Miniature Deep Groove Ball Bearing
A miniature deep groove ball bearing is a type of bearing designed for applications where space is limited and high speeds are required. These bearings are commonly used in small electric motors, appliances, and other precision machinery where smooth operation and low friction are essential. They are characterized by their small size, high rotational speeds, and ability to handle radial and axial loads.
