4pc 3x8x1mm Collar Spacers for Alignment - Yokomo YOKZCA3810B  [YOKZCA3810B]

Spacer for alignment and clearance control

The Yokomo YOKZCA3810B is a 4-piece set of collar spacers included in the general R/C shim/collar/washer/spacer category. The 3x8x1mm sizing named in the product title gives a simple reference for technicians and hobbyists arranging shafts and wheel hubs.

These collars are used to limit axial movement, close slight gaps, and maintain predictable spacing where minimal thickness is required. When installed correctly they contribute to steady alignment and help reduce lateral play in matched-diameter assemblies.

Fit the collar by sliding it onto the shaft or axle at the chosen spot, secure adjacent bearings and fasteners to the chassis specification, then inspect rotation for any interference. Routine checks during tuning help ensure components are not over-tightened and can run freely.
