About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-75
The AirTAC SAIJ200X75-75 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position calibration. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops during machine setup or product changeovers.
Equipped with a 40mm carbon steel rod and M36x2 threading, this unit handles substantial loads while operating at speeds of 30-500mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides for AirTAC CMSE reed and DMSE electronic switches, though this specific configuration ships without a magnet. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, and uses PT tapered port threads for pneumatic connection.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ200X75-75 Is Used
Heavy Pressing Operations
Dial in the exact 0-75mm travel distance needed for various heavy-material pressing tasks without changing out the entire cylinder setup.
Product Line Changeovers
Quickly reconfigure the end-stop position on automated assembly lines when switching between different product sizes or thicknesses.
Custom Fixture Alignment
Fine-tune the retract position during initial commissioning to perfectly align heavy 200mm bore actuators with mating tooling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-75 the Right Cylinder?
Select this 200mm bore cylinder when your process demands maximum thrust combined with variable end-stops, such as pressing or heavy clamping assemblies where the exact travel distance changes between product runs. Conversely, the 200mm bore is the largest standard SAIJ size available.
When matching an ISO 15552 replacement, verify the 75mm stroke, 75mm adjustment range, PT port threads, and the required mounting interface. Because the stroke is under 300mm, side-load concerns are reduced, but the heavy 40mm rod still requires proper guiding for long-term seal integrity. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure. For true fail-safe load holding, consider the AirTAC SAIL or BSAI series instead.
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 SAIJ200X75-75 FAQ
At the maximum rated pressure of 1.0 MPa, it delivers up to 3204 kgf of push force.
The SAIJ200X75-75 features a rear adjusting screw that allows you to shorten the 75mm nominal stroke by up to 75mm, creating a usable travel window of 0-75mm. This stopper fine-tunes the end position at commissioning but does not lock the load without live air pressure.
