This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-20 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-20 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 SIJ200X800-20
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-20 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 SAIJ200X800-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-20
The AirTAC SIJ200X800-20 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The drop-in replacement is the SAIJ200X800-20, matching the 200mm bore, 800mm nominal stroke, G3/4 port, and 20mm adjust window. You trim the extend stroke by up to 20mm on-site via an external stop screw, yielding a usable 780-800mm extend range. This bore delivers 15708N push and 15080N pull at 0.5MPa, rising to 28274N push at 0.9MPa.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push), equating to an 801kg vertical lift with a 2:1 margin. This SKU lacks a -S magnet, so it cannot take a switch. The stop screw sets end position but is not a lock; use SAIL or BSAI for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X800-20 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 SAIJ200X800-20 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 SIJ200X800-20 Is Used
Heavy Press Tonnage
Needs field stroke tuning to dial in the exact 780-800mm contact point on large press tools, absorbing 28274N push at 0.9MPa without re machining hard stops.
Large Mold Actuation
Requires trimming the extend stroke by up to 20mm on-site to accommodate varying mold thicknesses, relying on the 50mm adjustable cushion to decelerate the massive 200mm bore payload.
Bulk Material Diversion
Demands precise end-position adjustment for heavy diverter arms, using the 15080N pull force at 0.5MPa while fitting existing G3/4 pneumatic lines.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-20 with the SAIJ200X800-20
To replace the discontinued SIJ200X800-20, order the SAIJ200X800-20 drop-in, reusing your ISO 15552 FA, LB, or TC mounts. The 20mm adjust window lets you tune the extend end-position by up to 20mm on-site. If you need less force, the neighbouring 160mm bore yields 14074N push at 0.7MPa; if scaling up is impossible, the 200mm bore provides 21991N push at 0.7MPa. Because the 800mm stroke is long, use external guides to prevent rod bending and side-load damage. This non-magnetic SKU cannot accept legacy CS1-B or DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-20
- ✓ 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 SIJ200X800-20 FAQ
Yes, the SIJ200X800-20 is discontinued. The exact drop-in replacement is the SAIJ200X800-20. It shares the identical ISO 15552 interface, 200mm bore, 800mm stroke, 20mm adjust window, G3/4 port, and mounting options, but adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, 28274N push at 0.9MPa, and a theoretical max of 3204 kgf at 1.0MPa. The external stop screw allows you to trim the extend stroke by up to 20mm on-site (usable range 780-800mm). The stop sets end position and is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.
