Weima Electric (Shanghai) Ltd.

RENK AG’s beginnings go back to 1873, when Johann Julius Renk founded a small machining workshop for the mechanical production of gear wheels in Augsburg’s Lechviertel. In 1879, the young company moved to the Göggingen neighborhood, where RENK’s headquarters are still located today. The company was converted into a joint-stock company in 1897, and RENK has been part of what is now the MAN Group since 1923.

RENK also became part of the Volkswagen Group when Volkswagen AG acquired a majority stake in MAN SE in 2011. Today, RENK has a global outlook as a leading supplier of high-quality drive technology for a wide range of applications. The company’s branches in Augsburg, Rheine, and Hanover are its major production locations.

RENK’s products and services are consistently tailored to the needs of our customers. Absolute precision, commitment, and speed are the basic prerequisites for efficiency and the capacity to act, especially in sensitive business areas. This commitment to the highest quality standards is what sets apart each and every subsidiary and company in the RENK Group around the world. Their flexibility, willingness to cooperate, and technical understanding enable them to communicate with customers and provide systems advice as partners. RENK has been defining standards and what is technically possible for many years in four strategic business units.

RENK slide bearings are manufactured by RENK AG Hannover Plant, in which the main types of bearings for motors are EF Series, EM Series, ER/EG Series and ZM Series.
