One, bearing installation:

Tapered roller bearings and water pump bearing installation should pay attention to the following aspects:

Slewing bearing must be installed in a dry, clean environment conditions. Should be carefully checked before installation of shaft and housing mating surface, convex shoulder face, grooves and connecting surface processing quality. All fit connection surface must be carefully cleaned and remove burrs, casting unworked surface must Ex residual sand.

Bearing installation should be preceded with gasoline or kerosene to clean and dry before use, and to ensure good lubrication, bearings generally use grease, oil lubrication can be. Lubricated with grease should be used free of impurities, oxidation, rust and extreme pressure properties of high-quality grease. Grease filling is bearing and tank volume of 30% -60%, not too much. With sealing structure of the double row tapered roller bearings and water pump bearing grease has been populated, the user can directly use, can no longer be cleaned.
