Deep groove ball bearings(GB/T276-1994)

Brief introduction of Deep groove ball bearing (GB/T276-1994)

It is used in rolling mill drive end as a secondary bearing with four-row cylindrical roller bearings.It decided the position of the housing relative to the roller to ensure dynamic and static axial position accurate and non interference in the maze. Rolling mill when nostrict positioning accuracy,smaller axial force can also be used as a locating bearing. As a secondary location bearing,it is generally use larger groups (C3) radial clearance. To avoid withstanding radial force, outer diameter of bearings and bearing clearance should be left.
