This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-30 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-30 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 SIJ200X80-30
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-30 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 SAIJ200X80-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-30
The AirTAC SIJ200X80-30 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 30 mm on-site, giving a usable extend range of 50-80 mm. This 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. As a drop-in replacement, the SAIJ200X80-30 matches the exact interface, bore, force, and mounting.
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), translating to an 801 kg vertical lift with a 2:1 margin. The stop screw sets end position but is not a lock; cylinders drift on air loss, so use an external rod lock or SAIL/BSAI variant for held loads. This non-magnetic SKU lacks a -S sensor groove and cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-30 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 SAIJ200X80-30 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 SIJ200X80-30 Is Used
Heavy Press Tonnage Calibration
Needs field stroke tuning to precisely set the 200mm bore contact point on heavy workpieces, trimming the extend stroke by up to 30mm to avoid over-travel damage.
Large Mold Positioning
Requires exact end-position adjustment during setup, using the external stop screw to dial in the 50-80mm extend window without re-mounting the ISO 15552 cylinder.
Oversized Pallet Diverter
Demands on-site stroke trimming to accommodate varying pallet depths, relying on the 15708N push force at 0.5MPa to redirect heavy loads safely.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-30 with the SAIJ200X80-30
To replace the discontinued SIJ200X80-30, order the drop-in SAIJ200X80-30, which preserves the 80 mm nominal stroke, 30 mm adjust window, G3/4 port, and 50 mm cushions. Size both ways by checking neighbor bores: the 160 mm bore yields 10053 N push @0.5 MPa, while the 200 mm bore provides 15708 N. Select the 30 mm adjust window if your application requires field tuning the extend stroke down to 50 mm. Mounting options include Basic, FA, LB, and TC brackets. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. For strokes at or above 300 mm, verify side-load limits to prevent guide wear. Remember, the stop screw only sets the end position and does not lock the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-30
- ✓ 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 SIJ200X80-30 FAQ
Yes, the SIJ200X80-30 is discontinued. The exact drop-in replacement is the SAIJ200X80-30, which maintains the same ISO 15552 interface, 200mm bore, 80mm stroke, 30mm adjust window, and G3/4 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for 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 3204kgf at 1.0MPa. The external stop screw window is 30mm, allowing you to trim the extend stroke on-site from the 80mm maximum down to 50mm. The stop sets end position only and is not a load lock.
