6300 series deep groove ball bearing

The 6300 series of deep groove ball bearings are single-row bearings with deep raceway grooves on the inner and outer rings. They are capable of accommodating radial loads, as well as limited axial loads in both directions. The "6300" in the designation indicates the nominal size of the bearing, which refers to the bore diameter.
Characteristics of the 6300 series deep groove ball bearings:
Versatility: These bearings are versatile and widely used in various applications, including electric motors, automotive components, industrial machinery, pumps, and more.
Radial Load Capacity: The deep raceway grooves enable the bearings to support radial loads, which are forces acting perpendicular to the shaft's axis. They can handle both light and moderate radial loads.
Axial Load Capacity: While primarily designed for radial loads, the 6300 series bearings can also withstand limited axial loads in both directions. However, they are not as suitable for heavy axial loads compared to thrust ball bearings.
Speed and Low Friction: Deep groove ball bearings have relatively low friction due to their smooth raceway surfaces. This allows them to operate at high speeds.
Sealing Options: Depending on the specific variant, 6300 series bearings may come with various sealing options to provide protection against contaminants and retain lubrication. Common sealing options include rubber seals (RS) or metal shields (ZZ).
