6300 Series

Single-row deep groove ball bearings are a typical structural type among rolling bearings. The raceways on both the inner and outer rings are circular arcs, with a cross-sectional radius slightly larger than the ball radius. The 6300 series are medium-to-large standard types, featuring larger outer diameters and widths compared to the 6200 series, with significantly improved load-carrying capacity, making them suitable for medium and above load conditions. In addition to open types, bearings with steel shield plates or with snap rings on the outer diameter of the outer ring are also available. They generally use pressed steel cages. For large-sized bearings or those used in high-speed rotation, machined brass cages are adopted.

Features

  • Higher load-carrying capacity than the 6200 series, suitable for medium-load applications.
  • Outstanding radial load capacity, while also capable of supporting certain bidirectional axial loads.
  • Complete size series with a wide selection range.
  • Sealed types and snap-ring types accommodate different mounting requirements.
Application Examples
With low friction torque, they are ideal for medium-load, high-speed, and low-noise applications. Industrial motors, gearboxes, pump equipment, agricultural machinery (harvesters, seeders), woodworking machinery, conveyor belt rollers, blowers, air compressors, and more.
