This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X175-10S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X175-10S 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 SIJ80X175-10S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-10S 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 SAIJ80X175-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-10S
The AirTAC SIJ80X175-10S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 175mm nominal stroke and a built-in magnetic piston (-S). An external stop screw lets you trim the extend stroke by up to 10mm on-site, yielding a usable 165-175mm extension window. This 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, peaking at 4523N push at 0.9MPa. It features a Ø25mm rod, M20x1.5 rod thread, 36mm adjustable cushions, and a fixed G3/8 port.
The exact drop-in replacement is the SAIJ80X175-10S, retaining the identical ISO 15552 mounting interface, bore, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, the safe working load is roughly 1508N (60% of the 0.5MPa push), translating to a 128kg vertical lift with a 2:1 margin. Note the stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X175-10S 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 SAIJ80X175-10S 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 SIJ80X175-10S Is Used
Press Fit Calibration
Trimming the extend stroke by up to 10mm on-site allows operators to dial in the exact seating depth for bearings without swapping mechanical spacers.
Divertor Gate Adjustment
The 165-175mm adjustable extension window lets maintenance teams fine-tune the actuator reach to accommodate varying package widths on the line.
Sealing Head Positioning
Using the external stop screw to set the precise end position ensures consistent sealing pressure across material thickness variations.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X175-10S with the SAIJ80X175-10S
To replace the discontinued SIJ80X175-10S, order the drop-in SAIJ80X175-10S, reusing your existing FA, LB, or TC ISO 15552 mounts and G3/8 piping. When sizing both ways, the adjacent 63mm bore yields 2182N push at 0.7MPa, while the 100mm bore yields 5497N push at 0.7MPa. The 10mm adjust window is ideal for fine-tuning extend positions without machining spacers; ensure the 165-175mm usable stroke fits your kinematics. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For stroke lengths of 300mm or more, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X175-10S
- ✓ 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 SIJ80X175-10S FAQ
Yes, the SIJ80X175-10S is discontinued. The exact drop-in replacement is the SAIJ80X175-10S, which shares the identical ISO 15552 interface, 80mm bore, 175mm stroke, 10mm 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.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa, with a theoretical max of 513kgf at 1.0MPa. The external stop screw provides a 10mm adjustment window, allowing the extend stroke to be shortened from the 175mm maximum down to 165mm. The stop sets end position and is not a load lock.
