This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X800-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X800-30 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 SIJ80X800-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X800-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30
The AirTAC SIJ80X800-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 800 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 770 to 800 mm window. The 80 mm bore uses a G3/8 port, a 25 mm rod, and 36 mm adjustable cushions. Force matches the standard single-rod SAI: 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. The direct drop-in replacement is the SAIJ80X800-30, sharing the exact interface, force, and adjust window.
Because this SKU lacks a -S magnet, it cannot take a magnetic switch. The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Computed buyer insight: safe working load is roughly 1508 N (60% of the 0.5 MPa push), giving a 128 kg vertical lift capacity with a 2:1 margin. At 800 mm, add external guides to prevent rod bending.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X800-30 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 SAIJ80X800-30 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 SIJ80X800-30 Is Used
Transfer Line Diverter
Field-tunes the 770-800 mm extend stroke to match varying pallet lengths on a conveyor without swapping the cylinder.
Adjustable Pressing Station
Trims the extend stop by up to 30 mm on-site to set precise material contact depth for changing product profiles.
Variable-Height Lift Gate
Sets the exact extend endpoint for different package sizes, relying on external guides to support the long 800 mm rod.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30 with the SAIJ80X800-30
To replace the discontinued SIJ80X800-30, order the drop-in SAIJ80X800-30, reusing your existing ISO 15552 FA, LB, or TC mounts. The 30 mm adjust window gives a 770-800 mm extend stroke; choose a smaller window if you need finer end-position tuning. If sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa. This non-magnetic SKU cannot fit legacy CS1-B/DS1-B sensors. For the 800 mm stroke, strictly use external guides to manage side-load and rod-bending risks. The stop screw sets end position only; it is not a lock, so add a pilot-operated check valve for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X800-30
- ✓ 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 SIJ80X800-30 FAQ
Yes, the SIJ80X800-30 is discontinued. The exact drop-in replacement is the SAIJ80X800-30. It shares the same ISO 15552 interface, 80 mm bore, 800 mm stroke, 30 mm adjust window, G3/8 port, and mounting options, but adds an upgraded two Y-shaped one-way 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 push at 0.9 MPa, with a theoretical max of 513 kgf. The external stop screw window is 30 mm, allowing you to trim the extend stroke from 800 mm down to 770 mm on-site. The stop sets end position and is not a load lock.
