This series of deep groove ball bearings strikes an optimal balance between compact design and reliable performance, capable of accommodating a wide range of shaft diameters. Classified as an equal-section thin-wall bearing series, its cross-sectional dimensions remain relatively constant as the bearing size increases—a feature that offers significant convenience to engineers when designing standardized product lines.
Bearing Features
The internal raceways undergo precision grinding and are paired with high-precision steel balls, resulting in minimal vibration and extremely low noise levels during operation, thereby meeting the stringent requirements for quiet environments demanded by high-end equipment. Despite its lightweight and thin-profile design, the series is engineered with an optimized combination of ball diameter and raceway curvature, enabling it to effectively withstand both radial loads and bidirectional axial loads. It is widely utilized in applications such as stepper motors, drone motors, bicycle bottom brackets, various precision encoders, small cooling fans, and a diverse array of automated control devices.
