This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X600-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X600-30 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 SIJ80X600-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X600-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-30
The AirTAC SIJ80X600-30 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 30 mm on-site, giving a usable 570-600 mm stroke (600 mm nominal maximum). The 80 mm bore delivers 2513 N push and 2268 N pull at 0.5 MPa, features a 25 mm rod, M20x1.5 thread, and a fixed G3/8 port. This exact model is end-of-life; the drop-in replacement is the SAIJ80X600-30, matching the interface, force, and mounting.
The SAIJ successor retains the adjustable cushion (36 mm) and adds an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Computed buyer insight: safe working load is roughly 1508 N (60% of the 2513 N push at 0.5 MPa), yielding a 128 kg vertical lift with a 2:1 margin. Note: this non-magnetic SKU cannot take a sensor switch. The external stop sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X600-30 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 SAIJ80X600-30 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 SIJ80X600-30 Is Used
Press Fit Tuning
Dialing in a 570-600 mm insertion depth for press-fit assemblies where the exact 30 mm extend stop must be set on-site to avoid crushing the workpiece.
Variable Length Diverter
Actuating a diverter arm on a conveyor where product lengths vary, allowing the 30 mm external stop to adjust the extend endpoint without reprogramming logic.
Adjustable Pallet Stop
Deplying a physical end-stop for pallets of varying widths, using the 570-600 mm stroke window to fine-tune the stopping position mechanically.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-30 with the SAIJ80X600-30
To replace the discontinued SIJ80X600-30, order the drop-in SAIJ80X600-30 (insert A after the leading S), keeping the 600 mm stroke, 30 mm adjust window, and G3/8 port. Size both ways using 0.5 MPa push force: step down to a 63 mm bore (1559 N) for lighter loads, or up to a 100 mm bore (3927 N) if you need more thrust. Choose the 30 mm adjust window when you need precise 570-600 mm extend tuning. Mounting interfaces (FA, LB, TC) reuse existing ISO 15552 fixtures. Because this is a non-S SKU, it cannot accept legacy CS1-B/DS1-B sensors. For the 600 mm stroke, ensure external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-30
- ✓ 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 SIJ80X600-30 FAQ
Yes, the SIJ80X600-30 is discontinued. The exact drop-in replacement is the SAIJ80X600-30. It shares the same ISO 15552 interface, 80 mm bore, 600 mm stroke, 30 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal.
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 push at 0.9 MPa, and a theoretical max of 513 kgf at 1.0 MPa. The external stop screw window is 30 mm, allowing the extend stroke to be shortened from 600 mm down to 570 mm on-site. The stop sets end position only; it is not a load lock.
