This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X80-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X80-75 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 SIJ80X80-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X80-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-75
The AirTAC SIJ80X80-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and G3/8 port. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 5-80 mm extend window from the 80 mm nominal maximum. The stop sets the end position but is not a load lock. This SKU has no -S magnet and cannot take a switch.
This SIJ model is discontinued; the exact drop-in replacement is the SAIJ80X80-75, matching the ISO 15552 interface, bore, force, and mountings. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Force is 2513 N push and 2268 N pull @0.5 MPa. Computed insight: safe working load is ~1508 N (60% of push @0.5 MPa) and vertical lift is ~128 kg with a 2:1 margin. No load holding without live air; use SAIL or BSAI for locks.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X80-75 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 SAIJ80X80-75 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 SIJ80X80-75 Is Used
Crimping Station Setup
Dial in the exact 40 mm extend contact point on varying harness sizes by trimming the 80 mm nominal stroke on-site without swapping cylinders.
Variable Package Divert
Adjust the extend stop on the fly to push different carton widths onto a sorting lane, using the 5-80 mm window to match product dimensions.
Pallet Positioning Stop
Fine-tune the physical end-stop height for mixed pallet loads, relying on the 2513 N push force at 0.5 MPa to halt the load securely.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X80-75 with the SAIJ80X80-75
To replace the discontinued SIJ80X80-75, order the drop-in SAIJ80X80-75, reusing your FA, LB, or TC ISO 15552 mounts. The 75 mm adjust window lets you tune the extend end-point precisely. If sizing both ways, the 63 mm neighbor gives 1559 N push @0.5 MPa, while the 100 mm bore yields 3927 N. For strokes >=300 mm, verify side-load limits. This non-magnetic SKU cannot take legacy CS1-B/DS1-B sensors. Because the stop screw is not a lock, add an external rod lock for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X80-75
- ✓ 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 SIJ80X80-75 FAQ
Yes, the SIJ80X80-75 is discontinued. The exact drop-in replacement is the SAIJ80X80-75, which shares the same ISO 15552 interface, 80 mm bore, 80 mm stroke, 75 mm adjust window, G3/8 port, and mountings. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The double-acting single-rod 80 mm bore delivers 2513 N push and 2268 N pull @0.5 MPa, 3518 N push @0.7 MPa, and 4523 N push @0.9 MPa (max 513 kgf @1.0 MPa). The external stop screw provides a 75 mm adjust window, shortening the extend stroke from the 80 mm nominal max down to 5 mm. The stop sets end position only; it is not a load lock, and the cylinder drifts on air loss.
