variable Depth Drilling
Adjust the 100 mm extend window on-site to tune drilling depth for different material thicknesses without swapping the entire actuator.
Multi-Format Diverter
Trim the extend stroke dynamically to deflect varying package sizes on a single line, ensuring positive contact without overtravel.
Adjustable Pusher Stops
Set precise end positions for palletizing or sorting tasks where physical stop locations must be reconfigured for changing product runs.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-100S with the SAIJ80X225-100S
To replace the discontinued SIJ80X225-100S, use the SAIJ80X225-100S drop-in, keeping the 225 mm nominal stroke, 100 mm adjust window, G3/8 port, and M20x1.5 rod thread. When sizing both ways, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. This 80 mm bore provides 2518 N push at 0.5 MPa and 3518 N at 0.7 MPa. Choose FA, LB, or TC mounts to match your ISO 15552 footprint. The -S suffix means a piston magnet is present for CS1-B/DS1-B sensors. For strokes >=300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-100S
- ✓ 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 SIJ80X225-100S FAQ
Yes, the SIJ80X225-100S is discontinued. The exact drop-in replacement is the SAIJ80X225-100S. It shares the same ISO 15552 interface, 80 mm bore, 225 mm stroke, 100 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal.
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 at 0.9 MPa, with a 513 kgf max at 1.0 MPa. The external stop screw allows trimming the extend stroke by up to 100 mm on-site (usable 125-225 mm). Note the stop sets end position and is not a load lock.
