Miniature angular contact ball Bearings also known as small bearings or micro bearings,MONTON Miniature angular
contact ball bearings are designed to operate in applications that require compactness, low friction, and high rotational
precision. Miniature angular Contact or Spindle bearings fall between 3mm inner diameteand 25mm inner diameter.
Spindle bearings are single-row angular contact bearings with a nominal contact angle of 15° (C) or 25° (E). They can
be subjected to both radial and (in one direction) axial loads. The direction of the axial load is shown by a “V” marking
on the outer ring. Miniature spindle ball bearings are suitable for applications requiring precision while carrying high load
combined with high speed.
Miniature bearings are used in many applications, such as Linear transmission equipment,Machine tool workpiece shaft
and grinding wheel shaft,High speed electric shaft (wood carving, stone carving, etc.),Planetary reducer,Drill head shaft,
Servo motor, drone, automatic production line,5G base station small fan, motor production line winding, activity monitoring
Control probe Precision Measuring Instruments 3D Printer ,Aerospace etc.

Miniature angular contact bearings are critical components in high-speed and high-precision applications. Their design
and working principles enable them to handle both axial and radial loads. Depending upon the bearing material specified,
they have excellent performance characteristics in harsh environments.
The choice of material and design of the bearing determine the load capacity and speed rating of the bearing. With their
small size and high load capacity, miniature angular contact bearings play a crucial role in many industrial and medical
applications.
