This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-75 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-75 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 SIJ200X80-75
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X80-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-75
The AirTAC SIJ200X80-75 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. The external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 5-80 mm extension from the 80 mm nominal maximum. This 200 mm bore delivers a push force of 15708 N and pull of 15080 N at 0.5 MPa, features a 50 mm adjustable air cushion, and uses a fixed G3/4 port.
Because this SIJ series is end-of-life, the exact drop-in replacement is the SAIJ200X80-75, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer 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. Note: the stop screw sets end position but is not a load lock; use SAIL or BSAI for holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-75 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 SAIJ200X80-75 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 SIJ200X80-75 Is Used
Heavy Press Tonnage
Provides 28274 N push at 0.9 MPa for high-force stamping, allowing on-site extend tuning to accommodate varying material thicknesses without re-plumbing the G3/4 air lines.
Industrial Forming Stops
Uses the external stop screw to set precise bottoming positions up to 75 mm short of the 80 mm nominal stroke, ensuring repeatable metal forming without relying on machine hard stops.
Large Payload Positioning
Shifts heavy 801 kg vertical loads with a 2:1 safety margin at 0.5 MPa, offering field-adjustable extend endpoints to adapt to different pallet sizes on the fly.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-75 with the SAIJ200X80-75
To replace the discontinued SIJ200X80-75, order the drop-in SAIJ200X80-75, matching the 200 mm bore, 80 mm stroke, 75 mm adjust window, and G3/4 port. When sizing both ways, the neighbouring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore hits 21991 N at 0.7 MPa. Choose the 75 mm adjust window if your application needs aggressive on-site end-position tuning down to a 5 mm extend. Mounting options include FA, LB, and TC. This SKU lacks the -S magnet and cannot take a magnetic switch. For strokes >=300 mm, verify side-load guidance to prevent rod binding. The stop screw is not a lock; drifting occurs on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-75
- ✓ 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 SIJ200X80-75 FAQ
Yes, the AirTAC SIJ200X80-75 is discontinued. The exact drop-in replacement is the SAIJ200X80-75. It shares the identical ISO 15552 interface, 200 mm bore, 80 mm stroke, 75 mm adjust window, and G3/4 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
The 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N at 0.9 MPa, and a 3204 kgf max at 1.0 MPa. The external stop screw provides a 75 mm adjust window, shortening the 80 mm nominal extend stroke down to 5 mm. The stop sets end position and is not a load lock; use SAIL or BSAI for load holding.
