Compared With Single-row Cylindrical Roller Bearings Of The Same Radial Dimensions, This Type Of Bearing Can Be Subject To Larger Radial Load. The Bearing Is Characterized In Compact Structure And Small Deformation When Being Subject To Load, So It Is Very Applicable For Bearing Of Machine Tool Shaft. NN…K Type: The Structure Is The Same With NN Type Bearing, But The Internal Bore Is Conical, Which Facilitates The Minim Adjustment Of The Radial Windage And Mounting And Dismounting. Most Of The Machine Tool Shafts Adopt This Type Of Bearing. The Bearing Is Mounted On The Conical Shaft, And The Radial Windage Is Adjusted By The Press-in Amount Of The Inner Race. NNU Type, NNU…K Type: The Outer Race Is Provided With Rib, While The Inner Race Is Not Provided With Rib. This Type Of Bearing Can Be Divided Into Two Types, Namely The Bearing With Cylindrical Bore And The One With Conical Bore.
