Details

Single row deep groove ball bearings with filling slots are a versatile and robust bearing option. They accommodate a greater number of balls compared to standard deep groove ball bearings, allowing for increased radial load carrying capacity. This simple, yet effective design provides reliable operation with minimal maintenance required. These bearings can accommodate radial and axial loads in both directions, though the axial load capacity is somewhat limited due to the presence of the filling slots. Despite this, single row deep groove ball bearings with filling slots are particularly versatile, offering low friction, low noise, and low vibration characteristics, which enable high rotational speeds. Their easy mounting and reduced maintenance requirements make them a popular choice across a variety of applications.
