Abstract:
Composite bearings and methods for manufacturing these bearings are provided in which a lining comprising polytetrafluoroethylene fiber and a second fiberous material are disposed within a polymeric matrix comprising polytetrafluoroethylene particles and a wetting agent. The composite bearings may be useful in hydropower applications where self-lubricating bearings containing graphite are undesirable because graphite can be corrosive to carbon steel.

Abstract:
A sliding layer for a multi-layer bearing material that is free of lead. The sliding layer can include PTFE, sphalerite, and solid lubricants. The solid lubricants can include graphite and antimony oxide. In some embodiments, the sliding layer includes from 70 to 89 vol % PTFE, from 10 to 20 vol % sphalerite, and from 1 to 10 vol % solid lubricant (for example, graphite and antimony oxide).
"China and the US should build a new security framework in the Asia-Pacific, make breakthroughs in bilateral military relations, which lag behind their political and economic ties, and open new realms of cooperation, such as cybersafety and global governance," said Yuan Peng, a researcher of US stud
The Xi-Obama meeting itself is significant as the role of the countries' leaders is critical in keeping Sino-US relations on track, especially in setting the tone in critical times, Yuan Peng, the deputy director of the China Institutes of Contemporary International Relations, told the Global Times.
"The assertive moves by the US may cause potential military tensions between China and the US," said Yuan Peng, an expert of American studies at the China Institutes of Contemporary International Relations.
ashington's high-profile engagement has actually affected Sino-US relations. But it is not in the interest of both countries to lock bilateral ties in a standstill. So we can see the Americans now have cooler heads to deal with the South China Sea issue," Yuan Peng, Niu's colleague, told China Daily.
