Which bearings are usually used for mining machinery?
The mining machinery industry is one of the important basic industries that provide equipment for the mining and processing of solid raw materials, materials, and fuels. It is also widely used in the capital construction of basic sectors such as railways, buildings, water conservancy, and hydropower.
The professional machinery and equipment that are widely used in mining operations can be roughly divided into mining equipment, mineral processing equipment, and prospecting equipment. Mining machinery refers to machinery that is directly used for mineral mining and beneficiation, including mining machinery and mineral processing machinery. The working principle and structure of prospecting machinery are mostly the same or similar to mining machinery, and it is also a kind of mining machinery in a broad sense. A large number of cranes, conveyors, fans, and drainage machinery are also used in mining operations.
At present, the most used rolling bearings in the mining machinery industry are spherical roller bearings, which are mostly used in jaw crushers, impact crushers, vibrating screens, and feeders. Angular contact ball bearings and cylindrical roller bearings are used in impact crushers. Tapered roller bearings are mostly used in mills and other equipment.
The main bearing of the cone crusher basically adopts the sliding bearing (copper sleeve), and the single-cylinder cone crusher drive shaft mostly adopts the rolling bearing.
Our MB and MA series spherical roller bearings are mainly used in vibrating screens.Vibration machinery，usually sieve body with high vibration for the material screening，in order to meet the vibration application,the bearings need to bear more load than the corresponding standard bearing,at the same time need to have vibration resistance,low noise and other characteristics.
According to the actual working conditions of vibration machinery,JRZC mainly produces vibration machinery bearings,including MA and MB structure.
Application:vibrating screen,223xx whole series bearings have been massively produced.
JRZC R&D design CC and CA spherical roller bearings to support corresponding crushers. Impact crusher: The impact crusher can process materials with a side length of 100-500 mm or less, with a compressive strength of up to 350 MPa, with a large crushing ratio, and the crushed materials are cubic particles. Widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries for medium and fine crushing materials. The size of the discharge particle size can be adjusted, and the crushing specifications are diversified.High efficiency reaction crusher,mainly used in the second and third level fine crushing process,high crushing efficiency,high efficiency and energy saving.
JRZC use high purity vacuum degased bearing steel as raw materials,so as to ensure bearing quality from the very beginning.Aichelin salt bath heat treatment for the ring and rollers contribute to stable quality.Hardness difference of one bearing rings and rollers is less than 1HRC,30% higher request than the normal GB/T 34891-2017 standard.
