Thai Industry Minister Chakramont Pasukavanich said recently that the Thai government has proposed support for the construction of rubber processing plant projects, including foreign investors invited at the end of 2014. At present, eight Chinese tire companies are interested, and three of them have been approved by the Investment Promotion Committee Office. The total investment reached 269 million baht.
It is inferred that investors will apply for the construction of a tire factory, with an estimated production capacity of 2.2 million pieces per year. At present, Thailand's domestic glue consumption is 560,000 tons/year, and in 2016 it will reach 1 million tons/year, accounting for 25% of the national production capacity of 4.6 million tons.
According to the project, in order to support the development of the rubber industry, Thailand Industrial Development Zone, Thailand Industrial Park and other related institutions have prepared to establish rubber city. At present, the rubber city has been set up in the area of ​​the Songkhla area of ​​the special economic zone Kanchanavanich Road, with a total area of ​​about 1800 rai.
Compared to other rolling-element bearings, Slewing Bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
A slewing bearing or slewing ring is a rotational Rolling-Element Bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill.
Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.
Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.
