This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X75-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X75-40 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X75-40
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X75-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-40
The AirTAC SIJ200X75-40 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 75mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 35-75mm window. It delivers 15708N push and 15080N pull at 0.5MPa via its G3/4 port. The exact drop-in replacement is the SAIJ200X75-40, matching the interface, force, and mounts.
Upgrading to the SAIJ brings an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425N (about 60% of the 0.5MPa push), allowing an 801kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. This non-magnetic SKU cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X75-40 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAIJ200X75-40 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 SIJ200 Double Rod Adjustable Cylinder SIJ200X75-40 Is Used
Heavy Press Tonnage
Applies up to 21991N of push force at 0.7MPa for high-tonnage forming operations requiring exact end-position tuning.
Gauge Stop Calibration
Trims the 75mm extend stroke by up to 40mm on-site to dial in material stop positions without machining new spacers.
Large Mold Handling
Shifts heavy tooling using the 40mm rod and M36x2 thread, relying on the 50mm adjustable cushion to decelerate loads.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-40 with the SAIJ200X75-40
Replace the discontinued SIJ200X75-40 directly with the SAIJ200X75-40, reusing your existing FA, LB, or TC ISO 15552 mounting interfaces. To scale force, the 160mm neighbor yields 10053N push, while the 200mm bore provides 15708N push at 0.5MPa. Choose the 40mm adjust window if you need on-site end-position tuning between 35 and 75mm. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; add external detection if needed. For strokes over 300mm, verify side-load guide tolerance.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-40 FAQ
Yes, the SIJ200X75-40 is discontinued. The exact drop-in replacement is the SAIJ200X75-40, which matches the 200mm bore, 75mm stroke, 40mm adjust window, G3/4 port, and ISO 15552 mounting interface. The SAIJ family also adds an upgraded piston seal for longer life.
It delivers 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa, with a theoretical max of 3204kgf at 1.0MPa. The external stop screw provides a 40mm adjust window, allowing you to shorten the 75mm extend stroke down to 35mm. The stop sets end position and is not a load lock.
