The inner and outer ring raceways of deep groove ball bearings are arc-shaped deep grooves, which can withstand radial loads and biaxial axial loads. They are suitable for high-speed rotation and are one of the most widely used bearings.
The deep groove ball bearings produced by UBC adopted with vacuum degassed steel and advanced heat treatment technology. The material is more resistant to fatigue and deformation than ordinary products. The whole series are adopted with G10 grade or above rolling elements and high-quality grease. The UBC deep groove ball bearing’s tolerance is generally narrowed by 2-3μm from ISO standards and the vibration and noise level are one level stricter than ISO standards.
