Industries
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.
For mining machinery
Use parts: vibrating screen, crusher.
Representative models: 22328MB/C4W33, 22330MA/C4W33, 22328MA/C4W33.
Performance: large load, vibration resistance, high precision.

Vibration machinery
Vibration machinery usually sieves the 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, and at the same time need to have vibration resistance, low noise, and other characteristics.
Our MB and MA series spherical roller bearings are mainly used in vibrating screens.
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.
MB series of spherical roller bearing
MA series of spherical roller bearing
NJ23 series of cylindrical roller bearing
For construction machinery
Use parts: hard tooth surface reducer, fan, transmission machinery, impact crusher.
Representative models: 22322CA/C3W33, 23180CA/C3W33.
Performance: high reliability, long life, high speed, high efficiency, and energy saving.
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 R&D designed CC and CA spherical roller bearings to support corresponding crushers.
JRZC uses high-purity vacuum-degassed 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. The hardness difference of one bearing rings and rollers is less than 1HRC, a 30% higher request than the normal GB/T 34891-2017 standard.

Cone Crusher
Cone crusher is suitable for crushing raw materials in metallurgy, construction, road construction, and chemical and silicate industries. According to different crushing principles and different product particle sizes, it is divided into many models. The cone crusher has a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size. It is suitable for medium and fine crushing of various ores and rocks.
Bearing type:
Thrust cylindrical bearing

Jaw crusher is commonly known as jaw crusher, also known as tiger's mouth. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw. The crusher completes the crushing operation of materials by simulating the movement of the two jaws of animals. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy, chemical and other industries. The maximum compressive strength of the crushed material is 320Mpa.
Bearing type: spherical roller bearing series 222, 223, 231, 232 series
For example: 2 sets of movable jaw bearings 23168KC3 H3168
2 sets of main frame bearings 23256KC3 H2356
