3x8x1mm Collar Spacer Set - 4pcs Yokomo YOKZCA3810B  [YOKZCA3810B]

Thin collar spacer for tuning axial play

The Yokomo YOKZCA3810B is offered as a set of four small collar spacers that fall under the general category of shims, collars, washers, and spacers for R/C models. The 3x8x1mm measurement provides a concise dimension for tuning axial spacing on shafts and axles.

Practical uses include dialing out small axial movement, shimming components to achieve the correct preload, and filling narrow gaps where a minimal-thickness collar is required. These collars help maintain consistent spacing where matching diameters are used.

To install, place the collar on the shaft at the required position, reinstall nearby bearings or fasteners to your chassis specification, and rotate the assembly to confirm there is no binding. For tuning, adjust in small increments and re-evaluate rotating clearance to preserve component longevity.
