Automobile water pump shaft bearing is a type of bearing. The cage material is usually reinforced nylon 66, and the sealing ring material is generally NBR. If you need pump bearing working at high temperature you can used stainless steel material with fluorine rubber seals.

Water pump bearings can be used in automotive parts.

MKL BEARING can produce water pump bearing used for peugeot 405,WB1630083 water pump bearing ,we also can produce WIB1630037/W2481 shaft bearings .

OEM Water Pump Bearing Materials and Parameters:

Shaft bearings are including shaft, outer ring, steel ball roller,they are produce with is bearing steel (GCr15). Because high-quality bearing steel is smelted through vacuum deoxidation, electromagnetic stirring, and has less oxide content, it can withstand greater contact pressure stress while also withstanding greater high variable tensile stress. After heat treatment, the hardness of the shaft raceway It is 58-62HRC. The hardness of the ring raceway is 60-64HRC, and the hardness of steel balls and rollers is 61-65HRC. When the shaft and outer ring are made of carburized bearing steel, the raceway hardness is 60-64HRC. The material of the cage is usually reinforced nylon 66, and the material of the sealing ring is generally nitrile rubber. When the requirements are higher, the fluorine rubber sealing ring can also be selected.

PEUGEOT 405 Water Pump Radial clearance:

When manufacturing, the shaft bearing clearance is based on the radial clearance: in the case of no special requirements and no load, the radial clearance is 15-35um, and the user reasonably chooses the matching of the outer ring and the seat hole. Surplus is very important. Excessive interference will sharply reduce the radial clearance of the bearing, destroy the bearing, and make the water pump unable to work normally. In actual work, in addition to the above reasons, it is also necessary to consider the temperature rise. The thermal expansion caused reduces the clearance, so the recommended table for general interference is as follows:

Lubrication: As the water pump shaft bearing works at high speed and high temperature, the lubrication conditions directly affect the operating life of the shaft and shaft. Usually, imported high-grade grease with higher dropping point and better consistency is used, and the sealing ring is usually also The radial contact seal with larger interference is used to ensure that the bearing does not lose oil for many years.
