This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X500-100 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X500-100 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 SIJ80X500-100
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X500-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100
The AirTAC SIJ80X500-100 is a discontinued double-acting, single-rod ISO 15552 adjustable-stroke cylinder with a 500 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable extend range of 400-500 mm. The stop sets the end position; it is not a load lock, and the cylinder will drift on air loss. It delivers 2513 N push and 2268 N pull at 0.5 MPa, peaking at 4523 N push at 0.9 MPa.
The exact drop-in replacement is the SAIJ80X500-100, preserving the 80 mm bore, 25 mm rod, M20x1.5 thread, and 36 mm adjustable cushions. 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. This non-magnetic SKU cannot take a switch; for load holding use SAIL or BSAI.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X500-100 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 SAIJ80X500-100 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 SIJ80X500-100 Is Used
Variable-Length Pressing
Trimming the extend stroke by up to 100 mm on-site allows a press to accommodate varying material thicknesses without re-mounting the actuator.
Adjustable Diverter Arm
A 400-500 mm extend range provides flexibility to reposition a sorting gate for different package sizes on a moving belt.
Variable-Depth Palletizing
Field-tuning the end position lets a pusher adapt to varying pallet depths, ensuring consistent placement without changing cylinder hardware.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100 with the SAIJ80X500-100
To replace the discontinued SIJ80X500-100, order the drop-in SAIJ80X500-100, which matches the ISO 15552 mounting interface, 80 mm bore, 500 mm stroke, 100 mm adjust window, and G3/8 port. When sizing both ways, the neighboring 63 mm bore yields 2182 N push at 0.7 MPa, while the 100 mm bore yields 5497 N push at 0.7 MPa. Choose the 100 mm adjust window if your end-position tuning requires trimming the full 100 mm off the 500 mm nominal stroke. Reuse FA, LB, or TC mounts directly. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. For the 500 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X500-100
- ✓ 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 SIJ80X500-100 FAQ
Yes, the SIJ80X500-100 is discontinued. The exact drop-in replacement is the SAIJ80X500-100, which shares the same ISO 15552 interface, 80 mm bore, 500 mm stroke, 100 mm adjust window, G3/8 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal.
It provides 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and 4523 N push at 0.9 MPa, with a theoretical max of 513 kgf at 1.0 MPa. The external stop screw window is 100 mm, allowing you to shorten the 500 mm nominal extend stroke down to 400 mm. The stop sets end position only; it is not a load lock.
