Product Introduction
Automotive water pump bearings are key components that support the smooth rotation of the automotive water pump rotor. They are used in engine cooling systems to ensure coolant circulation and stable engine temperature.
Product Features
High Wear Resistance: Automotive water pump bearings are made of GCr15 bearing steel with a triple tempering process, resulting in 15% higher fatigue strength than similar products and a service life exceeding 80,000 kilometers.
Precision Machining: Inner and outer rings and ball bearings have tolerances ≤0.02mm. CNC machined surfaces ensure smooth rotation and low friction.
Reliable Sealing: Double-layer sealing (fluororubber + stainless steel cover) provides waterproof and dustproof protection, reducing the risk of coolant leakage.
