Miniature Angular Contact Ball Bearings

Miniature angular contact ball bearing is a kind of bearing designed for limited space and high-speed rotation requirements. The structure includes inner and outer rings, balls and cages. It adopts angular contact design and has the advantages of small size, high speed, high rigidity and long life. It is widely used in high-speed electric shafts (spindles for wood carving, stone carving, etc.), precision instruments, power tools, aircraft models and other micro-equipment, providing them with reliability and high-performance support. Miniature angular contact ball bearings are also called small bearings or miniature bearings. MONTON miniature angular contact bearings are designed for applications that require compactness, low friction and high speed precision.

The inner diameter of micro angular contact bearings or spindle bearings is between 3mm and 17mm. The spindle bearing is a single row angular contact bearing with contact angle of 15 ° (C) or 25 ° (E). They can bear radial and (in one direction) axial loads. The direction of axial load is indicated by the "V" mark on the outer ring. Micro spindle ball bearings are suitable for applications that require high precision and high load combined with high speed. micro angular contact bearings are used in many applications, such as linear transmission equipment, machine tool workpiece shafts, sanding shafts, high-speed electric shafts (wood carving, stone carving, etc.), planetary reducers, drill shafts, servo motors, drones, automated production lines, 5G base station small fans, motor production line winding, activity monitoring and control probes, precision measuring instruments such as 3D printers, aerospace, precision machine tools (equipment and grinders in machining centers), servo motors, drones, automatic production lines, 5G base station small fans, motor production line winding, activity monitoring probes, electric cylinders, and other fields.
