Why snl 515 bearing operation is not flexible?

The operation of the snl 515 bearing is not flexible, how is this a responsibility?
The newly assembled rotary snl 515 bearing product does not run smoothly.
Check the production date of the subdivision bearing. If the time is longer and the climate is colder, it is possible that the grease in the raceway is more viscous, leading to poor operation, which is more prominent in the cold region in winter.
(2) The new assembly of rotary division snl 515 bearing products idling fluid solution: after the operation and no other abnormalities can be normal use, such as accompanied by abnormal sound, check the transport process whether there is serious trauma.

The operation of the snl 515 bearing after reassembly is not flexible
(1) exclude whether the axial clearance of the subdivided bearing cannot compensate the deformation of the snl 515 bearing due to the poor coordination between the mounting surface of the main engine and the mounting surface of the subdivided bearing.The snl 515 bearing is in the state of negative clearance, the rolling body is difficult to run in the raceway (sometimes accompanied by abnormal sound);The big and small gears are not meshed properly or there are foreign matter stuck in the big and small gears.

(2) after reassembling subdivision bearing operation is not flexible exclusion
(1) Reprocess the installation plane of the host machine to make it meet the requirements;Or use gasket filling method.
(2) Adjust the meshing clearance of the gear again as required, especially pay attention to the run-out position of the gear.
(3) Check to ensure that there is no foreign matter in the meshing position of the gears.
(4) Replace a snl bearing with slightly larger clearance.
