This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X75-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X75-75S 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 SIJ80X75-75S
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 75mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X75-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-75S
The AirTAC SIJ80X75-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 75 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, setting the exact end position without custom machining. The exact drop-in replacement is the SAIJ80X75-75S, retaining the 80 mm bore, G3/8 port, M20x1.5 rod thread, and 36 mm adjustable air cushions. It delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa.
The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, the safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift capacity with a 2:1 margin. The stop screw dictates end position but is not a lock; loads drift on air loss, so use an external rod lock or the SAIL/BSAI variants for holding. This -S model includes a piston magnet for legacy CS1-B/DS1-B sensors.

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 SAIJ80X75-75S 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 SIJ80X75-75S Is Used
Variable Depth Drilling
Allows operators to dial in the exact extend stop for drilling different material thicknesses on the same fixture without swapping cylinders.
Adjustable Diverter Gate
Tunes the extend stroke on-site to accommodate varying package widths on a packaging line, ensuring precise routing without reprogramming.
Variable Height Pallet Stop
Provides a field-adjustable end position for pallets of varying heights, allowing quick mechanical changes to the stop distance.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-75S with the SAIJ80X75-75S
To replace the discontinued SIJ80X75-75S, order the SAIJ80X75-75S, ensuring you keep the -S suffix for the piston magnet. The 75 mm adjust window means you can tune the extend stroke down to 0 mm on-site, which is ideal when the exact extend target is unknown at build time. If sizing both ways, the neighbouring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa. Mounting interfaces include Basic, FA, LB, and TC, all reusable via the ISO 15552 dimensions. Because the stroke is under 300 mm, side-load rod deflection is minimal. Note that speed is 30-800 mm/s, and the stop screw sets position only—it provides no load-holding capability.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X75-75S
- ✓ 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 SIJ80X75-75S FAQ
Yes, the SIJ80X75-75S is discontinued. The exact drop-in replacement is the SAIJ80X75-75S, which shares the identical ISO 15552 interface, 80 mm bore, 75 mm stroke, 75 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two-piece Y-shaped piston seal.
It is a double-acting single-rod cylinder with a 25 mm rod, M20x1.5 thread, and G3/8 port. Forces are: push 2513 N / pull 2268 N at 0.5 MPa; push 3518 N at 0.7 MPa; push 4523 N at 0.9 MPa; max 513 kgf at 1.0 MPa. The nominal 75 mm extend stroke can be shortened by up to 75 mm via the external stop screw. Speed is 30-800 mm/s, and it uses 36 mm adjustable cushions.
