This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAIJ200X75-75S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAIJ200X75-75S 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 SIJ200X75-75S
The AirTAC Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAIJ200X75-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-75S
The AirTAC SIJ200X75-75S is a discontinued double-acting single-rod ISO 15552 adjustable-stroke cylinder with a 200mm bore and 75mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 0-75mm extend window. It delivers 15708N push and 15080N pull at 0.5MPa, features a 40mm rod with an M36x2 thread, adjustable 50mm cushions, a G3/4 port, and operates at 30-500mm/s. The exact drop-in replacement is the SAIJ200X75-75S, sharing the same interface, force, and mounting.
The stop screw sets the end position but is not a load lock; the cylinder drifts on air loss. For safe sizing, target a working load around 9425N (60% of the 0.5MPa push) or roughly 801kg for vertical lifts with a 2:1 margin. The SAIJ successor retains the ISO 15552 mounting footprint for hardware reuse and upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ200X75-75S 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 SAIJ200X75-75S 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 SIJ200X75-75S Is Used
Press Fit Tuning
Allows operators to fine-tune the extend stroke by up to 75mm on-site to accommodate varying insert depths without changing the cylinder.
Variable Position Diverter
Adjusts the extend endpoint precisely to meet changing product sizes on a packaging line, using the external stop to set the exact push distance.
Adjustable Stop Gate
Sets a physical end position for pallets or heavy loads, trimming the 75mm stroke as needed to adapt to different pallet dimensions.
Replacing the Airtac SIJ200 Double Rod Adjustable Cylinder SIJ200X75-75S with the SAIJ200X75-75S
To replace the discontinued SIJ200X75-75S, order the drop-in SAIJ200X75-75S, reusing your existing FA, LB, or TC mounts via the ISO 15552 interface. If downsizing, the 160mm bore yields 10053N push at 0.5MPa; if upsizing is required, confirm from datasheet as 200mm is the largest standard option. The 75mm adjust window is ideal when exact extend endpoints vary by up to 75mm. The -S magnet supports legacy CS1-B/DS1-B switches, while the SAIJ uses current AirTAC switches. Because the nominal stroke is 75mm, side-load concerns are minimal, but always verify guide alignment. Remember the stop screw is not a lock; for held loads use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ200X75-75S
- ✓ 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 SIJ200X75-75S FAQ
Yes, the SIJ200X75-75S is discontinued. The exact drop-in replacement is the SAIJ200X75-75S. It shares the same ISO 15552 interface, 200mm bore, 75mm stroke, 75mm adjust window, G3/4 port, and mounting options, but features an upgraded piston seal.
It delivers 15708N push and 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and 28274N at 0.9MPa, with a theoretical max of 3204kgf at 1.0MPa. The external stop screw provides a 75mm adjust window, shortening the extend stroke from the 75mm maximum down to 0mm. The stop sets end position and is not a load lock.
