About Dr. TRETTER
Dr. Erich Tretter, Maschinenelemente GmbH + Co. is a family-owned manufacturer, importer and engineering partner for linear technology headquartered in Rechberghausen with around 70 employees. The product range covers profile rail guides, round and roller guides, ball bushings and torque ball bushings, steel shafts, ball screw and trapezoidal screw drives, linear units, ball rollers and tolerance rings. In its own production, profile rail guides, guide shafts and screw drives are machined to drawing; torque shafts are cut to length, end-machined and supplied in hardened, ground or hard-chrome-plated versions. Materials used include in particular Cf53, 100Cr6, C60, X90CrMoV18 and 1.4112 for shafts as well as 1.4301 for tolerance rings, which are formed by cold rolling of strip material. Customers include over 4,000 companies worldwide, among them special machinery builders, medical technology companies, metrology and testing specialists, automotive suppliers, automation specialists, jig and fixture builders and maintenance providers. Via its trading partners Dr. TRETTER AG in Beringen (Switzerland) and Beham Techn. Handels GmbH in Austria as well as authorized NSK representation, the company supplies customers internationally.
