Miniature Ball Bearings

This is a dedicated website for Small Bearings, we have small bearings starting from 1mm inner diameter, please find downhere the miniature ball bearings categorized by the bore of each size, minaiture bearings are used in miniature rc, fishing reel, miniature slot car and thousands of other miniature applications, miniature bearings can be made of carbon steel, chrome steel or stainless steel. Thousands of miniature applications, as small as a spinning ring and high precision watches to as big (still miniature) as radio control cars and trucks.

Our small bearings main function is to minimize any friction caused by any relative movement of two or more objects, in order to reach the maximum efficiency of energy usage, we aim to minimize the "converted to heat" energy.
A great variety of types and designs are known, the manifolds of the bearings is justified by their various purpose of application, each type of bearing has a certain characteristic technical properties, rolling bearings have the following advantages compared with the plain bearings:

  • Low starting moment.
  • Low friction at all speeds.
  • Low energy consumption.
  • High reliability.
  • Small width.
  • Low consumption of lubricant.
  • Long relubrication intervals.
  • Easy to mount and dismount.
  • Standardized dimensions.
