This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X75-20S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X75-20S 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 SIJ200X75-20S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-20S 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 SAIJ200X75-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-20S
The AirTAC SIJ200X75-20S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and 75 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 55-75 mm extension window. This bore delivers 15708 N push and 15080 N pull at 0.5 MPa, features a 50 mm adjustable air cushion at each end, and uses a G3/4 port. The exact drop-in replacement is the SAIJ200X75-20S, sharing the same interface, force, and mounting.
The SAIJ successor incorporates an upgraded piston seal utilizing two Y-shaped one-way elements for low start-up pressure and extended life. For sizing, the safe working load is roughly 9425 N (60% of the 0.5 MPa push), translating to a vertical lift capacity of about 801 kg with a 2:1 margin. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X75-20S 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 SAIJ200X75-20S 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 SIJ200X75-20S Is Used
Heavy Press Tonnage Calibration
Apply up to 28274 N of push at 0.9 MPa for high-force pressing, trimming the extend stroke by up to 20 mm on-site to dial in exact material contact distance.
Large Mold Positioning
Shift heavy 801 kg vertical loads using the 200 mm bore, relying on the 55-75 mm usable extend window to fine-tune mold seating without machining spacers.
Industrial Stamper Depth Control
Execute 75 mm maximum extend strokes for stamping, adjusting the external stop screw to shorten the stroke precisely when varying material thicknesses require different depths.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-20S with the SAIJ200X75-20S
To replace the discontinued SIJ200X75-20S, order the exact drop-in SAIJ200X75-20S, retaining the 200 mm bore, 75 mm stroke, 20 mm adjust window, G3/4 port, and -S magnet. When sizing both ways, the neighboring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N at 0.5 MPa and 21991 N at 0.7 MPa. The 20 mm adjust window is ideal if your extend end-position needs field tuning between 55 and 75 mm. Mounting options include Basic, FA, LB, and TC brackets. Because the nominal stroke is 75 mm, the stroke is under 300 mm and side-load shaft deflection is minimal. The -S magnet enables legacy CS1-B/DS1-B sensor accuracy; no-S means no sensor.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-20S
- ✓ 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 SIJ200X75-20S FAQ
Yes, the SIJ200X75-20S is discontinued. The exact drop-in replacement is the SAIJ200X75-20S. It shares the same ISO 15552 interface, 200 mm bore, 75 mm nominal stroke, 20 mm adjust window, G3/4 port, and mounting options, but features an upgraded piston seal.
The 200 mm bore provides 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a 3204 kgf max at 1.0 MPa. The external stop screw provides a 20 mm adjust window, shortening the 75 mm nominal extend stroke to a usable 55-75 mm. The stop sets end position only and is not a load lock.
