3x6x3mm Collar Set for Shaft Spacing - Yokomo YOKZCRA3630, 8 Red Pieces  [YOKZCRA3630]

3x6x3mm Collar Set for Precise Shaft Spacing

The Yokomo YOKZCRA3630 pack contains eight matching 3x6x3mm collars in red, intended as compact axial spacers for RC assemblies. These collars maintain consistent clearance between rotating components such as bearings and gears, helping to prevent endplay and misalignment.

Fitting is simple: slide a collar onto the shaft to lock an axial position or to act as a spacer during assembly of transmission or drivetrain parts. The 8pcs quantity makes the set handy for periodic servicing, quick swaps, or when multiple identical spacers are required.

Tuning tip: employ these collars when small, repeatable changes are needed to adjust mesh or bearing preload. Their consistent 3x6x3mm dimensions mean you can rely on predictable spacing without swapping core components.
