💡 What are the benefits of shielded bearings over sealed ones?
Shielded bearings like the 311KDD are great when you need protection from large particles or debris, but still want lower friction than rubber-sealed options. They’re often preferred for electric motors, HVAC, or applications where speed and moderate protection are more important than water or fine-dust sealing.
