This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X800-50S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X800-50S 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 SIJ200X800-50S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-50S 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 SAIJ200X800-50S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-50S
The AirTAC SIJ200X800-50S is a double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 800mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 50mm on-site, giving a usable 750-800mm window. This bore delivers 15708N push and 15080N pull at 0.5MPa via a G3/4 port. The SIJ series is discontinued; the exact drop-in replacement is the SAIJ200X800-50S, sharing the same interface, force, and mounting.
The SAIJ upgrade features an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. For sizing, a safe working load is roughly 9425N (60% of the 0.5MPa push), yielding an 801kg vertical lift capacity with a 2:1 margin. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X800-50S 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 SAIJ200X800-50S 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 SIJ200X800-50S Is Used
Heavy Press Tonnage
Provides 15708N push at 0.5MPa for large forming presses, using the 50mm stop screw to fine-tune the bottom dead center on-site without shims.
Pallet Positioning Stops
Handles 801kg vertical loads with a 2:1 safety margin, allowing operators to dial in the exact 750-800mm extend position for varying pallet heights.
Large Mold Handling
Shifts heavy tooling with a 40mm rod and M36x2 thread, using the adjustable end-stop to compensate for mold height variances during changeovers.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X800-50S with the SAIJ200X800-50S
To replace the discontinued SIJ200X800-50S, order the drop-in SAIJ200X800-50S, retaining the ISO 15552 mounting interface and G3/4 port. For sizing both ways, the neighbouring 160mm bore yields 10053N push at 0.5MPa, while this 200mm bore yields 15708N. Choose the 50mm adjust window if you need on-site end-position tuning between 750-800mm. Reuse FA, LB, or TC mounts. The -S magnet supports legacy CS1-B/DS1-B switches. Because the 800mm stroke exceeds 300mm, account for rod-bending and use external guides to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X800-50S
- ✓ 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 SIJ200X800-50S FAQ
Yes, the SIJ200X800-50S is discontinued. The exact drop-in replacement is the SAIJ200X800-50S. It shares the same ISO 15552 interface, 200mm bore, 800mm stroke, 50mm adjust window, G3/4 port, and mounting options, while adding an upgraded piston seal.
The 200mm bore provides 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N at 0.9MPa. The external stop screw offers a 50mm adjust window, shortening the 800mm extend stroke down to 750mm. The stop sets end position only; it is not a load lock.
