This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X75-30S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X75-30S 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 SIJ200X75-30S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30S 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 SAIJ200X75-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30S
The AirTAC SIJ200X75-30S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore, 75mm maximum stroke, and a built-in magnetic piston (-S). An external stop screw allows you to trim the extend stroke by up to 30mm on-site, yielding a usable extend range of 45-75mm. The stop screw strictly sets the end position and is not a load lock; the cylinder will drift on air loss. Delivering 15708N push and 15080N pull at 0.5MPa via a G3/4 port, it features 50mm adjustable air cushions at each end.
Because this model is end-of-life, the exact drop-in replacement is the SAIJ200X75-30S, preserving the ISO 15552 mounting interface, 75mm stroke, 30mm adjust window, and force ratings. The SAIJ upgrade utilizes an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. For sizing, a safe working load is approximately 9425N (60% of the 0.5MPa push force), and a vertical lift with a 2:1 safety margin handles about 801kg. Note that a plain cylinder does not hold loads without live air; for held loads use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variants.

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 SAIJ200X75-30S 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 SIJ200X75-30S Is Used
Heavy Stamping Pin Placement
Allows operators to dial in the exact 45-75mm extend position for a stamping pin on varying material thicknesses without changing the entire cylinder setup.
Pallet Positioning Stops
Provides an adjustable physical end-stop for large pallets, trimming the extend stroke by up to 30mm on-site to accommodate different pallet depths.
Heavy Forming Press Stroke Tuning
Enables fine-tuning of the extend stroke during heavy forming operations, ensuring precise contact without over-traveling the 200mm bore mechanism.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-30S with the SAIJ200X75-30S
To replace the discontinued SIJ200X75-30S, order the drop-in SAIJ200X75-30S, which matches the 200mm bore, 75mm nominal stroke, 30mm adjust window, G3/4 port, and ISO 15552 mounting. When sizing both ways, the neighboring 160mm bore yields 10053N push at 0.5MPa, while the 200mm bore provides 15708N push at 0.5MPa (21991N at 0.7MPa). Select the 30mm adjust window if your application requires field tuning the extend stroke between 45mm and 75mm. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches; the SAIJ replacement uses current AirTAC switches. For this 75mm stroke, side-load is minimal, but for any stroke >=300mm, ensure guide rails to prevent rod binding. The stop screw sets end position only and is not a lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-30S
- ✓ 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 SIJ200X75-30S FAQ
Yes, the AirTAC SIJ200X75-30S is discontinued. The exact drop-in replacement is the SAIJ200X75-30S. It shares the same ISO 15552 interface, 200mm bore, 75mm stroke, 30mm adjust window, G3/4 port, and mounting. The SAIJ features an upgraded piston seal for longer life.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N push at 0.9MPa (theoretical max 3204 kgf at 1.0MPa). The external stop screw window is 30mm, allowing the extend stroke to be shortened on-site from the 75mm maximum down to 45mm. The stop sets end position only; it is not a load lock.
