INA

Innovation in INA technology For decades, INA has represented creative solutions, representing the level of expertise in design and production, as well as representing a great focus on customer requirements.

Breaking rid of the shackles of thinking, breaking through the obstacles of traditional habits, and looking for new ways are one of the essence of corporate culture at the beginning of the company or decades later.

As early as 1946, Dr. George Schaeffler (Georg Schaeffler) and his brother Verheim (Wilhelm) co-founded the Schaeffler Company, and proved the significance of breaking the thinking framework in 1949.

At that time, his research and development of needle rollers and holder components led to a major breakthrough in the application of needle roller bearings in the industrial field, filling the gap in this field.

George Schaeffler's innovative spirit and desire to succeed became part of INA's eternal corporate culture in its 35 factories around the world.

INA develops and produces rolling bearings, sliding bearings, linear motion products and automotive engine parts throughout the world.

As a partner in research and development, INA has been working closely with customers from the initial stage of system development.

New user-specific solutions are created every day, which means that more than 1,000 new products are put on the market every year.

INA invests heavily in its R & D division, focusing specifically on the construction of new R & D centers in Germany, Asia and North America.

The INA brand is widely used in the automotive industry, including engines, gearboxes and chassis, as well as in the industrial sector.

INA has incomparable technical advantages in precision product molding and serves to provide customers with excellent cost-effective solutions.

In the industrial sector, the four industry administrations respectively guide the marketing of INA and FAG brands in the fields of production machinery, power transmission and railway, heavy industry and consumer products.
