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

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-20FA
The AirTAC SIJ200X75-20FA is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, giving a usable 55-75 mm extension out of the 75 mm nominal maximum. The 200 mm bore yields 15708 N push and 15080 N pull at 0.5 MPa, scaling to 28274 N push at 0.9 MPa. It features a 40 mm rod, M36x2 thread, 50 mm adjustable cushions, G3/4 port, and an FA foot mount. This SKU lacks a magnet (-S) and cannot accept a magnetic switch.
The exact drop-in replacement is the SAIJ200X75-20FA, matching the ISO 15552 interface, bore, force, and FA mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 9425 N (60% of the 0.5 MPa push), equating to an 801 kg vertical lift with a 2:1 margin. The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X75-20FA 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 SAIJ200X75-20FA 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 SIJ200X75-20FA Is Used
Heavy Press Tonnage
Delivers 21991 N push at 0.7 MPa for high-force forming, using the 20 mm stop screw to fine-tune the 75 mm extend stroke for precise material contact.
Large Mold Positioning
Handles 3204 kgf theoretical max force at 1.0 MPa, allowing operators to field-trim the extension down to 55 mm to accommodate varying mold thicknesses.
Pallet Stop Mechanism
Uses the FA foot mount to secure the 200 mm bore cylinder, adjusting the stop screw on-site to set exact 55-75 mm end positions for diverter alignment.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-20FA with the SAIJ200X75-20FA
To replace the discontinued SIJ200X75-20FA, order the SAIJ200X75-20FA. It is a true drop-in: identical 200 mm bore, 75 mm stroke, 20 mm adjust window, G3/4 port, and FA foot mount interface. When sizing both ways, the neighbouring 160 mm bore gives 10053 N push at 0.5 MPa, while this 200 mm bore provides 15708 N. Choose the 20 mm adjust window when you need on-site tuning of the extend stroke from 55 to 75 mm. The FA mount is included; ISO 15552 mounting interchangeability lets you reuse existing FA, LB, or TC brackets. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. Note: for any stroke, ensure side-load limits are respected, and never rely on the stop screw or 50 mm air cushion to hold a load on air loss—install a pilot-operated check valve or external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-20FA
- ✓ 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 SIJ200X75-20FA FAQ
Yes, the AirTAC SIJ200X75-20FA is discontinued. The exact drop-in replacement is the SAIJ200X75-20FA, offering the same ISO 15552 interface, 200 mm bore, 75 mm stroke, 20 mm adjust window, G3/4 port, and FA mount. The SAIJ family also features an upgraded two Y-shaped one-way piston seal.
The 200 mm bore single-rod cylinder delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa (theoretical max 3204 kgf at 1.0 MPa). The external stop screw provides a 20 mm adjust window, allowing you to shorten the 75 mm extend stroke down to 55 mm. The stop sets end position only; it is not a load lock.
