1. Assembly process
(1)Clean the inner and outer rings, rollers and cage.
(2)Sorting outer raceway size deviation.
(3)Sorting inner raceway size deviation.
(4) optional roller for trial installation, to ensure that the bearing radial clearance and two columns of radial clearance difference between qualified.
(5)Cage assembly, combined set.
(6)Measure radial clearance, check radial clearance with stopper or instrument, ensure both sides of the roller radial clearance mutual difference requirements.
(7) check the appearance, flexibility and other requirements of the project.
(8) demagnetization, cleaning, drying or dehydration.
(9) Oiling, packaging, storage.
