If you're going to wholesale cheap ev bearing housing made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Overview
The EV Bearing Housing is a critical structural component used in new energy vehicle (NEV) electric drive systems, including electric drive assemblies, reducer systems, e-axles, and transmission systems.
It is used to install and support bearing assemblies, providing precise positioning and structural support for motor shafts, gear shafts, and transmission components. The dimensional accuracy, coaxiality, rigidity, and thermal performance of the bearing housing directly affect NVH performance, transmission efficiency, and vehicle reliability.
With the rapid development of high-speed and high-power-density electric drivetrains, EV bearing housings require extremely high machining accuracy and material performance.
With over 40 years of precision casting and machining experience, Sangroove (Jiangsu) Machinery Co., Ltd. specializes in manufacturing EV motor housings, bearing housings, reducer housings, and core structural components for global NEV OEM and Tier 1 suppliers.
