Yokomo YOKZCRA3630 - 3x6x3mm Collar Pack, 8pcs, Red  [YOKZCRA3630]

3x6x3mm shaft collars for RC assemblies

This Yokomo YOKZCRA3630 collar pack provides eight identical 3x6x3mm collars in red, sold as a set for RC-scale accessory use. Designed as small axial spacers, these collars help control shaft endplay and maintain consistent spacing between bearings, gears, or other rotating parts in RC models.

Installation is straightforward: fit the collar onto a shaft to set axial position or to act as a visual spacer when assembling transmission or drivetrain components. Because they are supplied in an 8pcs pack, they are convenient for routine maintenance, quick replacements, or tuning sessions where multiple spacers are needed.

Practical tuning role: use the collars to fine-tune alignment and reduce unwanted lateral movement, especially when adjusting gear mesh or bearing preload. Their uniform 3x6x3mm size makes them a simple, repeatable option for incremental adjustments without changing core hardware.
