About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-75S
The AirTAC SAIJ200X165-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 90-165 mm, allowing you to dial back the 165 mm nominal stroke by up to 75 mm during commissioning. In the 200 mm bore class, it delivers a robust 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for heavy-duty positioning.
This unit includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and is equipped with a magnet for position sensing. It uses PT tapered port threads (G3/4) and supports a speed range of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-75S Is Used
Heavy Press Tuning
Dial in the exact 90-165 mm travel window during heavy press setup to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Rapidly adjust the retract end-position on automated lines when switching product sizes, using the 75 mm rear screw to fine-tune the stroke.
Large Assembly Jigs
Use the 15708 N push force to seat large components, relying on the rear stopper to set precise end-limits for each specific jig run.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-75S the Right Cylinder?
Step down to a 160 mm bore if your application requires less force, as that size provides 10053 N of push force at 0.5 MPa. Choose this SAIJ200X165-75-S when you need precise end-position tuning for product changeovers without swapping cylinders or adding external stops. The rear adjuster acts solely as a travel stop; it does not hold the load without live air. For load-holding without pressure, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ200AX165-75S FAQ
The rear adjuster screw lets you shorten the effective travel from the 165 mm nominal stroke by up to 75 mm, creating a 90-165 mm usable window. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N. The operating speed range for this 200 mm bore is 30-500 mm/s.
