This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-75 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 SIJ80X200-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75 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 SAIJ80X200-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75
The AirTAC SIJ80X200-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. A 200 mm nominal extend stroke is shortened on-site by an external stop screw, trimming up to 75 mm to yield a 125-200 mm usable window. The 80 mm bore uses a G3/8 port, a Ø25 mm rod, and 36 mm adjustable cushions. The drop-in replacement is the SAIJ80X200-75, matching the ISO 15552 mounting interface, force, and stroke.
Force outputs are 2513 N push and 2268 N pull at 0.5 MPa, reaching 4523 N at 0.9 MPa. The SAIJ upgrade introduces 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), allowing a 128 kg vertical lift with a 2:1 margin. The stop screw sets end position only; it is not a load lock.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X200-75 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 SAIJ80X200-75 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 SIJ80X200-75 Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to set precise drilling depths for different material thicknesses without swapping cylinders.
Variable Position Diverter
Tunes the extend stop to deflect varying package sizes on a conveyor line, allowing rapid format changeovers.
Adjustable Height Stops
Sets different end-stop positions for palletizing tasks, accommodating multiple pallet heights with a single actuator.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75 with the SAIJ80X200-75
To replace the discontinued SIJ80X200-75, order the exact drop-in SAIJ80X200-75, keeping the 200 mm nominal stroke and 75 mm adjust window. Size both ways: the 63 mm neighbor yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N at 0.7 MPa. Choose the 75 mm window when you need field tuning from 125 to 200 mm; a smaller window gives a stiffer stop. Mounting reuses ISO 15552 FA, LB, or TC interfaces. This SKU lacks the -S magnet, so it cannot take a magnetic switch. For stroke lengths >=300 mm, verify side-load limits to prevent rod binding. The stop screw sets end position only; for load holding without live air, use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-75
- ✓ 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 SIJ80X200-75 FAQ
Yes, the SIJ80X200-75 is discontinued. The exact drop-in replacement is the SAIJ80X200-75. It matches the ISO 15552 interface, 80 mm bore, 200 mm stroke, 75 mm adjust window, G3/8 port, and mounting dimensions, while adding an upgraded piston seal.
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. The external stop screw trims the extend stroke by up to 75 mm on-site, giving a 125-200 mm usable window. The stop sets end position only; it is not a load lock.
