Yokomo YOKZCS305 - Shim 3.1 x 5 x 0.05mm  [YOKZCS305]

Shim for precision spacing

This RC-scale shim is sized at 3.1 x 5 x 0.05mm as indicated in the product name, intended as a thin spacer for fine clearance adjustments in model assemblies. Use it where small, repeatable thickness increments are needed to set bearing preload, align gear mesh, or correct shaft endplay without machining parts.

Installation is straightforward: place the shim on the shaft or mating surface before assembling the adjacent component, confirm stack thickness with feeler gauges or a caliper if available, then tighten fasteners to the required torque while avoiding crush of the shim. Multiple shims can be stacked to reach intermediate values; clean contact surfaces to prevent trapped debris affecting the measured clearance.

As a generic accessory, this shim is suitable for general R/C locations such as axle interfaces, gearbox stacks, servo horn seating, and bearing endplay adjustments. It is sold as a small-format precision spacer and should be treated as a fragile thin part during handling and storage.
