About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-10S
The AirTAC SAIJ100X165-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 155 to 165 mm. It delivers a robust 5497 N of push force at 0.7 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet enables precise end-position detection with AirTAC CMSE reed or DMSE electronic solid-state switches.
This model incorporates a SUS420J2 stainless steel rod (option A) for enhanced durability against moisture and minor side loads, paired with a substantial M20x1.5 rod thread. The rear adjustment screw acts purely as a mechanical stop to trim the retract end-position during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, a SAIL or BSAI variant is recommended instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-10S Is Used
Product Changeover Adjustment
Dial in the exact 155 to 165 mm retract position during machine format changeovers without installing external stopper blocks or replacing the cylinder.
Heavy-Duty Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy jigs or fixtures into a precise working area, using the rear screw for final calibration.
Assembly Line Timing
Fine-tune the end-of-stroke timing on automated assembly presses where slight variations in component height require a 10 mm travel correction.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust—such as the 5497 N generated at 0.7 MPa—and the ability to fine-tune the end-stop by up to 10 mm without swapping hardware. If your force requirements are lower, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa, whereas moving up to a 125 mm bore provides 8590 N. The adjustable stroke is ideal for product changeovers on a line where exact end-positioning varies slightly.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 165 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR. Because the 165 mm stroke is relatively moderate for this bore, side-load risks are minimal, but an external guide remains advisable for heavy lateral loads.

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 SAIJ100 Adjustable Cylinder SAIJ100AX165-10S FAQ
At a 0.7 MPa operating pressure, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. At 0.5 MPa, it provides 3927 N of push force.
The rear adjuster screw allows you to shorten the effective nominal 165 mm stroke by up to 10 mm, creating a 155 to 165 mm usable travel window. It functions as a mechanical stop for end-position tuning and does not hold the load without live air.
