Quantity:


Miniature ball bearings are a type of small-sized ball bearings designed to handle light loads and operate in compact spaces. They are commonly used in applications where space is limited and low-friction, precise movement is required. Despite their small size, miniature ball bearings offer reliable performance and are essential components in various industries and devices.
