About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-75
The AirTAC SAIJ200X200-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 15708N push force and 15080N pull force at 0.5 MPa, making it suited for heavy-duty positioning. By turning the rear stopper screw, technicians can fine-tune the effective travel window down from the 200mm nominal stroke to anywhere between 125mm and 200mm without adding external physical stops.
This model uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Because the adjuster acts strictly as a travel stop and not a locking device, the cylinder cannot hold a load without live air pressure; true load-holding requires a SAIL or BSAI series cylinder.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-75 Is Used
Heavy Press Tuning
Dial in the exact 125 to 200mm travel distance during heavy press commissioning to accommodate varying material thicknesses without swapping out the entire actuator.
Product Changeover
Rapidly adjust the retract end-position on a production line when switching between product sizes, leveraging the 75mm trim range for fast machinery setup.
Variable End Stops
Replace fixed external stopper blocks with the integrated rear screw on the assembly line, allowing operators to fine-tune the stroke endpoint dynamically during operation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-75 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when an application requires up to 3204kgf of maximum thrust at 1.0 MPa alongside variable end-position tuning. If the 75mm adjustment window is excessive or the 15708N force at 0.5 MPa is too high, stepping down to the 160mm bore provides 10053N of push force. The PT tapered port thread matches the G3/4 air supply requirement for this bore size. Mounting choices are limited to the standard SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles. For any stroke length of 300mm or more, an external guide is recommended to support side loads, though this 200mm stroke unit handles its 40mm rod thread and M36x2 thread size robustly.
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 SAIJ200AX200-75 FAQ
At 0.5 MPa it provides 15708N of push force and 15080N of pull force, reaching a maximum of 3204kgf at 1.0 MPa. The operational speed range for this 200mm bore is 30-500 mm/s.
The rear stopper screw allows you to shorten the effective travel from the 200mm nominal stroke down to a minimum of 125mm. This creates a 125-200mm adjustable window for fine-tuning the end position at commissioning without changing the cylinder itself.
