About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-50S
The AirTAC SAIJ32X500-50-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 500mm nominal stroke that can be fine-tuned down by up to 50mm, creating a precise 450-500mm usable travel window. This built-in adjustability allows you to dial in the retract end-position during commissioning without swapping out the cylinder or adding external stops.
This model features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the G1/8 port matches the 32mm bore standard. It supports a speed range of 30-800mm/s and utilizes adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-50S Is Used
Product Changeovers
Quickly dial in the 450-500mm retract distance when switching between product sizes on a packaging line without changing cylinder hardware.
End-Position Tuning
Fine-tune the exact end-stop during machine commissioning to absorb mechanical tolerances and achieve perfect alignment.
Sensor-Driven Sorting
Leverage the integrated magnet with DMSE electronic sensors to confirm stroke endpoints in automated sorting gates.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX500-50S the Right Cylinder?
Choose this 32mm bore when you need 402N push force (345N pull) at 0.5 MPa with on-the-fly end-position tuning; if your application requires less force, stepping down is not an option in this size range, but stepping up to a 40mm bore yields 628N. The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder locks you into one exact dimension. Because the stroke is 500mm, the 12mm rod diameter requires external guiding to prevent excessive side-loading on the piston.
When specifying an ISO 15552 replacement, match the 32mm bore, 500mm stroke, 50mm adjustment range, PT tapered port threads, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop and the air cushions only provide deceleration—neither will hold a load without live air pressure. For positive load-holding, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX500-50S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm, providing a usable travel window of 450-500mm. It acts as a mechanical stop to set the exact retract position but does not lock the load without continuous air pressure.
