Customize Water Pump Bearing

Water pump bearings are used in the water pump that circulates cooling water for the 

car's engine. KDKD's bearings provide a longer service life thanks to their higher sealing 

performance and grease with excellent heat resistance and water resistance.

Water pump bearings are used in the car's water pump. A shaft appropriate to the inner

 ring is installed, and that shaft is longer than the width dimensions of the outer ring. To 

the larger-diameter side of the shaft is attached the driving pulley, while the impeller is 

attached to the small-diameter side.

Structure

Water pump bearings are sealed double-row bearings with wide spacing between the two rows of rolling elements.
There is a ball-ball type consisting of only balls and a ball-roller type consisting of a ball and a roller.
Standard products have a keyway (groove) in the center of the outside surface of the outer ring for a wire (clip) to prevent the water pump bearing from coming off.

Features

  1. The profile of stepped shafts does not damage the shaft even if a large amount of force is applied from the belt.

  2. A highly effective seal is used to prevent leakage of filled grease and prevent cooling water that leaks out from the mechanical seal from entering the bearing. Some use a highly-sealed triple-lip seal to further enhance the prevention of cooling water from entering.

  3. The grease used has excellent durability in high-speed rotation, high-temperature, and mixed-water conditions, and the sealing material used has excellent compatibility with cooling water.
