This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1000-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1000-30 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 SIJ80X1000-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X1000-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-30
The AirTAC SIJ80X1000-30 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ80X1000-30. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable stroke of 970-1000 mm. The 80 mm bore uses a G3/8 port, a 25 mm rod, and delivers 2513 N push / 2268 N pull at 0.5 MPa. The SAIJ drop-in keeps the exact mounting interface, force, and adjust window.
The replacement SAIJ family adds an upgraded two-piece Y-shaped piston seal for low start-up pressure and long life. For sizing, the safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), translating to a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet (-S) and cannot take a switch. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X1000-30 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 SAIJ80X1000-30 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 SIJ80X1000-30 Is Used
Press Tonnage Calibration
Needs field stroke tuning to dial in the exact 970-1000 mm extend endpoint during press setup, preventing over-travel without swapping cylinders.
Variable-Length Diverter
Requires trimming the extend stroke by up to 30 mm on-site to adjust a diverter arm for changing package sizes on the fly.
Adjustable End-Stop Pusher
Demands a precise physical stop at variable product lengths, using the external screw to set the final resting position securely.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-30 with the SAIJ80X1000-30
To replace the SIJ80X1000-30, order the drop-in SAIJ80X1000-30, which preserves the 1000 mm max stroke, 30 mm adjust window, G3/8 port, and ISO 15552 mounting. If sizing both ways, the 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N push at 0.5 MPa. Choose the 30 mm adjust window if you need on-site extend tuning between 970 and 1000 mm. Mounting options include Basic, FA, LB, and TC. Because this SKU has no -S magnet, it cannot accept a sensor. At 1000 mm stroke, prevent rod bending by using external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-30
- ✓ 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 SIJ80X1000-30 FAQ
Yes, the SIJ80X1000-30 is discontinued. The exact drop-in replacement is the SAIJ80X1000-30, offering the same ISO 15552 interface, 80 mm bore, 1000 mm max stroke, 30 mm adjust window, G3/8 port, and 2513 N push force at 0.5 MPa.
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, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw window is 30 mm, allowing you to shorten the 1000 mm extend stroke down to 970 mm on-site. The stop sets end position only and is not a load lock.
