What is small bearing?

Miniature and small-sized ball bearing mean ball bearing, up to 30mm in external diameter. Miniature and small bearings are used for extremely high speeds. These bearings offer a low level of noise, vibration, and frictional torque performance. Miniature and extra-small ball bearings can be sealed by shields or rubber seals to prevent leakage of lubricating grease or entry of dust.

 

What are tiny ball bearings used for?

Bearing Basics applications, miniature precision bearings help reduce friction between parts that need to move independently while effectively saving space in tight applications, such as medical, instrumentation and semiconductor equipment. The balls are available in a range of sizes to meet specific project needs.

 

Where is miniature ball bearings be used? Ball bearings are the most common bearing type and can be found in many every day objects, such skateboards, blenders, bicycles, DVD players and photocopiers. Small wheel bearings are also frequently be used for window and door rollers.This type of bearing is typically used in applications which have a high speed and a low load.
