Shaft bearing manufacturers share what should be paid attention to how to install the water pump shaft bearing.

Before the bearing is installed, it should be cleaned with gasoline or kerosene, and used after drying, and ensure good lubrication. The bearing is generally lubricated with grease or oil. When grease lubrication is used, greases with excellent performance such as no impurities, anti-oxidation, anti-rust and extreme pressure should be selected. The amount of grease filled is 30%-60% of the volume of the bearing and the bearing box, and should not be too much. The double-row tapered roller bearing with sealed structure and the water pump shaft bearing have been filled with grease, and the user can use it directly without cleaning.

If installed in large quantities, hydraulic presses can be used. When pressing in, ensure that the end face of the outer ring and the shoulder end face of the housing, and the end face of the inner ring and the shaft shoulder end

When the bearing is installed, an equal pressure must be applied to the circumference of the end face of the ring to press the ring in. It is not allowed to directly knock the end face of the bearing with a tool such as a head to avoid damage to the bearing. In the case of small interference, the end face of the bearing ring can be pressed with a sleeve at room temperature, and the sleeve can be beaten with a shovel, and the ring can be pressed in evenly through the sleeve.

The installation of the bearing must be carried out under dry and clean environmental conditions. Before installation, carefully check the processing quality of the mating surface of the shaft and the housing, the end surface of the shoulder, the groove and the connecting surface. All mating and connecting surfaces must be carefully cleaned and burrs removed, and the casting sand must be removed from the unadded surface of the casting.

The above is a brief introduction to the installation of the water pump shaft bearing and the points that should be paid attention to. I hope it will be helpful to you.
