  Product Description

  The NTN 5308 C3 is a double row angular contact ball bearing designed to carry combined radial and axial loads in both directions. The double row construction provides:

  • Higher load capacity than a single row bearing of the same size
  • Increased rigidity and better support for overhung loads

  Because of its C3 internal clearance, this bearing is well suited for:

  • Applications with higher operating speeds
  • Fits with interference on shaft and/or housing
  • Conditions where internal temperatures may increase during operation

  The open design with a steel cage ensures good lubricant flow and stable guidance of the balls, making it suitable for general industrial and power transmission applications.

  Typical Applications

  • Electric motors and large pumps
  • Gearboxes and reducers
  • Industrial machinery with combined radial and axial loads
  • Conveyors, fans, and drive systems
