6313 C3-NTN Ball Bearing 65x140x33

6313 C3 - NTN Deep Groove Ball Bearing 65x140x33

Deep groove ball bearings are one of the most common style of ball bearings which support axial forces in both directions as well as radial forces. The bearing has a single row of balls retained in a cage. This style of bearing you are viewing is what we call open style (no seals or shields), allowing the lubricant to flow around the bearing freely. Open bearings tend to be used in applications like gearboxes.
