This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X75-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X75-75 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 SIJ80X75-75
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-75 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 SAIJ80X75-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-75
The AirTAC SIJ80X75-75 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 75 mm on-site (usable extend range 0-75 mm from the 75 mm maximum). The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, scaling to 4523 N at 0.9 MPa, with a G3/8 port and 36 mm adjustable cushions. The exact drop-in replacement is the SAIJ80X75-75, retaining the same interface, force, and mounting.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 1508 N (60% of the 0.5 MPa push), yielding a 128 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet (-S) so it cannot take a switch, and the stop screw sets end position—it is not a load lock; use SAIL/BSAI or an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X75-75 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 SAIJ80X75-75 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 SIJ80X75-75 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 75 mm on-site allows precise press-fit depth adjustments without machining custom spacers.
Divert Stop Positioning
Adjusting the end position on the fly accommodates varying package sizes on a divert line, setting the exact stop location.
Pallet Cushioning
Shortening the extend stroke modifies the stopping point to gently decelerate varying pallet loads using the 36 mm cushion.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-75 with the SAIJ80X75-75
To replace the discontinued SIJ80X75-75, order the drop-in SAIJ80X75-75, keeping the 75 mm nominal stroke and 75 mm adjust window. Size both ways by checking neighbors: the 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N. Reuse your FA, LB, or TC ISO 15552 mounts. Because this SKU has no -S magnet, it cannot accept a sensor; add an external switch bracket if sensing is needed. For strokes >=300 mm, verify side-load tolerance to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X75-75
- ✓ 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 SIJ80X75-75 FAQ
Yes, the SIJ80X75-75 is discontinued. The exact drop-in replacement is the SAIJ80X75-75, offering the same ISO 15552 interface, 80 mm bore, 75 mm stroke, 75 mm adjust window, G3/8 port, and mounting compatibility.
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 window is 75 mm, allowing you to trim the extend stroke on-site. The stop sets end position and is not a load lock.
