Import Automotive Water Pump Bearing — Buy in Bulk from Supplier in China

The Automotive Water Pump Bearing from Zhenjiang Zhongjian Bearing Co., Ltd is a deep-groove ball bearing designed specifically for the high-speed, high-load conditions of automotive water pumps. It features a single-row design with a steel cage, enabling it to support both radial and axial loads while maintaining low friction. The bearing is pre-lubricated with a high-temperature grease suitable for continuous operation at speeds up to 10,000 RPM, typical for water pump applications.

Manufactured from chrome steel (SAE 52100 or equivalent), the bearing offers high hardness and wear resistance, which are critical for withstanding the dynamic stresses in a water pump assembly. The inner and outer rings are precision-ground to ensure smooth rotation and minimal runout, while the sealing solution typically includes a contact rubber seal on one or both sides to prevent contaminant ingress. This design aligns with standard automotive bearing specifications for durability and performance.

This bearing is primarily used in passenger cars, light trucks, and machinery requiring reliable coolant circulation. It is sourced by water pump manufacturers, automotive repair shops, and OEM suppliers. Packaging is typically in bulk boxes or individual polybags for smaller orders. Buyers should confirm the exact bearing code, load ratings, and sealing type with Zhenjiang Zhongjian Bearing Co., Ltd to ensure compatibility with their application.
