Recently, another group of ZWZ major equipment necessary for the country bearing products successfully produced high-end, cast bronze to fill the gap: 5 MW wind turbine pitch bearing sent to the user installed; complete shield bearing main bearing and hob, etc. R & D, installed and began testing.
Successfully developed with the nature of mind and greater transfer of axial displacement of SDB bearings, bronze bushing reached world leading level; large portfolio backing, precision, sealed bearings successfully developed, through the user's acceptance of ... ...
In recent years, along with the rapid development of equipment manufacturing industry, major equipment,dry bushing supporting most of the imported high-end bearings, bearings and other core components of major equipment has become a bottleneck in the development countries. plain bearing ZWZ commitment to the national field of sixteen major technologies and equipment bearings supporting the development of domestic and industrial base construction tasks, construction of the "ZWZ precision technology and manufacturing industrial park" and "precision technology and manufacturing (Dalian) Industrial Park" ,sleeve bushing relying on independent innovation, the development of a number of high-tech products with independent intellectual property rights, to achieve a high-end bearings industrial upgrading, changing many of our key focus areas of technical equipment on the high-precision, DU bushing high reliability, high speed bearing long-term dependence import condition.
In the new energy industry, the development of a large-scale ZWZ clean and efficient power generation equipment, bearings,bushing bearing varieties of the world has already built up the largest production scale, and the supporting units of the whole, the largest wind power generation bearing production bases, in the design and development, manufacturing process , brass bushing testing the three major technology has reached the world advanced level, with the world's only 3 to 5 MW capacity wind turbine supporting bearings. ZWZ also successfully developed large-scale thermal power generating units produced a large vertical mill bearings, achieve a localization support and so on.
In the petrochemical industry, ZWZ developed a large twin-screw granulator unit supporting multiple joint before and after the thrust bearing, turntable bearing the development of deep drilling rig, Mould guide plate offshore drilling platform series bearings and mud pump bearings, chemical equipment developed and manufactured series of high reliability of maintenance-free bearings, breaking the blockade of foreign technologies bearing industry.
In the steel industry, the successful implementation of ZWZ large sheet cold rolling equipment and machining equipment for coating the localization project, developed a large domestic steel companies supporting the hot and cold rolling bearings; plasic bushing the successful development of precision sheet metal Sendzimir mill bearing, H beam vertical roller bearings; series developed a heavy plate, ship plate hot rolling mill bearings and heavy rail rolling meter series bearings.
In mining, the coal industry, ZWZ developed a large lift, large transmission, bucket wheel excavators and other equipment supporting the full range of high reliability bearings.
In shipbuilding, port machinery, marine engineering, ZWZ developed a full set of walking and lifting of the supporting bearings, developed and manufactured for the large transport ships supporting a variety of marine lifting crane turret support bearings.
In the rail transportation industry, to heavy freight line, high-speed passenger line and urban rail transit project basis, supporting the development of a comprehensive ZWZ bearing heavy goods vehicles, speed of 350 km of high-speed bearings EMU by bench; Development developed the "Harmony" high-power locomotive axle bearings and axle bearings insulation; urban rail and metro transmission and axle bearings have been put into operation.
In the machine tool industry and precision equipment industry, ZWZ large, sophisticated, high-speed CNC equipment made significant progress in the project bearing: Development of high-speed high-precision high-power milling spindle bearings, developed the largest turntable bearings table 2.5 m ; major projects for the development of automatic control systems, developed supporting joint industrial robot bearings and wheel bearings.
In the large-scale construction machinery industry, and successfully developed ZWZ quantities of electric wheel dump truck bearing mine; order to speed up large TBM and other large construction machinery research and development of the spindle bearing shield developed for the 863 projects have been driving machine testing machine support, access to experimental verification stage.
In the automotive and agricultural machinery industry, automobile industry in China ZWZ developed a series of heavy-duty card wheel hub bearings, gearbox bearings and differential bearings, strong support for the Chinese truck to become the world superpower; car third-generation wheel hub bearings realized quantities.
ZWZ sixteen countries in the development of major technologies and equipment in the field of bearing process, the idea and quickly research and development achievements in industry, breaking the monopoly of foreign technology and the blockade has created enormous social, out of a science the development of the new road.
