Auto Water Pump Bearing

Description Characteristics 1.Good water resistance: due to long-term contact with the coolant, it must have good water corrosion resistance. 2. High temperature resistance: It can maintain stable performance under high temperature working environment of engine. 3. Low noise: The noise generated during operation is small, ensuring a quiet environment in the car. 4. High reliability: Ensure long-term stable operation and reduce the probability of failure. Classification 1.Ball bearing: composed of inner ring, outer ring, ball and cage, with high carrying capacity and speed. 2. Needle roller bearing: Needle roller is slender, suitable for occasions with limited space and high bearing capacity requirements. Basic Parameters 1.Size specifications: including inner diameter, outer diameter and width, according to the design of different models of water pump. 2. Rated dynamic load and rated static load: reflects the bearing capacity. 3. Limit speed: indicates the highest speed at which the bearing can operate safely. The Working Principle When the automobile engine is running, the pump shaft is rotated by the belt, and the pump bearing supports the pump shaft and reduces friction. The pum
