Research and development is a package of works aimed at the gaining of new knowledge and practical application in the creation of a new article or technique.

OK-LOZA OJSC together with the leading research institutes in the area of machine building and material science, continuously conducts research and development for the purpose of improvement in the quality, reliability, and service life of bearings:
  • Development and manufacture of new types of bearings, including those in accordance with the customer’s technical requirements, bearings of original designs, with improved performance and service life;
  • Type and life cycle tests of bearings;
  • Research of bearings after operation as a part of articles;
  • Research of properties and possibilities of application of new types of steels, alloys and polymeric and ceramic materials;
  • Research of materials machinability with edge and abrasive tools, development of special tools;
  • Research of properties and methods of heat and chemical-heat treatment of materials.
