This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X1000-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X1000-30S 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 SIJ80X1000-30S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-30S 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 SAIJ80X1000-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-30S
The AirTAC SIJ80X1000-30S 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 30 mm on-site, giving a usable range of 970-1000 mm. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. The exact drop-in replacement is the SAIJ80X1000-30S, matching the interface, force, and port.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift capacity with a 2:1 margin. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that the stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

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 SAIJ80X1000-30S 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 SIJ80X1000-30S Is Used
Length-Stop Diverter
Tuning the extend stroke by up to 30 mm on-site to hit a specific divert lane without re-engineering the fixed ISO 15552 mount.
Press Stroke Calibration
Adjusting the end position for a forming press where the exact material thickness requires slight 970-1000 mm stroke trimming.
Pallet Positioning Gate
Setting a precise physical stop for a pallet gate actuator, allowing 30 mm of field flexibility for varying pallet dimensions.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X1000-30S with the SAIJ80X1000-30S
To replace the discontinued SIJ80X1000-30S, order the drop-in SAIJ80X1000-30S, which retains the G3/8 port, 25 mm rod, and ISO 15552 mounting. For force sizing, this 80 mm bore yields 2513 N push at 0.5 MPa; the neighbouring 63 mm bore yields 1559 N, and the 100 mm bore yields 3927 N. The 30 mm adjust window is ideal for fine-tuning the extend end position without machining. Mounting options include Basic, FA, LB, and TC. The -S magnet supports legacy CS1-B/DS1-B switches. Because the stroke is 1000 mm, ensure external guides are used to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X1000-30S
- ✓ 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 SIJ80X1000-30S FAQ
Yes, the SIJ80X1000-30S is discontinued. The exact drop-in replacement is the SAIJ80X1000-30S. It shares the same ISO 15552 interface, 80 mm bore, 1000 mm stroke, 30 mm adjust window, G3/8 port, and mounting options. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
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. The theoretical max is 513 kgf at 1.0 MPa. The external stop screw allows you to trim the extend stroke by up to 30 mm on-site (usable range 970-1000 mm). The stop sets end position only; it is not a load lock.
