Market breakthrough | The first hydraulic pump bearing development project of the coupling was successfully delivered
Recently, Shanghai United Rolling Bearing Co., Ltd. (hereinafter referred to as "Coupling"), a subsidiary of Shanghai Jiyou, delivered new hydraulic pump supporting bearings to Shanghai Electric Hydraulic and Pneumatic Co., Ltd. (hereinafter referred to as "Electric Hydraulic"), also a subsidiary of Shanghai Electric Group, and successfully passed the The first round of installation tests realizes import substitution.
Since May 2023, Coupling has cooperated with Electro-Hydraulics to carry out a research and development project for heavy-duty long-life series bearings supporting new hydraulic pumps. The project mainly includes three non-standard bearings, which are located in the main shaft support system of the hydraulic pump. They need to meet requirements such as high efficiency, energy saving and environmental protection, high reliability, and long life to ensure stable operation under heavy load conditions.
In this cooperation, relying on Shanghai Electric's internal supporting advantages, the two parties have in-depth collaboration and formed a synergy. Relying on its technical strength and innovation capabilities in the field of rolling bearings, Coupling provides one-stop bearing solutions to help electro-hydraulic optimize the internal design of products to ensure that bearing products meet the needs in terms of wear resistance, stability and other performance indicators. And relying on the complete experimental machine testing system, the first round of sample accelerated fatigue testing was completed to escort the installation testing of electro-hydraulic products.
The delivery of this heavy-duty, long-life hydraulic pump supporting bearing project is not only a successful case of Shanghai Electric's internal supporting, but also marks a breakthrough in couplings in the hydraulic pump market, setting the stage for further expansion of hydraulic products and its downstream engineering machinery bearings. The supporting market has created conditions.
