About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-20S
The AirTAC SAIJ32X95-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. Based on the 95mm nominal stroke and the 20mm adjustment code, this SKU provides a usable travel window of 75-95mm, letting you dial in the exact retract distance without adding external stops. It delivers 402N of push force at 0.5 MPa and utilizes a PT tapered port thread paired with a SUS304 stainless steel rod for superior corrosion resistance.
This adjustable-stroke model uses an external screw at the rear cap to act as a travel stop for precise commissioning and product changeovers. It supports AirTAC CMSE reed and DMSE solid-state sensors via the integrated dual-side barrel grooves. The mounting interface is dimensionally interchangeable per ISO 15552 and offers a specific subset of brackets: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-20S Is Used
Machine Setup Calibration
Dial in the exact 75-95mm travel distance during initial commissioning to perfectly align picking heads without swapping physical hardware.
Product Size Changeovers
Quickly adjust the retract stop on packaging lines when running different container sizes, using the rear screw to shift the end position by up to 20mm.
Light Assembly Positioning
Position small electronic components accurately, relying on the 402N push force and the fine-tuning capability to prevent overtravel damage.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-20S the Right Cylinder?
Select this 32mm bore when your application requires a compact actuator with an adjustable end-position, delivering 402N push and 345N pull at 0.5 MPa. If your setup needs greater force, stepping up to the 40mm bore increases the push force to 628N. The adjustable stroke is ideal for machine setups requiring a variable end-stop, whereas a fixed SAI cylinder is better suited for rigid, unchanging travel limits. Keep in mind that the rear adjuster and air cushion only decelerate the travel end; they do not hold the load without live air. For true fail-safe load holding, consider an external rod lock, pilot-operated check valve, or the AirTAC SAIL or BSAI series. Because the 95mm stroke is under 300mm, side-load stress is minimal, though the 12mm rod and M10x1.25 thread handle standard loads well. To match this exact configuration, specify: 32mm bore, 95mm stroke, 20mm adjustment, PT ports, SUS304 (B) rod material, and the -S magnet.

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 SAIJ32BX95-20S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 95mm down to 75mm. It allows precise end-position tuning at commissioning without replacing the cylinder, providing a 20mm adjustment window.
At a 0.5 MPa operating pressure, this double-acting cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82kgf.
