9 SMPZ JSC (9 СМПЗ)

JSC "9 SMPZ" is a full-cycle enterprise producing large-size bearings. The plant's founding date is considered to be 18 March 1942, when the first bearing 7522 was produced for the legendary T-34 tank. Before corporatization in 1992, the plant was called the "9th State Bearing Plant named after V.V. Kuibyshev (9 GPZ)". On 16 October 1992, the enterprise was transformed into OJSC "Samara Bearing Plant". In 2022, the production shops and equipment got a new life. After coming under the management of METALLSERVICE company, restoration of production of large-size and extra-large-size bearings began. On 18 March 2023, the plant received its new name – JSC "9 SMPZ". In 2024, the first batch of large-size bearings was produced. The plant's own heat-treatment shop allows complex thermal and chemical-thermal treatment of parts, such as carburizing, cyaniding, hardening, tempering, HFC, etc. The shop is equipped with various heating furnaces, cooling baths (oil, air), and other auxiliary equipment. Production of large bearing rings is carried out on high-precision machines ensuring the required geometry and dimensional accuracy. The process includes a number of stages, from preparation of the blank to finishing the finished product. Mechanical processing (turning, milling, grinding), welding, heat treatment. The use of CNC for manufacturing rolling elements allows achieving high accuracy and quality, as well as automating the production process. 100% process and inter-operational control of each product is performed.
