  • The UC wide inner ring ball bearing uses a popular set screw locking mechanism and is suggested for industrial applications where normal loads are encountered.
  • The set screw mounting feature is ideal for reversing load applications.
  • Bearing prelubricated and ready for immediate installation.
  • The wide inner ring provides effective shaft support for a broad range of industrial applications.
  • The positive contact of the land-riding bonded nitrile seal helps protect against harmful contaminants and retains lubricant under severe operating conditions.
  • An external steel flinger provides additional protection from contamination.
  • The UC series features superfinished raceways, grade-10 balls for smooth running and low noise operation.
  • UC series wide inner ring ball bearings have spherical outside diameters for use in housings with corresponding spherical inside surfaces to compensate for shaft misalignment.
