Since the 18th National Congress, economic transformation and upgrading has become a top priority, and emerging industries are undoubtedly the vanguard of transformation and upgrading. In particular, small and medium-sized enterprises and GEM companies that have already listed have opened up the M&A boom based on the capital market, forming an unprecedented peak in mergers and acquisitions. Last year, with the rapid increase in LED lighting demand, the LED industry has also ushered in an unprecedented peak of development. Enterprises in all links of the upstream, middle and lower reaches have begun to expand production, and the cloth channel has seized more market share. As one of the most convenient and efficient, M&A has been favored by LED listed companies. Since the second half of last year, almost all LED listed companies have had large and small mergers or acquisitions or various forms of strategic cooperation. Under the background of the weakening and staying of the entire LED lighting industry, listed companies with product, technology and capital advantages are accelerating their development and integration, with a view to the rapid development of the LED lighting industry and the first-mover advantage when the concentration is improved. After last year's acquisition of NVC by Sanhao Runda and Sanan Optoelectronics' acquisition of Taiwan's Yuyuan Optoelectronics, this year, Tongfang shares have invested 900 million Hong Kong dollars in Zhen Mingli, and Wei Wei shares to welcome more than 12 million LEDs on the lighting. The mergers and acquisitions of the industry took place, and the entire industry chain battle became more and more fierce, and the industry integration drama gradually culminated. The government's policy support for mergers and acquisitions is also constantly improving. Today, the China Securities Regulatory Commission issued a refinancing method for listed companies on the GEM. For the re-financing of the GEM, which is the industry's most concerned capital market, the measures stipulate that the issuance conditions for the refinancing of the GEM include the profit in the last two years; the cash dividends are implemented according to the regulations in the last two years; the asset-liability ratio at the end of the latest period is higher than 45. 6 conditions. Most of the companies listed on the GEM are emerging industries such as LEDs. They are in a high-speed growth period. If they cannot refinance for a long time, it is not conducive to the long-term development of enterprises. The director of the LED listed company believes that the LED industry is now in the integration period, and the M&A needs the support of funds. The introduction of the refinancing method can be described as timely rain. The cost performance of LED lighting products has a strong advantage, the outbreak of the lighting market is certain, this year is mainly to test whether the performance of LED companies can meet market expectations. Zhou Yi, a researcher at Huatai Securities, believes that LED companies currently have few companies with an output value of more than 1 billion yuan. How to make them bigger and stronger will require more mergers and acquisitions, restructuring, and shareholding in the LED industry.
The Thrust Roller Bearing is used to bear axial and radial joint loads as the main axial load, but the radial load should not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has a lower friction factor, higher speed and a heart regulating performance.
The rod of the 29000 type bearing is an asymmetrical spherical roller, which can reduce the relative slipping of roller and raceway in operation, and has many advantages such as long roller diameter, large diameter, large number of rollers and high load capacity. Usually, oil lubrication is used, and grease can be lubricated at some low speed. In the design and selection, it should be selected first.
The 80000 type thrust Cylindrical Roller Bearing, the 90000 type thrust cone Roller Bearing and the AXK type thrust roller Needle Bearing can withstand the uniaxial axial load, which is much larger than the thrust ball bearing's axial load capacity, and has large rigidity and occupies small axial space.
Thrust cylindrical roller bearing and thrust cone roller bearing are suitable for low rotational speed, and thrust cone roller bearing speed is slightly higher than that of thrust cylindrical roller bearing. The thrust cylindrical roller bearing is a separable bearing. It can only withstand one-way axial load and slight impact, and can restrict the axial displacement of the shaft (or shell) in one direction, so it can be used for unidirectional axial positioning. But its bearing capacity is far greater than that of the thrust ball bearing. When roller is rolling, the roller will inevitably slide on the raceway because of the different speed of the two ends of the roller. Therefore, the limit speed of this kind of bearing is lower than that of the thrust ball bearing, which is usually suitable for low speed operation.
The standard design of thrust cylindrical roller bearing adopts a metal solid cage. According to the requirements of the user, other types or materials can be used. The thrust Tapered Roller Bearing can only bear one direction axial load, which can limit the unidirectional axial displacement of the bearing, so it can be used as a one-way axial orientation. Compared with the thrust cylindrical roller bearing, the bearing capacity is large and the relative sliding is small, but the limit speed is low.
