This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-40 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 SIJ80X175-40
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 175mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X175-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-40
The AirTAC SIJ80X175-40 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 80mm bore and 175mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, giving a usable 135-175mm window. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port, with a 25mm rod and M20x1.5 thread. The exact drop-in replacement is the SAIJ80X175-40, matching the interface, force, and mounts.
The SAIJ upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For sizing, a safe working load is roughly 1508N (60% of the 0.5MPa push), yielding a 128kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads. This non-magnetic SKU cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X175-40 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 SAIJ80X175-40 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 SIJ80X175-40 Is Used
Press Fit Tuning
Adjusts the extend stroke on-site to set precise pressing depths for bearing insertion without swapping the entire actuator.
Variable Length Diverter
Trims the extend position to deflect varying package sizes on a line, ensuring positive contact without repositioning the cylinder mount.
Adjustable End Stop
Sets a custom mechanical end position for pallet stops, allowing quick 40mm changes to the extend limit to accommodate different pallet heights.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-40 with the SAIJ80X175-40
To replace the discontinued SIJ80X175-40, order the drop-in SAIJ80X175-40. 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 40mm adjust window if your field stroke tuning requires trimming the 175mm extend down to 135mm; the stop sets end position and is not a lock. Mounting interchange via the ISO 15552 interface supports Basic, FA, LB, and TC brackets. This SKU lacks the -S magnet and cannot support a legacy CS1-B or DS1-B sensor. For strokes of 300mm or longer, verify side-load guidance to prevent rod deflection.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X175-40
- ✓ 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 SIJ80X175-40 FAQ
Yes, the SIJ80X175-40 is discontinued. The exact drop-in replacement is the SAIJ80X175-40. It shares the identical ISO 15552 interface, 175mm stroke, 40mm adjust window, 4523N force at 0.9MPa, G3/8 port, and mounting options, but adds an upgraded piston seal.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a 513kgf max at 1.0MPa. The external stop screw provides a 40mm adjust window, shortening the 175mm extend stroke down to 135mm on-site. The stop sets end position and is not a load lock.
