About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-20S
The AirTAC SAIJ32X100-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 80 to 100mm, allowing you to dial back the nominal 100mm stroke by up to 20mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches.
This variant uses a SUS304 stainless steel rod (code B) with an M10x1.25 thread and PT tapered port threads, making it highly suitable for environments where corrosion resistance is paramount. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and relies on the built-in variable air cushion for deceleration; it does not lock or hold the load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-20S Is Used
Changeover Calibration
Dial in the exact 80 to 100mm travel window during product size changeovers on a packaging line without replacing the cylinder.
Sensor Positioning
Leverage the dual sensor grooves and integrated magnet to mount CMSE or DMSE switches precisely along the adjusted stroke path.
End-Stop Tuning
Fine-tune the retract end position during machine commissioning using the rear screw, avoiding the need to add external mechanical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX100-20S the Right Cylinder?
Choose this 32mm bore adjustable-stroke cylinder when your application requires precise end-position tuning at commissioning or during product changeover, eliminating the need to swap out physical cylinders or bolt on external stops. If your setup requires higher force, stepping up to the 40mm bore neighbor yields 628N of push force at 0.5 MPa, but for compact assemblies needing 402N, this profile cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces. For load-holding without live air pressure, this unit is insufficient; you should explore the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
When configuring your ISO 15552 replacement, match the 32mm bore, 100mm nominal stroke, 20mm adjustment range, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. Because the stroke here is under 300mm, the 12mm rod diameter handles standard loads well without requiring an external guide.

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 Adjustable Cylinder SAIJ32 SAIJ32BX100-20S FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If operated at 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to shorten the effective travel from the 100mm nominal stroke down to 80mm. This creates an 80 to 100mm adjustable window for fine-tuning the end position at commissioning, but it functions as a stop and does not hold the load without live air.
