This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-20TC — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-20TC 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 SIJ200X80-20TC
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20TC 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 SAIJ200X80-20TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20TC
The AirTAC SIJ200X80-20TC is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 60-80 mm stroke from the 80 mm nominal maximum. The stop sets the end position but is not a load lock; drift occurs on air loss. This 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa via its G3/4 port.
The exact drop-in replacement is the SAIJ200X80-20TC, matching the bore, force, adjust window, and TC mounting. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. A computed buyer insight: safe working load is ~9425 N (60% of the 0.5 MPa push), allowing a ~801 kg vertical lift with a 2:1 margin. Note this non-magnetic SKU cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-20TC 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 SAIJ200X80-20TC 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 SIJ200X80-20TC Is Used
Press Stroke Tuning
Trimming the extend stroke by up to 20 mm on-site allows precise positioning of large pressing tools without re-machining stops.
Heavy Load Lowering
The 200 mm bore provides 15708 N push @0.5 MPa to lower heavy assemblies, with the external screw setting the exact resting height.
Mold Positioning
Using the TC mount for pivoting, this cylinder adjusts mold closure limits on-site, accommodating varying part thicknesses within the 60-80 mm window.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-20TC with the SAIJ200X80-20TC
To replace the discontinued SIJ200X80-20TC, order the drop-in SAIJ200X80-20TC. To size both ways, the neighboring 160 mm bore yields 10053 N push @0.5 MPa, while the 200 mm bore offers 21991 N push @0.7 MPa. The 20 mm adjust window is ideal for precise extend stops without machining. The included TC mount provides a trunnion interface for pivoting. Because this SKU lacks the -S magnet, it cannot accept a sensor; for sensing, select an SAIJ-S model and use legacy CS1-B/DS1-B switches. For stroke lengths >=300 mm, verify side-load guidance to prevent rod binding. The 50 mm cushions decelerate heavy 3204 kgf loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-20TC
- ✓ 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 SIJ200X80-20TC FAQ
Yes, the SIJ200X80-20TC is discontinued. The exact drop-in replacement is the SAIJ200X80-20TC, offering the same ISO 15552 interface, 200 mm bore, 80 mm stroke, 20 mm adjust window, G3/4 port, and TC mount. The SAIJ features an upgraded piston seal for longer life.
The 200 mm bore delivers 15708 N push / 15080 N pull @0.5 MPa, 21991 N push @0.7 MPa, 28274 N push @0.9 MPa, and a 3204 kgf max @1.0 MPa. The external stop screw trims the extend stroke by up to 20 mm (usable 60-80 mm). The stop sets end position and is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
