Recently, it was learned from the China Rubber Industry Association that in 2015, the main economic indicators of the Chinese tire industry fell across the board, and the company's loss was as high as 20%. According to the data, in 2015, among the 40 tire companies included in the association's statistics, 31 domestic enterprises had 6 losses, the loss amounted to 447 million yuan, and 9 foreign-invested enterprises had 2 losses, with a loss of 135 million yuan. The overall loss is 20%. Shi Yifeng, secretary-general of China Rubber Association Tire Branch, said that although the prices of basic raw materials such as rubber remained low last year, tire prices continued to fall, completely offsetting the positive impact of falling raw material prices. It is reported that the domestic tire industry has shown the phenomenon of “three highs and three lows†with high inventory, high risk, high degree of homogenization, low price, low profit and low operating rate. From the main economic indicators of the China Rubber Association, we can see that in 2015, the output value of tires decreased by 14.62%, the value of export delivery decreased by 16.52%, the sales decreased by 15.37%, and the profit decline rate was as high as 22.22%. China Rubber Association data show that in 2015, the average monthly operating rate of all steel tire enterprises was about 65%, down 6% year-on-year; the average monthly operating rate of semi-steel tire enterprises was about 70%, down 10% year-on-year. However, according to Tire World Network, the operating rate of many tire companies is far from this level. In addition, due to the elimination of backward production capacity, environmental relocation and capital chain breakage, six tire companies (factories) closed or closed down in China, and nine companies' tire projects were suspended due to funding, environmental impact assessment and land issues.
Iron Shielded Deep Groove Ball Bearing is one type of ball bearings. shields are non-contact metallic (carbon or stainless steel) devices which allow high-speed operation but offer limited protection against the ingress of moisture and dirt. but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up. Iron shielded deep groove ball bearings often have steel shields installed on one or both sides and are pre-lubricated with grease. While many different retainers are available, pressed steel cages are most commonly used.
Bearing dust shields have been available almost as long as Ball Bearing itself. Shields are needed to stop the grease lubrication used in these bearings from leaking out. This is particularly important in applications where grease leakage may contaminate the product. The main impetus towards shielded bearings comes from the growing use of [sealed-for-life" bearings in items such as white goods, cars and power tools. Shields are fitted in the outer ring and do not make contact with the inner ring, but form a narrow gap with it.
Depending on the bearing design, series and size, MANU supplies shields in different designs.
With one shield (-Z) on one side or two shields (-2Z/ZZ) on both sides; Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for shields.
Celarance:
Internal clearance provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. Large clearance C3/C4 usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.
Tolerances
The standard version of our single-row deep groove ball bearings has the tolerance class P0
(designs with tighter tolerances available upon request)
To be the first class, to do the best quality, to make users satisfied, to ensure customers relieved, are our enterprise purposes. Welcome bearing dealers` and Conveyor Idler manufacturers contact from all over the world, and become our partner.
