1. Handling of bearings

1. General remarks
 
a) Bearings are highly precise products. Handle carefully to keep them free from dirt and dust as well as from impact.
b) Use suitable handling jigs.
c) Keep bearings away from moisture or perspiration to prevent corrosion.
2. Storing
  Bearings are treated to prevent corrosion at the time of shipment. If they are stored unused for a long period of time, place on a shelf more than 30cm high from the floor, at 65% or less humidity and at 20. Keep them away from the strong sun. Do not place them near the window, where moisture condensation is likely.
3. Pre-installation preparations
  Do not clean off anti-corrosion oil on the bearing when it is used under normal conditions. When it is used in an application of extremely high precision or at high speed, remove anti-corrosion oil with unpolluted cleaning oil, assemble quickly, and inject lubricant.
4. Inspection of shaft and housing
  Before assembly, inspect the shaft and housing, and apply machine oil or other appropriate material to the mating surfaces of the individual components.
