This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-10 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-10 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 SIJ200X80-10
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-10 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 SAIJ200X80-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-10
The AirTAC SIJ200X80-10 is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200 mm bore and 80 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 70-80 mm window. It features a 40 mm rod, M36x2 thread, G3/4 port, and 50 mm adjustable air cushions. The drop-in replacement is the SAIJ200X80-10, which preserves the exact ISO 15552 mounting interface, force, and adjust window.
Force output is substantial: 15708 N push and 15080 N pull at 0.5 MPa, scaling to 21991 N at 0.7 MPa and 28274 N at 0.9 MPa (theoretical max 3204 kgf at 1.0 MPa). For sizing, a safe working load is roughly 9425 N (about 60% of the 0.5 MPa push), translating to a vertical lift capacity of approximately 801 kg with a 2:1 margin. The SAIJ successor uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S), so it cannot accept legacy CS1-B/DS1-B sensors. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-10 Is Used
Heavy Press Tonnage Calibration
Needs field stroke tuning to dial in the exact 70-80 mm extend contact point on high-tonnage press fixtures, preventing over-travel without disassembling the tooling.
Pallet Positioning Stop
Requires adjustable end stops to accommodate varying pallet dimensions, allowing operators to trim the extend stroke by up to 10 mm on-site for precise alignment.
Large Mold Clamping
Demands exact end-position tuning to ensure large molds close completely without shock, using the external stop screw to fine-tune the final 10 mm of travel.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-10 with the SAIJ200X80-10
To replace the discontinued SIJ200X80-10, order the drop-in SAIJ200X80-10, which matches the 200 mm bore, 80 mm nominal stroke, 10 mm adjust window, G3/4 port, and ISO 15552 mounting footprint. When sizing both ways, the neighbouring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore provides 15708 N push at 0.5 MPa—choose the 200 mm if you need the 801 kg vertical lift capacity. The 10 mm adjust window is ideal for fine-tuning the extend end position within a 70-80 mm range. Mounting options include Basic, FA, LB, and TC brackets. Because this SKU has no -S magnet, it cannot support position sensing. For stroke lengths of 300 mm or greater, carefully verify side-load limits to prevent excessive guide wear. Remember that the stop screw merely sets the end position; it does not hold the load on air loss, so specify an external rod lock or pilot-operated check valve if load holding is required.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-10
- ✓ 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 SIJ200X80-10 FAQ
Yes, the AirTAC SIJ200X80-10 is discontinued. The exact drop-in replacement is the SAIJ200X80-10. It shares the same ISO 15552 interface, 200 mm bore, 80 mm stroke, 10 mm adjust window, G3/4 port, and mounting options, while adding an upgraded piston seal. The stop screw sets end position but is not a load lock; use an external rod lock for held loads.
The 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa (max 3204 kgf at 1.0 MPa). Speed is 30-500 mm/s. The 10 mm external stop screw window allows trimming the 80 mm extend stroke down to 70 mm on-site. It features a 40 mm rod, M36x2 thread, G3/4 port, and 50 mm adjustable cushions.
