Single row deep groove ball bearings with filling slots

Single row deep groove ball bearings with filling slots have a filling slot in both the inner and outer rings (fig. 1) to accommodate more balls than 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 limited. They are also unable to operate at the same high speeds as bearings without filling slots.
Deep groove ball bearings with filling slots are available open or with shields. They are also available with or without a snap ring groove. Open bearings that are also available with shields, may have recesses in the outer ring (fig. 2).
Large size deep groove ball bearings with filling slots, without cage are available on request.
