Water Pump Bearing

Water Pump Bearings are specially designed double-end support shaft bearings applied to automobile engine cooling water pumps. Different from ordinary bearings, they integrate shaft, rolling elements and sealing into a single unit to support the water pump impeller. Working continuously under high temperature, coolant vapor and alternating loads, they demand excellent heat resistance and anti-leakage performance.

Premium water pump bearings adopt reinforced internal structure and special high-temperature grease. Optimized contact design lowers friction heat generation. Multiple rubber sealing lips stop cooling liquid and steam from penetrating inside to avoid rolling element rusting. These bearings fit gasoline engines, diesel engines for passenger vehicles and commercial trucks. Stable operation guarantees continuous circulation of engine coolant to control working temperature. Poor-quality bearings easily cause water pump leakage, abnormal noise and engine overheating. Strict production testing ensures long service life under harsh engine compartment environments.
