Brushless motor bearing chart.

Application guide for brushless motor bearings. This is a small list of the many brushless motor applications that these can be used in. Please understand that due to many manufacturers changing designs, this is only a basic guide. We suggest measuring the bearing you are replacing before ordering.

Bearings are measured in whole sizes and can easily be measured with a simple ruler. Three dimensions are needed: thickness, Inner diameter (ID), and Outer diameter (OD)

Example sizing:
8 x 16 x 5
8mm ID (inner diameter) x 16mm OD(outside diameter) x 5mm width
