This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X350-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X350-10 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 SIJ80X350-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X350-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-10
The AirTAC SIJ80X350-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 350 mm nominal stroke and G3/8 port. The external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 340-350 mm window. This 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, rising to 3518 N at 0.7 MPa. The exact drop-in replacement is the SAIJ80X350-10, matching the interface, force, and mounting.
The SAIJ successor retains the ISO 15552 mounting dimensions for direct reuse and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Computed buyer insight: 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. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position only—it is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X350-10 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 SAIJ80X350-10 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 SIJ80X350-10 Is Used
Press Fit Tuning
Final press depth requires exact 340-350 mm endpoint tuning to seat bearings without bottoming out the tooling.
Transfer Stopper
Adjusting the extend stop by up to 10 mm accommodates varying package widths on a single pneumatic transfer line.
Carton Flap Folding
Fine-tuning the extend stroke ensures precise flap contact on varying box heights before sealing.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X350-10 with the SAIJ80X350-10
To replace the discontinued SIJ80X350-10, order the drop-in SAIJ80X350-10. 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. This 80 mm model provides 2513 N push at 0.5 MPa and 4523 N at 0.9 MPa. Choose the 10 mm adjust window if you need 340-350 mm end-position tuning; for larger trims, select a different adjust suffix. Mounting options include FA, LB, and TC. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For the 350 mm stroke, use external guides to prevent rod bending and manage side loads. The stop screw is not a lock; for load holding on air loss, use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X350-10
- ✓ 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 SIJ80X350-10 FAQ
Yes, the SIJ80X350-10 is discontinued. The exact drop-in replacement is the SAIJ80X350-10, which shares the same ISO 15552 interface, 350 mm stroke, 10 mm adjust window, G3/8 port, and mounting.
The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N at 0.9 MPa, and 513 kgf max at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing you to trim the extend stroke from 350 mm down to 340 mm on-site.
