The national standard "Rolling Bearing Wind Turbine Gearbox Bearing" drafted by ZWZ prescribes the code method, structure type, external dimensions, technical requirements, inspection methods, inspection rules, signs, rust prevention, packaging, transportation and storage of the main drive speed-increasing gearbox bearings for wind turbines. This standard is applicable to the production inspection and user selection and acceptance of the main drive speed-increasing gearbox bearings for wind turbine generator sets. The gearbox bearings designed by ZWZ according to this standard have been supplied to internationally renowned companies in batches.
The industry standard of "Rolling Bearing Automotive Retarder Bearings" drafted by ZWZ prescribes the code method, structure type, external dimensions, technical requirements, inspection methods, inspection rules, signs, rust prevention, packaging, transport and storage of automotive retarder bearings. The standard applies to the production, inspection and acceptance of bearings for automotive hydraulic retarders and eddy current retarders, and fills the gap in the automotive industry for bearings for automotive retarders. Bearings for retarders designed by ZWZ according to this standard have been supplied in batches for many well-known domestic automobile gearbox manufacturers.
Standards are the "commanding heights" of market competition, and standards determine competitiveness. As a member of the National Rolling Bearing Standardization Technical Committee, in recent years, ZWZ has actively participated in the formulation of national and industry standards. It has presided over the drafting and participated in the drafting of "Rolling Bearing Thrust Spherical Roller Bearings", "Rolling Bearings Railway Freight Car Bearings", and "Rolling Bearings". The formulation of 8 national standards such as "Railway Locomotive Bearings", "Rolling Bearings, Railway Passenger Car Bearings" and 12 industry standards such as "Technical Conditions of Rolling Bearing Thrust Spherical Roller Bearings", has the right to speak in the "standard circle" and has comprehensively improved core competitiveness of the Company.
