About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-75
The AirTAC SAIJ200X290-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 75 mm of travel reduction. This creates a highly flexible 215-290 mm usable stroke window, allowing you to dial in the exact retract position during commissioning without swapping out the actuator.
This 200 mm bore actuator uses a G3/4 PT port and a robust 40 mm carbon steel rod with an M36x2 thread to handle substantial side loads. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE electronic switches. It utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard actuators.

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 SAIJ200X290-75 Is Used
Heavy Press Tuning
Fine-tune the 215-290 mm retract position on a large assembly press to accommodate varying material thicknesses without machining new stopper blocks.
Pallet Changeover
Adjust the rear stopper by up to 75 mm to handle different pallet sizes on a heavy-duty transfer line, drastically reducing machine setup time.
Large Mold Positioning
Dial in the exact end-of-stroke location for a 200 mm bore molding operation, using the 40 mm carbon steel rod to manage high side-loading forces.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X290-75 the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers on large machinery, letting you reset the retract end-stop quickly. If you need to hold a load vertically without live air pressure, note that the rear adjuster on this SAIJ acts only as a travel stop, not a brake; you should instead select an SAIL pneumatic lock or an external rod lock.
Because the 290 mm stroke exceeds the 300 mm threshold requiring external guidance, plan to support the load with an external guide rail to prevent excessive bending moments on the 40 mm rod. For fixed-position applications that never require end-tuning, a standard SAI cylinder offers the same ISO 15552 mounting footprint without the adjustment hardware. This configuration uses PT tapered ports, a carbon steel rod, and no magnet for sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ 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 SAIJ200X290-75 FAQ
At the maximum pressure of 1.0 MPa, it can generate up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 290 mm nominal stroke by up to 75 mm, providing a usable travel window of 215 to 290 mm. It only sets the end position and does not lock the load without live air pressure.
