1, the installation of the bearings must be conducted 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 matching connection surface must be carefully cleaned and remove burrs, rough surface must remove all sand castings.

2, bearing should be taken before installation with petrol or kerosene wash clean, dry after use, and to ensure good lubrication, grease lubrication, commonly used bearing lubrication may be adopted.Using grease lubrication, should choose without impurities, antioxidant, anti rust, superior performance, such as extreme pressure 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. 3, bearing installation, it must be in the ring width on the circumference of a circle of equal pressure, to press the ring into, shall not be used
