About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-10S
The AirTAC SAIJ32X650-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 650mm nominal stroke that can be fine-tuned down by up to 10mm, creating a precise 640-650mm usable travel window. This built-in adjustability allows you to dial in the exact retract end-position at commissioning without adding external stops.
This model includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and comes with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 porting for this 32mm bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-10S Is Used
Machine Setup Commissioning
Dial in the exact 640-650mm retract position during initial machine build, avoiding the need to machine custom spacer blocks for the end stop.
Product Changeover Lines
Quickly adjust the end-of-stroke position by up to 10mm when running a slightly different pallet size, minimizing downtime between production batches.
Sensor Calibration Rigs
Leverage the integrated magnet and CMSE/DMSE sensor compatibility alongside the 10mm stroke adjustment to fine-tune part detection routines.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX650-10S the Right Cylinder?
Choose this 32mm bore when an application requires 402N push force at 0.5 MPa with a long 650mm stroke that needs exact end-position tuning. If your setup requires higher thrust, stepping up to the 40mm bore yields 628N at the same pressure. Because the 650mm stroke is long relative to the 12mm rod diameter, an external guide is strongly recommended to prevent excessive side-loading and rod deflection.
The rear adjuster on this SAIJ cylinder acts purely as a mechanical stop to set the deceleration point; it does not lock or hold the load without continuous live air. For load-holding requirements without air pressure, consider the SAIL or BSAI series. This cylinder is dimensionally interchangeable per ISO 15552 and uses the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

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 SAIJ32AX650-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm from the 650mm nominal length, providing a 640-650mm travel window. It functions as a mechanical stop to set the end position and does not hold the load without live air pressure.
