Water Pump Shaft Bearing Wb

Key Specifications/Special Features:
Provides:
WB series: Double row ball water pump spindle bearing
WR series: Single row ball and single roller water pump spindle bearing
WB C series: Double row ball water pump spindle (angular contact )
WR C series: Single row ball and single roller water pump spindle bearing (four point angular contact)
Ball and roller are all made by high chrome steel, if the shaft material is high-carbon, hardness reaches 60 to 64HRC, if the shaft material is high-chrome, hardness reaches 58 to 62HRC

Water pump bearings is a double supporting bearing with a simplified structure, which constitutes no inner ring for the two supporting bearing, groove for rolling element directly made on the shaft, the outer rings of the two bearings made to a unity and two sides of the bearing closed by rubber seals. In the condition of same loading capacity, the radial dimensions are usually smaller than those of same kind; While in the condition of same radial dimensions, the loading capacity is usually heavier. Because of its good steel capacity and easy rotation and structure, they are used by many developed countries including USA, Japan, Germany and so on.
