This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ80X200-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ80X200-40 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 SIJ80X200-40
The AirTAC Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40 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 SAIJ80X200-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40
The AirTAC SIJ80X200-40 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with an 80mm bore and 200mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 160-200mm extension window. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port, with a 36mm adjustable air cushion at each end. The exact drop-in replacement is the SAIJ80X200-40, preserving the original interface, bore, force, and mounting.
The SAIJ successor introduces an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Because this specific SKU lacks a -S magnet, it cannot accept a magnetic switch for position sensing. For sizing, the 2513N push at 0.5MPa translates to a safe working load of roughly 1508N, or a vertical lift capacity of about 128kg with a 2:1 safety margin. Note the stop screw sets the end position but is not a load lock; the piston drifts on air loss, so use an external rod lock for held loads.

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 SAIJ80X200-40 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 SIJ80X200-40 Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to control drill depth precisely without swapping the entire cylinder setup.
Variable Push-off Diverter
Tunes the pusher stroke length on a packaging line to handle different carton widths using the external stop.
Adjustable Stacking Stop
Sets the exact end position for stacking varying product heights, allowing quick field changes to the extend limit.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-40 with the SAIJ80X200-40
To replace the discontinued SIJ80X200-40, order the drop-in SAIJ80X200-40, which matches the 80mm bore, 200mm nominal stroke, 40mm adjust window, and G3/8 port. When sizing both ways, the neighboring 63mm bore yields 1559N push at 0.5MPa, while the 100mm bore yields 3927N push at 0.5MPa. Choose the 40mm adjust window if your extend stroke needs on-site tuning between 160mm and 200mm. Reuse existing FA, LB, or TC ISO 15552 mounting hardware. As this SKU has no -S suffix, it cannot support magnetic switches. For strokes of 300mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-40
- ✓ 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 SIJ80X200-40 FAQ
Yes, the SIJ80X200-40 is discontinued. The exact drop-in replacement is the SAIJ80X200-40, which shares the identical ISO 15552 interface, 80mm bore, 200mm stroke, 40mm adjust window, and G3/8 port.
The 80mm bore delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, and 4523N push at 0.9MPa. The external stop screw provides a 40mm adjust window, allowing the extend stroke to be shortened from the 200mm maximum down to 160mm on-site.
