Features

  • These bearings are designed to support ball screws that are used as actuators of high precision and high speed machines
  • Their stiffness is much greater than conventional angular contact ball bearings as these have a greater number of balls
  • These bearings are supplied with a pre-set preload to eliminate complicated adjustment and torque measurement
  • Flush ground bearings (suffix DU or U) can be used in DB (back to back), DF (face to face) or DT (tandem) assembly
NOTE - Load Ratings

When single flush ground bearing (suffix U) is assembled in duplex and axial load is applied to 2 rows or 3 rows, load rating listed is to be multiplied by 1.62 or 2.16 respectively for Dynamic and multiplied by 2 or 3 respectively for Axial Limiting Load.
