If you use a hammer to install the bearing when installing the bearing, or install the bearing by pressing the inner ring of the bearing when installing the bearing into the bearing housing, it will cause one side of the bearing鈥檚 raceway damage. Noise is generated when the vehicle is driving, and when the wheels are off the ground, there is no obvious noise due to the side with a better raceway. Correct installation operation is the key to long bearing life. 4.Product pictures 5.Front wheel hub bearings model list BEARING NO.DIMENSION mmMassSeal YNR branddDBCkg銆€ DAC255200206255220.620.60.19A DAC255200206A255220.620.60.19A DAC25520037255237370.31C DAC25720043257243430.88C DAC27600050276050500.56C DAC28580042285842420.47C DAC28610042286142420.56D DAC30600037306037370.42C DAC306003373060.0337370.42C DAC30640042306442420.49C 630374/C4306521210.27A DAC34620037346237370.41C DAC34640037346437370.43B DAC34660037346637370.5C DAC35640037356437370.41B DAC35650035356535350.4C DAC35660032356632320.42C 6.Production Flow and Quality Control 7.Packing (1) Single white box per bearing, then carton box, plywood pallet.
