Yokomo YOKZCRA3620 3x6x2mm Collar Spacer Set 8pc Red  [YOKZCRA3620]

3x6x2mm Precision Collar Set

This Yokomo YOKZCRA3620 collar set offers a compact spacer option for R/C models that need 3x6x2mm collars. The pack contains 8 pcs in red, sized for cases where a thin collar or shim sits between hubs, bearings, or rotating shafts to control lateral position or clearances on model drivetrains and wheel assemblies.

Intended use is straightforward: fit the collar onto the shaft or into a bore that matches the 3x6x2mm dimensions, then check axial position and running clearance under load. The part serves as an accessory-level component for fine tuning wheel offset, correcting small misalignments, or replacing worn collars during maintenance and setup.

Installation notes: confirm the shaft diameter and mating bore accept a 3x6x2mm collar, slide the collar into place, and secure with the original retaining method such as a set screw, clip, or hub fastener. When adjusting spacing, proceed incrementally and recheck drivetrain alignment and wheel runout after each change.
