This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X900-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X900-10 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 SIJ80X900-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 900mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X900-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10
The AirTAC SIJ80X900-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 900 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable range of 890-900 mm. This stop sets the end position; it is not a load lock. The 80 mm bore uses a G3/8 port, a Ø25 mm rod, and 36 mm adjustable cushions, delivering 2513 N push and 2268 N pull at 0.5 MPa.
This SKU is end-of-life and drops directly into the SAIJ80X900-10 replacement, which retains the exact interface, force, and mounting. The SAIJ upgrade features a two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, the 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. This non-magnetic model cannot take a switch; for load holding without live air, use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X900-10 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 SAIJ80X900-10 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 SIJ80X900-10 Is Used
Long-Reach Push Trim
Fine-tune the 890-900 mm extend end position on a 900 mm stroke actuator to dial in exact contact without re-engineering the entire ISO 15552 fixture.
Extended Forming Stop
Set a precise 10 mm on-site stroke adjustment for a long-throw press operation, using the external stop to set the final end position accurately.
Transfer Length Calibration
Adjust the extend stroke at the end of a 900 mm transfer line to accommodate minor part length variations while using the 80 mm bore's 2513 N push force.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-10 with the SAIJ80X900-10
To replace the SIJ80X900-10, order the drop-in SAIJ80X900-10, matching the 80 mm bore, 900 mm stroke, 10 mm adjust window, and G3/8 port. 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. Select your adjust window based on the exact on-site extend trim needed (here, 890-900 mm). Mounting interfaces include Basic, FA, LB, and TC. Because this is a non-magnetic SKU (no -S suffix), it cannot accept a sensor. For the 900 mm long stroke, use external guides to prevent rod bending and manage side loads. Remember, the stop screw sets position but does not lock the load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X900-10
- ✓ 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 SIJ80X900-10 FAQ
Yes, the SIJ80X900-10 is discontinued. The exact drop-in replacement is the SAIJ80X900-10. It shares the identical ISO 15552 interface, 80 mm bore, 900 mm stroke, 10 mm adjust window, G3/8 port, and mounting options, but adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life.
The 80 mm bore delivers 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 provides a 10 mm trim window, making the usable extend stroke 890-900 mm. The stop sets end position and is not a load lock; use an external rod lock for load holding.
