Precision 3.1 x 5 x 0.3mm Shim - Yokomo YOKZCS330  [YOKZCS330]

Compact 3.1 x 5 x 0.3mm precision shim

This Yokomo shim is a small precision spacer intended to deliver exact clearance where it counts. The 3.1 x 5 x 0.3mm designation identifies inner diameter, outer diameter, and thickness, so the part suits fine adjustments on shafts, pins, and small bearing interfaces within model drive and suspension systems.

Employ the shim to eliminate axial play, fine-tune gear mesh, or combine several shims to reach a needed cumulative thickness. In practice the shim is positioned between rotating parts or at bearing faces so the assembly attains correct running clearance without modifying primary components.

To fit, slide the shim over the shaft or locating pin until it sits flush, verify there is no binding, and check the complete range of motion. For best results, alter shim count in small increments and reassess handling or play after each change.
