Yokomo YOKZCS330 Shim 3.1 x 5 x 0.3mm for Shaft Spacing  [YOKZCS330]

Slim 3.1 x 5 x 0.3mm shim

This Yokomo shim serves as a small but important R/C component to set accurate spacing where minimal clearance is required. With dimensions of 3.1 x 5 x 0.3mm (ID x OD x thickness), it fits common shaft and pin setups and is suitable for fine tolerance work in drive and steering assemblies.

Use the shim to correct axial play, refine gear mesh, or stack several shims for precise cumulative thickness. In model assemblies the shim is typically positioned between rotating parts or at bearing interfaces to achieve the intended running clearance without changing major components.

Installation is simple: slide the shim over the shaft or locating pin until it seats, confirm free movement with no binding, and verify operation across the full travel. For tuning, make small incremental changes by adding or removing shims until the desired response is reached.
