What Is a Water Pump Bearing?
Water pump shaft bearing The steel used for the conventional shaft bearing (including shaft, outer ring, ball roller) is high carbon chromium bearing steel (GCr15).
Water pump shaft bearing
Right!
- Chinese name
- Water pump shaft bearing
- Steel
- High carbon chromium bearing steel

- 60-64HRC
- Material of sealing ring
- Nitrile rubber
- Water pump shaft bearing The steel used for the conventional shaft bearing (including shaft, outer ring, ball roller) is high carbon chromium bearing steel (GCr15).
- Because high-quality bearing steel is smelted through vacuum deoxidation, electromagnetic stirring, and less oxide content, it can withstand larger contact compressive stress while also bearing large high variable tensile stress. After heat treatment, the shaft raceway hardness It is 58-62HRC. Outer ring raceway hardness is 60-64HRC, steel ball and roller hardness 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. The material of the seal ring is generally NBR. When the requirements are high, a fluorine rubber seal ring can also be used.
- 1. Cause of improper operation? Improper installation, operation or disassembly may cause deformation or defect of the cage
- 2. Reasons for insufficient lubrication? Inadequate or improper lubrication may cause component abrasion or serious deformation of INA imported bearings.
- 3. Reasons for rust and corrosion? Contact with water may cause the water pump shaft and the inlet bearing components to be damaged and rusted. Imported bearings after rust damage may cause spalling during operation
- 4. Current cause? Energizing while turning may cause grooves or nicks. When the imported bearing is stationary? Improper grounding of the electrical operation will cause slight burns
- 5. Causes of external materials? Abrasive particle pollution and debris intrusion may cause wear, abrasion and dents of the imported bearing working surface
- 6. Cause of eccentricity? Eccentricity, tilt or excessive load may cause geometric stress concentration or surface peeling
