Bearing Features

In terms of technical performance, the rotational speed capabilities of this series are particularly outstanding. To achieve such high speeds, the bearings underwent micron-level optimization of their raceway roughness and ball sphericity during the R&D phase, with the specific aim of minimizing operational resistance. This characteristic results in minimal temperature rise during operation, thereby effectively safeguarding surrounding plastic components and precision electronic devices.
This series finds extensive application in computer peripherals, office automation equipment, micro-motors, and fishing tackle. In office equipment, its low-noise characteristics contribute to creating a quiet working environment; conversely, in outdoor gear such as fishing tackle, its dust-resistant and corrosion-resistant design ensures that performance remains as smooth as ever, even in challenging environmental conditions.
