Relevant units of the industry: According to the Outline of the Twelfth Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Decision of the State Council on Accelerating the Cultivation and Development of Strategic Emerging Industries, the Ministry of Industry and Information Technology has formulated and released The “12th Five-Year Plan for New Materials Industryâ€, in which superhard materials entered the key product catalogue. At present, China's superhard material production capacity ranks in the forefront of the world, but there are still many problems in industrial development. In order to speed up industrial technology innovation, vigorously develop high-tech and high value-added intensive processing products, and continuously expand the scale of the industry. The research decided to hold the 2012 Mid-Autumn Hotel (Wuhan University Three Gorges Academic Exchange Center) on October 23-26, 2012. China Superhard Materials Technology Development Forum. The conference will publish a collection of essays for this purpose. The special edition will be selected in the National Chinese, Science and Technology and Academic Core Journal "Diamond and Abrasives Engineering". At present, there are many manuscripts, which are in the stage of reviewing and editing, and continue to welcome people from all walks of life to contribute. The relevant matters of the forum are hereby notified as follows:

Roller bearing, one of the two members of the class of rolling, or so-called antifriction, bearings (the other member of the class is the Ball Bearing). Like a ball bearing, a roller bearing has two grooved tracks, or races, but the balls are replaced by rollers. The rollers may be cylinders or truncated cones. Only radial loads (i.e., loads perpendicular to the axis of rotation) can be carried when the rollers are cylindrical, but with conical rollers both radial and thrust, or axial, loads (i.e., ones parallel to the axis of rotation) can be carried. A needle bearing has cylindrical rollers that are relatively slender and completely fill the space between the races; in many cases the inner race is dispensed with. Because there is line contact between a roller and the races, while in a ball bearing there is point contact, in a given space a roller bearing can carry a greater radial load than a ball bearing.
Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing. They are usually located at the ends of the turbine and compressor shafts and are often mounted in a housing, but separated from it by a layer of pressurized oil known as a squeeze film damper.
In many cases, instead of having a separate inner race for roller bearings, the [inner race" is an integral part of the shaft or stub shaft. This reduces complexity, weight, and build-up of concentricity tolerances. Overall, this is cost effective, but the cost of replacement or repair is likely to be higher than for separate inner races.
