Deep Groove Ball Bearings - Miniature bearings

 

Miniature bearings are suitable for products that require high speed, low friction torque, low vibration, and low noise, and are bearings with a wide range of applications. Miniature bearings are suitable for all kinds of industrial equipment, small rotary motors, etc.; Recently, there has been an increase in demand for these devices to be miniaturized, lightweight, and thin-walled.

　　In the miniature bearings with ultra-small bore diameter, there are 18 kinds of miniature bearings with an inner diameter of φ2mm or less in the metric 68, 69 and 60 series, and 6 kinds in the inch R series.

　　Miniature bearings are suitable for all kinds of industrial equipment, small rotary motors, etc.; Recently, there has been an increase in demand for these devices to be miniaturized, lightweight, and thin-walled.

　　Main uses: office equipment, micro motors, soft drives, pressure rotors, dental drills, hard disk motors, stepper motors, video recorder magnetic drums, toy models, computer fans, encoders.

 

How can we ensure the stable operation of micro bearings in use?

1. The bearing clearance should be appropriate, too large will produce impact, too small will cause poor lubrication, which may cause tile burning;

2. The surface quality and geometry of bearings and journals should be strictly guaranteed;

3. Improve the lubrication quality of bearings, control the pressure, temperature and flow of oil, and strengthen oil filtration;

4. the use of fuel and lubricating oil in accordance with the regulations.

Reason for invalidation

 

Approximately 40% of failed miniature deep groove ball bearings are caused by contamination by dust, dirt, debris and corrosion. Contamination is often caused by incorrect use and poor use environment, and it can also cause problems with torque and noise. Miniature bearing failures caused by environmental and pollution are preventable and can be identified by simple visual observation. As long as they are properly used and installed, corrosion of miniature bearings can be easily avoided. Ablation is characterized by indentations on the raceways of the miniature bearing rings due to shock loads or incorrect installation. Ablation usually occurs when the load exceeds the yield limit of the material. Erosion can also occur if it is not installed correctly and a load crosses the miniature ring. The pressure pits on the miniature bearing rings also generate noise, vibration and additional torque.
