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

Compact 3x6x3mm Shaft Spacers in Red

The Yokomo YOKZCRA3630 set supplies eight red 3x6x3mm collars intended as small axial spacers for RC model assemblies. These collars help preserve consistent spacing between bearings, gears, and other rotating parts to reduce unwanted movement.

To use, position the collar on the shaft to establish the desired axial location or to serve as a simple visual spacer when putting together drivetrain or transmission components. The eight-piece pack is convenient for carrying extras or replacing multiple spacers during tune-ups.

Setup advice: try the collars when you need a repeatable increment for alignment or to trim bearing preload. Their identical 3x6x3mm profile gives predictable results when making minor adjustments without modifying primary hardware.
