Research institute DIGITIMES Research counts the revenue of the world's major LED packaging plants in the first half of 2017. Among them, Nichia is still ranked first, and its optical semiconductor business unit revenue reached 132.79 billion yen (about 1.14 billion US dollars), which is a big lead. The second place in the industry; the three LED packaging plants in the mainland revenue growth of more than 50 research institutions DIGITIMES Research statistics in the first half of 2017 global major LED packaging plant revenue, of which, Nichia is still ranked first, its optical semiconductor business unit It received a total of 132.79 billion yen (about 1.14 billion US dollars), which is a big leader in the second place. The three LED packaging factories in mainland China have revenue growth of more than 50%, which is better than other countries. Comparison of 1H16 and 1H17 revenues of major LED packaging factories in the world Comparison of the top LED packaging plants in the world in the first half of 2017: Luchang grew more than 50% Note: 1. The revenue is relatively uniform during the Western calendar period. 2. Osram's revenue from semiconductor semiconductors has been deducted from internal purchases; Lumens, Everlight and Lunda's total revenue (including lighting). In the first half of 2017, the industry with more than $400 million in revenue, followed by Nichia, Osram, Seoul Semiconductor, Yiguang, and Mulinsen, first appeared in the group as mainlanders (Mulinsen). Mulinsen is actively developing upstream and downstream of the LED supply chain to expand the competitiveness of packaging products. In terms of the growth rate of the first half of 2017, the mainland LED packaging and testing industry continued to maintain rapid growth. Mulinsen, Honglizhihui and Guoxing Optoelectronics grew more than 50% compared with the same period of last year. In the mainland, packaging companies continue to expand production capacity, and those outside the mainland have adjusted their product layout to avoid price competition. Among European and American players, Osram's revenue grew by 11.1%, Cree's decline by 11.2%; Japanese plant Nichia's small growth of 4.9%, Toyota's synthetic decline by 26.7%; Korean factory Seoul Semiconductor's growth rate of 12.1%, LG Innotek and Lumens The respective declines were 4.1% and 5.6% respectively; Taiwan's Yiguang and Ronda declined by 2.8% and 11.7% respectively.

Spherical Bearings are radial Plain Bearings consisting of an outer ring and an inner ring made of bearing steel and with spherical sliding contact surface. These bearings are suitable for arrangements with heavy radial load at low misalignment and oscilation. Furthermore the bearings can carry specific axial load in both directions.
Design specifications
Main dimensions
Main dimensions of spherical bearings are in accordance with the international standards ISO 6124/1.
Designation
Designation of standard spherical bearings is specified in the dimension tables and consists of type designation and dimension. Non-standard designation (radial clearance, sealing, dimension differences) are designated according to the standard STN 02 04608.
