This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X160-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X160-100 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 SIJ80X160-100
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X160-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100
The AirTAC SIJ80X160-100 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 100 mm on-site, giving a usable 60-160 mm extend range from the 160 mm nominal maximum. At 0.5 MPa this 80 mm bore delivers 2513 N push and 2268 N pull force, scaling to 4523 N push at 0.9 MPa. It features a Ø25 mm rod, M20x1.5 rod thread, and a fixed G3/8 port.
Because the SIJ line is end-of-life, the exact drop-in replacement is the SAIJ80X160-100, retaining the same interface, bore, force, and mounting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal 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), equating to a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet and cannot take a sensor; the stop screw sets end position but is not a load lock.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100 Is Used
Variable Press Tooling
Trimming the extend stroke by up to 100 mm on-site allows operators to adapt pressing depth for varying material thicknesses without swapping the entire actuator.
Adjustable Diverters
Tuning the extend stroke from 160 mm down to 60 mm accommodates changing package sizes on a packaging line, ensuring precise physical diverting contact.
Variable Height Stops
Field-adjusting the end position provides flexible physical stops for pallets of different heights, where the 2513 N push force at 0.5 MPa handles robust halting.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100 with the SAIJ80X160-100
To replace the discontinued SIJ80X160-100, order the SAIJ80X160-100 directly—it is a true drop-in swap sharing the ISO 15552 dimensions, G3/8 port, and 100 mm adjust window. When 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. Choose the 100 mm adjust window if your extend stroke needs on-site tuning between 60 and 160 mm. Mounting options include FA, LB, and TC brackets. Because this SKU has no -S magnet, it cannot accept a magnetic switch; add external sensing if needed. For strokes of 300 mm or longer, carefully manage side loads to prevent excessive guide wear. The external stop sets the end position but does not lock the load—use an external rod lock or check valve for hold.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-100
- ✓ 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 SIJ80X160-100 FAQ
Yes, the SIJ80X160-100 is discontinued. The exact drop-in replacement is the SAIJ80X160-100, which shares the identical ISO 15552 interface, 80 mm bore, 160 mm stroke, 100 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
This 80 mm bore cylinder has a G3/8 port and provides 2513 N push / 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa. The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from the 160 mm nominal maximum down to 60 mm. The stop sets end position but is not a load lock.
