Reliable Integral Shaft Bearing for Water Pump in Automotive Engine

The prime objective of this work is modifying of the water pump which is used for cooling the engine in automotive. In the existing pump ball, bearing is used in which the assembly and maintenance are difficult. In order to overcome these problems, integral bearing is proposed. So it is planned to modify the existing pump to accommodate integral bearing with the purpose of reducing the assembly time and increase production. The proposed integral shaft bearing has compact in size which is developed by eminence material and have one or two rows contains with balls as well as one row of the roller. It has high reliability through a newly developed water resistant seal. This reliable bearing is three times better durability when compared with existing ball bearing. It has high load durability, highly resistant to heat load and water. The bearing with integral shaft has no inner rings while having the raceway groove directly on the shaft.
