The company Dr. Erich TRETTER started in 1970 in Göppingen as an agent selling high-quality technical advice and intense machine parts. The program had hydrodynamic bearings, precision machining spindles, special ball bearings and ball-bearing longitudinal guides. Very early he recognized Dr. Bertram Tretter that point ball bearing linear guides will dominate in the Automation and therefore placed his emphasis on ball-bearing components of the linear motion. For the development of the company two performance characteristics were decisive: the production of high quality standard elements, as well as customized solutions.
