This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-30 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 SIJ80X200-30
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ80X200-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30
The AirTAC SIJ80X200-30 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The exact drop-in replacement is the SAIJ80X200-30, matching the 80mm bore, 200mm nominal stroke, G3/8 port, and 25mm rod. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 170-200mm extend distance. This bore delivers 2513N push and 2268N pull at 0.5MPa, rising to 4523N at 0.9MPa.
The SAIJ successor retains the ISO 15552 mounting interface for direct reuse of FA, LB, and TC brackets, and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure. Computed buyer insight: safe working load is roughly 1508N (60% of the 0.5MPa push), translating to a 128kg vertical lift with a 2:1 margin. Note this SKU lacks a -S magnet (no sensor), and the stop screw sets end position but is not a load lock; use SAIL or an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ80X200-30 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 SAIJ80X200-30 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 SIJ80X200-30 Is Used
Press Fit Tuning
Trimming the extend stroke by up to 30mm on-site allows exact positioning for pressing bearings without machining hard stops.
Divertor Adjustment
Field-tuning the 170-200mm extend distance accommodates varying package sizes on a sorting line without swapping cylinders.
Pallet Stop Calibration
The external stop screw lets operators dial in the exact end position for pallets of varying widths on a 80mm bore actuator.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-30 with the SAIJ80X200-30
To replace the discontinued SIJ80X200-30, order the drop-in SAIJ80X200-30. For sizing both ways, the neighbouring 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N. This 80mm model provides 2513N push at 0.5MPa. The 30mm adjust window is ideal if your end position needs minor field tuning; for larger trims, pick a bigger adjust figure. Mounting interfaces (Basic, FA, LB, TC) are ISO 15552 standard. Because this SKU has no -S magnet, it cannot accept a magnetic switch; add -S if sensing is required. For strokes >=300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-30
- ✓ 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 SIJ80X200-30 FAQ
Yes, the SIJ80X200-30 is discontinued. The exact drop-in replacement is the SAIJ80X200-30. It shares the same ISO 15552 interface, 80mm bore, 200mm stroke, 30mm adjust window, G3/8 port, and 25mm rod. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure.
The 80mm bore provides 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa (max 513 kgf at 1.0MPa). The external stop screw allows trimming the extend stroke by up to 30mm on-site (usable extend 170-200mm). The stop sets end position only; it is not a load lock. Speed is 30-800 mm/s.
