This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-100 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 SIJ80X200-100
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X200-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100
The AirTAC SIJ80X200-100 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The exact drop-in replacement is the SAIJ80X200-100, matching the 80mm bore, 200mm nominal stroke, G3/8 port, and 513 kgf max force. An external stop screw lets you trim the extend stroke by up to 100mm on-site, yielding a usable 100-200mm stroke. The stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI for held loads.
This bore delivers 2513N push and 2268N pull at 0.5MPa, rising to 4523N at 0.9MPa. The safe working load is roughly 1508N (60% of the 0.5MPa push), giving a 128kg vertical lift with a 2:1 margin. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure, and the SAI family adds SAIF and BSAI variants. This non-S SKU lacks a magnet and cannot take a switch.

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 SAIJ80X200-100 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 SIJ80X200-100 Is Used
Variable-depth pressing
Trimming the extend stroke by up to 100mm on-site allows operators to set precise pressing depths for 80mm bore assemblies without changing the cylinder.
Adjustable transfer stops
An external stop screw provides field-tuned end positions for diverter arms handling varied package sizes, with 2268N pull force at 0.5MPa.
Modular positioning pins
Dialing the extend stroke from 200mm down to 100mm accommodates different pallet widths, setting the exact end position for locating pins.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-100 with the SAIJ80X200-100
To replace the discontinued SIJ80X200-100, order the drop-in SAIJ80X200-100, reusing your existing FA, LB, or TC ISO 15552 mounts. To size both ways: the neighboring 63mm bore yields 2182N push at 0.7MPa, while the 100mm bore yields 5497N push at 0.7MPa. Choose the 100mm adjust window if you need to trim the 200mm extend stroke down to a 100mm minimum on-site. Because this is a non-S model, it cannot accept a magnetic switch; add an external sensor if needed. For strokes of 300mm or more, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-100
- ✓ 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 SIJ80X200-100 FAQ
Yes, the SIJ80X200-100 is discontinued. The exact drop-in replacement is the SAIJ80X200-100. It shares the same ISO 15552 interface, 80mm bore, 200mm stroke, 100mm adjust window, G3/8 port, and mounting options. The SAIJ uses an upgraded two Y-shaped one-way piston seal for longer life.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa. The external stop screw window is 100mm, allowing you to shorten the 200mm nominal extend stroke down to 100mm on-site. The stop sets end position but is not a load lock.
