About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-75S
The AirTAC SAIJ200X750-75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control. It features a rear mechanical stopper that allows you to fine-tune the effective travel window down to 675 mm from a 750 mm nominal stroke without external shims.
This adjustable-stroke design simplifies product changeovers by letting technicians dial in the retract end-position at the machine. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU carries the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection. It uses PT tapered port threads (G3/4) and relies on a 50 mm air cushion at both ends to decelerate the massive 3204 kgf maximum load.

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 SAIJ200X750-75S Is Used
Heavy Press Tuning
Dial in the exact 675-750 mm end position during heavy press commissioning without swapping cylinders or adding external mechanical stops.
Large-Product Changeover
Adjust the retract distance on the fly to accommodate varying widths of large materials moving down an assembly line.
Actuator Calibration
Use the 75 mm rear stopper window to precisely calibrate the resting position of heavy actuators in automated welding fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-75S the Right Cylinder?
The 75 mm adjustment range is specifically valuable for large-format machinery where you need precise end-stop tuning during commissioning or when accommodating varying product sizes on the same line.
For any stroke length of 750 mm, the unsupported mass of the 40 mm rod and heavy load demands an external guide to prevent side-loading damage, as the rod alone cannot suspend cantilevered weights. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. If your setup requires fail-safe load holding, you must integrate an external rod lock or select the AirTAC SAIL or BSAI series. This cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X750-75S FAQ
The maximum thrust is 3204 kgf at 1.0 MPa. The operational speed range for this bore size is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the 750 mm nominal stroke by up to 75 mm, creating a usable travel window of 675 to 750 mm. This stopper only sets the end position and relies on the 50 mm air cushion for deceleration; it does not lock or hold the load without continuous air pressure.
