Tapered Roller Bearing Belongs To Separate Bearing, And The Inner And Outer Rings Of The Bearing Have Tapered Raceways. This Type Of Bearing Is Divided Into Single Row, Double Row And Four Row Tapered Roller Bearings According To The Number Of Rows Of Rollers Installed. Single Row Tapered Roller Bearings Can Withstand Radial Load And Axial Load In A Single Direction. When The Bearing Bears Radial Load, An Axial Component Will Be Generated, So Another Bearing That Can Bear The Axial Force In The Opposite Direction Is Needed To Balance

Tapered Roller Bearings Are Mainly Used To Bear The Combined Radial And Axial Load Dominated By Radial Load. Compared With Angular Contact Ball Bearing, The Bearing Capacity Is Large And The Limit Speed Is Low. Tapered Roller Bearing Can Bear Axial Load In One Direction And Limit Axial Displacement Of Shaft Or Shell In One Direction

Type GCR  Is A Roller Type Freewheel Non-Bearing Supported. Bearings Are Required To Support Axial And Radial Loads. Lubrication And Sealing Must Also Be Provided By The Installation. Nominal Outside Diameter Is A Standard Ball Bearing Dimension.

A Typical Arrangement Is To Install This Type Beside A Bearing With The Same Housing Diameter Tolerance.

The Inner Race Is Keyed To The Shaft. The Outer Race Has A H6 Tolerance And Should Be Fitted In A Housing With A K7 Tolerance. Additional Side Notches Provide For Positive Torque Transmission.

If The Housing Tolerance Is To R6, Use Of The Notches Is Not Necessary, But The Housing Must Be Strong Enough To Not Expand After Assembly.
