Miniature bearings, also known as small bearings or micro bearings, are designed to operate in applications that require compactness, low friction, and high rotational precision. They are characterised by their small size, often with a bore diameter of less than 30mm, and precise construction. Miniature bearings can be used at high speeds and withstand moderate loads.

The main benefits of miniature bearings are that they are:

  • Low friction – They reduce friction and wear, leading to improved efficiency and extended life of the device.
  • Reduced noise + vibration – Improves the performance and reliability of the device.
  • High precision – Important in applications where accuracy is critical.
  • Lightweight – Reducing the overall weight of the device.
  • Compact – Helps to save space in a device.

Miniature bearings are available in a variety of sizes, materials, and finishes to meet the specific requirements of each application.

  • Medical devices
  • Instruments
  • Robotics
  • Aerospace
  • Tools
  • Toys 
  • Skateboards and rollerblades
  • Electronics
  • Automotive
  • Clocks
  • Application: The type of application will determine the type of bearing that is required. For example, ball bearings are typically used in applications where high speeds are required, while roller bearings are typically used in applications where high loads are required.
  • Size: The size of the bearing must be compatible with the space that is available.
  • Load capacity: The bearing must be able to support the load that will be applied to it.
  • Speed: The bearing must be able to operate at the desired speed.
  • Environment: The bearing must be able to operate in the environment in which it will be used.
