B1022E Motor-use Deep Groove Ball Bearings with Optimized Sound Output

Product catalog summary

Overview: The document discusses the optimization of the inner raceway surface of motor-use deep groove ball bearings using 3D analysis technology. The focus is on reducing sound output in the frequency range unpleasant to the human ear (1,000 Hz–5,000 Hz).

Specifications: The bearings are designed for use in motors of household appliances and industrial machinery, particularly in environments where noise reduction is critical. The optimization involves smoothing the surface in the rolling direction (circumferential direction) to enhance performance.

Sound Optimization: The new development aims to reduce sound output in the 1,000–5,000 Hz frequency band, which is typically unpleasant to human ears. This is achieved through the optimized design of the inner raceway surface.

Product Features: The bearings are available with various options such as shielding plates and seals. The document includes a comparison of the sound output between conventional and improved bearings, highlighting the reduction in loudness.

Technical Data: The document provides detailed specifications including inner diameter, outer diameter, width, basic rated load (Cr, C0r), and permissible rotational speed for grease and oil lubrication. These specifications are crucial for selecting the appropriate bearing for specific applications.
