What to pay attention to before bearing installation

What to pay attention to before bearing installation
  Preparation of bearings
Because the bearings are rust-proofed and packaged, do not open the package until just before installation. In addition, the anti-rust oil coated on the bearing has good lubricating performance. For general-purpose bearings or grease-filled bearings, it can be used without cleaning.
However, for instrument bearings or bearings used for high-speed rotation, the anti-rust oil should be washed away with clean cleaning oil. At this time, the bearings are easy to rust and should not be left for a long time.
  Inspection of shafts and housings
Clean the bearing and housing to make sure there are no nicks or burrs left by machining. Absolutely no abrasives (SiC, Al2O3, etc.) molding sand, chips, etc. inside the housing. Secondly, check whether the size, shape and processing quality of the shaft and the shell are consistent with the drawings. Before installing the bearings, apply mechanical oil to each mating surface of the shaft and housing that has passed the inspection.
