Ball bearings with filling slot |
|
Single row deep groove ball bearings with filling slots have a filling slot in both the inner and outer ring enabling more and larger balls to be incorporated than in standard deep groove ball bearings. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots, but their axial load carrying capacity is small. They are also unable to operate at such high speeds as bearings without filling slots. Depending on the main application for which they are used, deep groove ball bearings with filling slots have a cage or no cage |
The smaller sizes, which are mainly used for automotive gearboxes and are identified by a standard designation, incorporate a cage. The standard assortment of these bearings comprises basic design open bearings, shielded bearings, bearings with a snap ring groove. |
The large-size bearings which are designed for heavily loaded, slowly rotating applications are without cage. |

The conditions concerning misalignment of the outer ring with respect to the inner ring are the same for deep groove ball bearings with filling slots as for standard bearings. However, the filling slots limit the angular misalignments to 2 to 5 minutes of arc. Any greater misalignment may lead to the balls running over the edges of the filling slot. This will cause increased bearing noise and reduced bearing service life. |
