Tapered roller bearing with water pump shaft bearing installation should pay attention to the following aspects:

A, the installation of the bearings: The installation of the bearing should be carried out in a dry, clean environment conditions.Before installation should carefully check the shaft and the shell surface, convex shoulder of end face and groove and the connection surface machining quality.All cooperate with the surface of the connection must be carefully cleaned and remove burrs, must remove all traces of sand casting raw surface.

Bearing should be taken before installation with petrol or kerosene wash clean, dry after use, and to ensure good lubrication, bearing generally use grease, oil lubrication may be adopted.Using grease lubrication, should choose without impurities, oxidation, rust and extreme pressure properties such as high quality grease.Grease filling quantity of bearing and bearing housing volume of 30% 60%, unfavorable and overmuch.With sealing structure of double row tapered roller bearing and water pump shaft bearing has good filling grease, users can directly use, shall not be clean.

Bearing installation, it must be in the ring width on the circumference of a circle of equal pressure, to press the ring into,
