Deep Groove Ball Bearings with Filling Slots are specifically engineered for applications requiring higher radial load-carrying capacity than standard deep groove bearings can provide. By incorporating a filling slot (loading notch) in the inner and outer rings, these bearings can be assembled with a larger number of balls. Our collection features the 200 and 300 series, often used in heavy-duty industrial gearboxes, automotive transmissions, and agricultural machinery. While they offer superior radial support, it is important to note they are designed for primary radial loads with limited axial thrust. Available in open or shielded configurations, these bearings provide a robust solution for extending service life in equipment subjected to heavy radial forces.
