This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-100 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 SIJ80X175-100
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100 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 SAIJ80X175-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100
The AirTAC SIJ80X175-100 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, yielding a usable 75-175 mm window from the 175 mm nominal maximum. The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa via a G3/8 port, with adjustable 36 mm cushions at each end.
The exact drop-in replacement is the SAIJ80X175-100, matching the interface, force, and mounting. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Computed buyer insight: safe working load is ~1508 N (60% of the 2513 N push @0.5 MPa), or a ~128 kg vertical lift with a 2:1 margin. This SKU lacks a -S magnet, so it cannot take a magnetic switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X175-100 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 SAIJ80X175-100 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 SIJ80X175-100 Is Used
Variable-depth Forming Press
Dial in the exact bottoming height on-site by trimming the extend stroke up to 100 mm, preventing over-travel on varying material thicknesses.
Adjustable Transfer Pusher
Accommodate changing package widths on a line by fine-tuning the extend stroke within the 75-175 mm window without swapping the cylinder.
Modular End-Stop Positioning
Set precise mechanical end stops for pallets or fixtures on demand, relying on the external screw to define the final resting position.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-100 with the SAIJ80X175-100
To replace the discontinued SIJ80X175-100, specify SAIJ80X175-100 for an exact drop-in. Size both ways using 0.5 MPa force: the 63 mm bore yields 1559 N push, while the 100 mm bore yields 3927 N. The 100 mm adjust window is ideal if your end-position target varies by up to 100 mm. Reuse FA, LB, or TC ISO 15552 mounts. Because this SKU has no -S magnet, sensing is impossible; add an external switch if needed. For strokes of 300 mm or longer, verify side-load guidance. The stop screw sets end position but is not a lock; for load holding on air loss, use an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X175-100
- ✓ 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 SIJ80X175-100 FAQ
Yes, the SIJ80X175-100 is discontinued. The exact drop-in replacement is the SAIJ80X175-100, offering the same ISO 15552 interface, 175 mm stroke, 100 mm adjust window, and G3/8 port. The SAIJ family also uses an upgraded two-piece Y-shaped piston seal for longer life.
The 80 mm bore provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N at 0.9 MPa, and a 513 kgf max at 1.0 MPa. The external stop screw trims the extend stroke by up to 100 mm on-site, giving a usable 75-175 mm window. The stop sets end position and is not a load lock.
