thrust ball bearings can only bear axial load

The thrust bearing is generally composed of two or more thrust washers thrust washers and several rolling body composition, generally divided into shaft thrust washer tablets and seat pieces , rolling is generally the most common type of iron or copper cage assembly into the overall quality of this type of bearing is the most common type thrust ball bearings.
Thrust ball bearing is a separate high precision bearing type bearings, shaft ring, seat ring and cage , ball component separation . Shaft ring is aligned with the axis of the ring , seat ring is compatible with the bearing hole ferrule , and the gap between the shaft ; thrust ball bearings can only bear axial load , one-way thrust ball bearings can only bear axial load in one direction , two-way thrust ball bearings can withstand axial load in both directions ; thrust ball bearings can not limit the radial displacement , low speed limits , one-way thrust ball bearings can limit the shaft and the housing of a direction of the axial displacement , two-way bearing can limit the axial displacement in both directions .
Thrust roller bearings for axial load mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . With other thrust roller bearings, such bearings lower friction coefficient , high speed, and aligning performance . 29000 -based non-stick Hydrodynamic Bearing bearing symmetrical spherical roller , can reduce the roller and the raceway at work relative sliding and roller length , diameter, roller quantity, high load capacity , usually oil lubrication, individual low speeds available greased . In the design selection , preference should be given ; 80000 Thrust cylindrical roller bearings, 90000 Thrust tapered roller bearings and thrust needle roller bearings AXK type , can withstand a one-way axial load, it is more than the axial thrust ball bearings load capacity is much greater, and rigidity, small axial space occupied . Thrust cylindrical roller bearings and thrust needle roller bearings for low speed applications , thrust tapered roller bearings speed slightly higher thrust cylindrical roller bearings.

Zhangjiagang Economic Development Zone Party Work Committee

China Ltd. , the afternoon of June 8 , the temple mound Chong and other Japanese Precision Co., Ltd. China president, who visited Zhangjiagang , Zhangjiagang City Committee, Zhangjiagang Economic Development Zone Party Work Committee , Party Secretary Liang Yibo received Yangshe  temple mound Chong and his party.
 Zhangjiagang City is located in the south bank of the Yangtze River is located in the southeast of Jiangsu Province , is a coastal economic development zone and the Yangtze River contact angle measurement Interchange two emerging industrial port city . Japan NSK Precision Co., Ltd. has built in Zhangjiagang Zhangjiagang NSK (NSK) Precision Machinery Co., Ltd. , the company mainly engaged in precision NSK bearings, precision instruments, semi-finished products and related machinery and equipment. The temple mound Chong , president of NSK Chinese president to visit Zhangjiagang Zhangjiagang mainly to inspect .
 president of  Chinese temple CNC machine tools  mound Chong welcomed the arrival of his party , and briefed them on the development of this year Zhangjiagang Economic Development Zone . Zhangjiagang City, according to  the requirements of economic transformation and upgrading , Economic Development proposed a new development plan , the focus is to develop auto parts , precision instruments , represented by the emerging equipment manufacturing industry. A wave of hope NSK Precision Machinery Co., Ltd. Zhangjiagang seize opportunities to accelerate the pace of development , has won more development opportunities , economic development zones will provide more quality services for the development and expansion of NSK

It is understood , HRB400E test seismic reinforcement steel is rolling

Tonghua Iron and Steel Group has successfully developed high-speed wire production HRB400E
November 21 , Tonghua Iron and Steel Group, Shougang Tonghua Steel new line of high-speed wire rod plant produced a total HRB400E8 mm rebar 42 99.7 tons , HRB400E8 mm rebar development and production won success.
It is understood , HRB400E test seismic reinforcement steel is rolling temperature requirements are  very strict , is a newly developed product is currently being pilot production   phase. The production is the fourth year the plant rolling, rolling is the largest number of the best one , spinning temperature for the first time dropped to 900 ℃, changing the spinning temperature is not lower than the previous record of 1000 ℃ .
In the production process of organizing high precision bearing , the plant production department and rolling rolling workshop related personnel to develop a reasonable program , repeatedly revised operating points , follow the guidance and technical personnel on-site , requiring workers reasonably controlled roller speed, to ensure open rolling Wind turbine bearing temperature , temperature and spinning into the finishing temperature , to strengthen the mill grooves , guide and guard the entrance examination , timely adjustment of the finished wire size , seismic steel products to ensure customers' dimensional accuracy requirements to ensure the quality of pruning to ensure end to end water cooling and defective parts are not all clean and trim so storage product quality to meet market and customer needs.
It is reported that the feedback from the technical center sampling data, the indicators uniformity , yield strength and tensile strength to meet quality requirements.
