This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X450-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X450-10 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 SIJ80X450-10
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X450-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 450mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X450-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X450-10
The AirTAC SIJ80X450-10 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 10 mm on-site, giving a usable 440-450 mm window from the 450 mm nominal maximum. The 80 mm bore features 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 SAIJ80X450-10, sharing the same interface, force, and mounting.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot take a switch. The stop screw sets end position but is not a lock; for held loads use an external rod lock or SAIL/BSAI variant. On 450 mm strokes, use external guides to prevent rod bending.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X450-10 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 SAIJ80X450-10 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 SIJ80X450-10 Is Used
Press Fit Tuning
Final insertion of bearings where a 10 mm external stop trims the 450 mm extend stroke to dial in exact contact without reprogramming the motion controller.
End-of-Line Diverter
Actuating a routing gate where the physical stop sets the extended dwell position, allowing on-site adjustment for varying package profiles.
Pallet Stopper Gate
Regulating pallet flow by adjusting the extend end position up to 10 mm to accommodate pallet tolerance variations without changing the cylinder mount.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X450-10 with the SAIJ80X450-10
To replace the discontinued SIJ80X450-10, specify the drop-in SAIJ80X450-10, which retains the 80 mm bore, 450 mm stroke, 10 mm adjust window, G3/8 port, and ISO 15552 mounting. When sizing both ways, the neighbouring 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 10 mm adjust window for fine-tuning the extend end position within a 440-450 mm range. Mounting options include Basic, FA, LB, and TC brackets. This SKU lacks the -S magnet and cannot support legacy CS1-B/DS1-B sensors. Because the 450 mm stroke exceeds 300 mm, ensure external guides are used to manage side-load and prevent rod-bending. The stop screw is not a load lock; use a pilot-operated check valve or SAIL/BSAI variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X450-10
- ✓ 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 SIJ80X450-10 FAQ
Yes, the SIJ80X450-10 is discontinued. The exact drop-in replacement is the SAIJ80X450-10, which maintains the same ISO 15552 interface, 80 mm bore, 450 mm stroke, 10 mm adjust window, and G3/8 port.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw provides a 10 mm adjust window, allowing you to shorten the extend stroke from 450 mm down to 440 mm.
