About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-20
The AirTAC SAIJ200X200-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 200 mm bore and a 750 mm stroke, yielding a usable travel window of 730 to 750 mm. This 20 mm adjustment range allows operators to dial in the exact retract end-position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration.
It uses a PT G3/4 port and a 40 mm carbon steel rod with an M36x2 thread. The variable air cushions at both ends absorb kinetic energy, but the rear adjuster acts purely as a travel stop—it does not lock or hold the load without continuous live air pressure.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-20 Is Used
Heavy Machinery Changeover
Ideal for large automated presses where the 20 mm rear stopper adjustment accommodates varying material thicknesses without re-mounting the actuator.
Large Pallet Positioning
Provides the immense thrust needed to index heavy pallets, while the adjustable end-stop fine-tunes the resting position at the conveyor end.
Assembly Station Tuning
Allows commissioning engineers to precisely set the 730-750 mm travel window during machine setup, ensuring perfect alignment for oversized components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-20 the Right Cylinder?
Select this 200 mm bore model when your application requires maximum thrust in the ISO 15552 range, as stepping down to a 160 mm bore reduces your 0.5 MPa push force to 10053 N. The SAIJ200X750-20 is chosen over a fixed-stroke SAI when a product line needs variable end-stops for quick changeovers, letting you trim the 750 mm travel back by up to 20 mm. For any load-holding requirements without live air, this cylinder is insufficient; consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) instead.
At a 750 mm stroke, the 40 mm rod and M36x2 thread provide high structural integrity, but long unsupported strokes invite deflection. An external guide mechanism is strongly recommended to prevent side-load damage. This SKU uses a PT tapered port thread and omits the -S magnet option. It supports a reduced SAIJ mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (excluding FB, CA, CB, and CR). The standard operating speed range is 30-500 mm/s.

- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-20 FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw lets you mechanically shorten the 750 mm nominal stroke by up to 20 mm, creating a 730-750 mm usable travel window. It functions as an end-position stop for tuning, not as a load-holding lock.
