This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-30 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 SIJ200X800-30
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X800-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30
The AirTAC SIJ200X800-30 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and 800 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 770-800 mm extend window. The 200 mm 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 fixed G3/4 port with an M36x2 rod thread. This SKU has no -S magnet and cannot accept a magnetic switch.
As the SIJ family is end-of-life, the exact drop-in replacement is the SAIJ200X800-30, preserving the ISO 15552 mounting interface, bore, force, adjust window, and port. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Computed buyer insight: using 60% of the 0.5 MPa push force yields a safe working load of 9425 N, and a 2:1 safety margin allows a vertical lift of roughly 801 kg. Note the stop screw sets end position only; it is not a load lock, so use an external rod lock or pilot-operated check valve for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X800-30 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 SAIJ200X800-30 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 SIJ200X800-30 Is Used
Heavy Press Tonnage Calibration
Trimming the 800 mm extend stroke by up to 30 mm on-site allows operators to set exact bottom-dead-center for a 200 mm bore press without machining spacers.
Oversized Pallet Positioning
The 15708 N push force at 0.5 MPa moves heavy pallets, while the external stop screw provides a 770-800 mm usable window to adapt to varying load lengths.
Large Mold Closing Height Adjustment
Fine-tune the final closing position of large injection molds on-site by dialing the stop screw, avoiding complete machine teardown when mold heights vary slightly.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-30 with the SAIJ200X800-30
To replace the discontinued SIJ200X800-30, order the drop-in SAIJ200X800-30, which retains the exact 30 mm adjust window, 800 mm nominal stroke, G3/4 port, and ISO 15552 mounting. Size both ways by checking the neighbours: the 160 mm bore gives 10053 N push @0.5 MPa, while the 200 mm bore gives 15708 N. Choose the 30 mm adjust window if you need precise 770-800 mm extend tuning. Reuse FA, LB, or TC mounts directly. Because this SKU lacks the -S magnet, it cannot support sensing; add external sensors if needed. For the 800 mm stroke, support the rod against side-load bending and use external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-30
- ✓ 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 SIJ200X800-30 FAQ
Yes, the SIJ200X800-30 is discontinued. The exact drop-in replacement is the SAIJ200X800-30. It shares the same ISO 15552 interface, 200 mm bore, 800 mm stroke, 30 mm adjust window, G3/4 port, and mounting options. The SAIJ family also upgrades the piston seal to a two Y-shaped one-way element design for lower start-up pressure and longer life.
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 theoretical max of 3204 kgf at 1.0 MPa. The external stop screw provides a 30 mm adjust window, meaning the usable extend stroke is 770-800 mm. The stop sets end position only and is not a load lock; use an external rod lock for held loads.
