In 2019, the company participated in the scientific and technological project achievement exhibition

        On October 26 and 27, 2019, our company, as a strategic partner enterprise of Industrial Technology Research Institute of Zhengzhou University, specially invited to participate in the achievement exhibition of major scientific and technological projects held in Henan, China.

The identification of national science and technology small and medium-sized enterprises

　　The project management office of the technology innovation fund for science and technology smes of henan province published the list of the enterprises to be put into the database for class A science and technology smes of henan province in 2018,and henan zhongzheng company successfully passed the identification.

Zhengzhou engineering technology research center

　　Driver development strategy for further implementation of innovation,promoting the construction of city development platform,according to the"zhengzhou city science and technology on organization to declare the 2018 annual zhengzhou engineering technology research center and the key laboratory of notice requirements,through the supporting institution to declare,recommended by the competent department,in the form of review,expert review,field investigation,the municipal technology bureau DangZuHui research assessment,the public,our company was rated as zhengzhou precision bearing cage with high performance composite materials engineering technology research center.

Henan zhongzheng precision bearing co., LTD. Fire drill report

　　In order to further strengthen enterprise employee fire safety consciousness,improve resilience against the emergency,able to quickly organized security evacuation,to master the correct use of fire extinguishers and method of escape,the company in 2019 at 9 a.m.on June 25,according to the requirements of the relevant"fire emergency plan",the company wide playground,and invited the leadership of the company related experts on hand to guide,hundreds of thousands of workers took part in the fire drill. When the alarm sounded, the safety supervisor immediately organized the employees to follow the evacuation route in an orderly manner, quickly evacuated the scene and arrived at the designated safe place. This fire drill is divided into three stages. The first stage is emergency evacuation, the second stage is fire fighting and the third stage is casualty treatment. 　　In order to ensure the maneuverability of the emergency plan,effectively improve the fire safety skills of the employees,the fire fighting skills,drills,key events is a fire extinguisher use and fire-fighting operation,work in play,in the fire drill,prepared by the designated personnel with good tinder the lighting,each master using a fire extinguisher,and to extinguish the fire in the fastest time,early exercise some worker in front of the fire combustion,obvious nervous and rusty,with the deepening of the practice,everyone gradually,into the fire drill in an orderly way.The whole exercise lasted more than two hours,and on-site assessment. 　　Through this fire drill,the employees of the company have improved their ability to deal with emergencies,enhanced their awareness of fire safety,and mastered the operation and use of common fire-fighting equipment.During the exercise,the sense of collective honor of the department was sublimated,and the organizational ability,command ability and strain capacity of the company's safety work leading group were also exercised. 　　Through this fire drill,and further to strengthen the enterprise staff's safety consciousness,test the feasibility of fire plan,maneuverability,familiar with the emergency rescue process,the emergency command,played a role in promoting coordination and disposal ability,high efficiency in the future,in order to carry out the safety in production work laid a solid foundation.

Free combination pairing of SKF angular contact ball bearings

Arbitrarily matched bearings are specially manufactured so that when arranged arbitrarily and mounted close together, a certain internal clearance or preload and/or uniform load distribution can be obtained without the use of spacers or the like. Any paired bearing with a model suffix indicates internal clearance (CA, CB, CC) or preload (GA, GB, GC). When ordering, you need to specify the number of individual bearings required, not the number of bearing sets. When the load capacity of a single-row bearing is insufficient, use a paired installation (series configuration); or when the load is a composite load or an axial load acting in both directions, use a paired installation (back-to-back and face-to-face pairing). The load lines are parallel when arranged in series, and the radial and axial loads are evenly shared by the bearings. However, the bearing set can only withstand axial loads acting in one direction. If the axial load acts in the opposite direction, or if there is a composite load, a third bearing that is adjusted relative to the series matched bearing must be added. The load lines of the back-to-back matched bearings are separated from the bearing shaft. It can withstand axial loads acting in both directions, but the load in each direction can only be absorbed by one bearing. Back-to-back mounted bearings provide a relatively rigid bearing configuration and can withstand overturning moments. The load lines of the face-to-face matched bearings converge toward the bearing shaft. It can withstand axial loads acting in both directions, but the load in each direction can only be absorbed by one bearing. This configuration is not as rigid as back-to-back pairing and is not well suited to withstand overturning moments. Universally matched bearings also have advantages when used in conjunction with a single bearing. Most bearings are SKF Explorer series, so they have higher precision, load capacity and higher speed.
