Is there any difference between miniature ball bearings and miniature bearings?

There are some differences and connections between Miniatureature ball bearings and Miniatureature bearings:
Miniature Ball Bearings:
Structure: Composed of inner ring, outer ring, a set of balls, and cage.
Rolling element: Use spherical rolling element (ball).
Application: Widely used in situations that require high precision and low friction, such as medical equipment, electronic devices, aerospace devices, automobiles, hobbies, and remote control models.
Advantages: Low friction, suitable for high rotational speeds, low noise, and good load-bearing capacity.
Miniatureature Bearings:
Definition: Broadly speaking, it refers to all smaller bearings, including ball bearings, needle roller bearings, sliding bearings, etc.
Type:
Micro ball bearings: bearings that use balls as rolling elements, as mentioned earlier.
Miniature needle bearings: bearings that use needles as rolling elements and are suitable for bearing high radial loads.
Miniatureature Sleeves Bearings: Without rolling elements, they rely on sliding friction to operate and are typically used in low-speed, light load applications.
Miniatureature Thrust Bearings: Specially designed to withstand axial loads, they can be ball or needle roller types.
Application: Due to the variety of types, micro bearings can be applied in various different situations, and suitable types can be selected according to specific needs.
Main differences:
Scope: Micro ball bearing is a type of micro bearing that specifically refers to bearings that use balls as rolling elements. Micro bearings are a broader category that includes various types of small-sized bearings.
Application characteristics: Micro ball bearings are particularly suitable for high-speed and high-precision applications due to their low friction and high precision. Other types of micro bearings are suitable for different working conditions and load requirements based on their design characteristics.
