About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-75
The AirTAC SAIJ200X165-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 165 mm travel by up to 75 mm. This yields a usable end-position window of 90-165 mm, enabling precise fine-tuning at commissioning without swapping the cylinder or adding external stops. It delivers substantial thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa.
This unit features an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts purely as a travel stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-75 Is Used
Heavy Press Toning
Dial in the exact 90-165 mm travel window during setup to apply 15708 N of pressing force without over-traveling or damaging the workpiece.
Product Line Changeover
Rapidly shift the rear stopper up to 75 mm when switching product sizes on the line, eliminating the need to physically swap out the entire cylinder.
Variable End-Stop Positioning
Use the rear adjuster to tune the retract end-position on the fly for heavy-duty automated assembly equipment requiring precise deceleration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-75 the Right Cylinder?
Choose this 200 mm bore when your application requires maximum force in the standard SAIJ range, as stepping down to a 160 mm bore drops the 0.5 MPa push thrust to 10053 N. The 75 mm adjustment range is ideal for machinery requiring variable end-stops during product-size changeovers. For operations needing true load-holding without continuous air pressure, this cylinder is insufficient since the adjuster is not a lock; consider an AirTAC SAIL or BSAI series instead.
This model is dimensionally interchangeable per ISO 15552. Your exact configuration includes a 165 mm stroke, 75 mm adjustment, PT G3/4 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet. Because the stroke is under 300 mm, side-load stress is manageable, but always ensure the load is guided to protect the 40 mm rod and M36x2 thread from excessive lateral forces.
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 SAIJ200AX165-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 165 mm down to as little as 90 mm, creating a 90-165 mm usable window. It functions as an external stop for end-position tuning and does not lock the load without live air.
