Sulfur dioxide emissions are the main cause of atmospheric pollution and acid rain. In recent years, the state has promulgated a series of laws and regulations to promote the control of sulfur dioxide emissions from thermal power plants. It is estimated that in the next 10 years, about 300 million kilowatts of thermal power installed flue gas desulfurization equipment will be put into operation and construction in China, with nearly 10 million kilowatts in our province alone. The unit needs to be loaded with this environmentally friendly device.
Hunan Jiaqing Environmental Protection Equipment Co., Ltd. seized this market opportunity and actively carried out technical exchanges and cooperation with leading companies in the field of international dust removal and desulfurization, such as SPX, Germany, and Bakdur, and signed a cooperation agreement. At the beginning of this year, the company started construction of the first complete set of desulfurization equipment production line in Liuyang Industrial Park. In just half a year, a large modern factory building of nearly 20,000 square meters was launched. Then the environmental protection equipment manufacturing center was put into operation. One year later, the center will improve the technical standards for flue gas desulfurization of thermal power plants and the mainstream process design, manufacturing, installation, commissioning, operation, maintenance and other technologies, with an annual output value of more than 2 billion yuan.
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.
