This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X80-40 — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X80-40 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 SIJ200X80-40
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-40 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 SAIJ200X80-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-40
The AirTAC SIJ200X80-40 is a double-acting single-rod ISO 15552 adjustable-stroke cylinder, now discontinued and superseded by the drop-in SAIJ200X80-40. It uses an external stop screw to trim the extend stroke by up to 40 mm on-site, yielding a usable 40-80 mm extend window from the 80 mm nominal maximum. Equipped with a 50 mm adjustable air cushion at each end, a Ø40 mm rod, and a G3/4 port, it delivers 15708 N push and 15080 N pull at 0.5 MPa.
The SAIJ replacement retains the exact ISO 15552 mounting interface and introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Computed buyer insight: a safe working load is roughly 9425 N (60% of the 0.5 MPa push force), supporting a vertical lift of about 801 kg with a 2:1 margin. Note this non-magnetic SKU cannot accept a switch, and the stop screw sets end position but does not lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X80-40 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 SAIJ200X80-40 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 SIJ200X80-40 Is Used
Heavy Press Tonnage Calibration
Needs field stroke tuning to set precise bottom-dead-center on a 200 mm bore press, trimming the extend stroke up to 40 mm to accommodate different material thicknesses.
Large Mold Positioning
Requires adjustable end-positioning for heavy industrial molds, using the 80 mm nominal stroke and external stop screw to dial in exact contact without reprogramming the motion controller.
Oversized Pallet Diverter
Demands on-site extend stroke adjustment to deflect oversized pallets on a high-force conveyor, leveraging the 15708 N push at 0.5 MPa to redirect loads reliably.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X80-40 with the SAIJ200X80-40
To replace the discontinued SIJ200X80-40, order the drop-in SAIJ200X80-40, matching the 200 mm bore, 80 mm stroke, 40 mm adjust window, and G3/4 port. When sizing both ways, the neighboring 160 mm bore yields 10053 N push at 0.5 MPa, while the 200 mm bore provides 21991 N push at 0.7 MPa. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 40 and 80 mm. Mounting options include Basic, FA, LB, and TC. This SKU lacks the -S magnet and cannot support legacy CS1-B/DS1-B sensors. For stroke lengths of 300 mm or greater, verify side-load limits to prevent excessive rod wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X80-40
- ✓ 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 SIJ200X80-40 FAQ
Yes, the SIJ200X80-40 is discontinued. The exact drop-in replacement is the SAIJ200X80-40, which shares the same ISO 15552 interface, 200 mm bore, 80 mm stroke, 40 mm adjust window, and G3/4 port. The SAIJ family also features an upgraded piston seal for longer life.
The SIJ200X80-40 delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. The external stop screw provides a 40 mm adjustment window, allowing the extend stroke to be shortened from the 80 mm nominal maximum down to 40 mm on-site. The stop sets end position and is not a load lock.
