Bearing provider in China? Released on December 20, 1984 of the People’s Republic of China machinery industry standard: JB / 2300-84 the rotary bearing type, basic parameters and technical requirements, composed mainly of machinery and electronics industry of tianjin engineering machinery research institute, xuzhou hering slewing bearing factory is responsible for drafting, the country then issued standard of construction machinery in 1991: JB36.1-36.3-91, released in 1999 and 2011 successively new machinery industry standard JB / 2300-1999 and JB / 2300-2011. Slewing bearing, is a kind of comprehensive load to bear a large bearings, can withstand the larger axial and radial load and tilting moment. Find even more information at bearing manufacturer.
Joint bearing can bear larger load.According to the different types and structure, can bear radial load, axial load or the joint of the radial, axial load.Because the inside is outside the sphere with composite material, so the bearing can produce self-lubrication at work.Oscillating motion is generally used in low speed, and low speed rotation, can also be tilted movement within a certain Angle, when the supporting shaft and shaft shell hole concentricity is bigger, can still work normally.Self-lubricating bearing joints used in water conservancy, professional machinery and other industries.
Bearing is fixed in the process of mechanical transmission parts and reduce the load coefficient of friction.Its main function is to support the mechanical body of revolution, to reduce the equipment in the mechanical load coefficient of friction in the process of transmission.By the frictional properties of motion elements, bearing can be divided into two categories, the rolling bearing and sliding bearing. Most of the bearing in order to ensure stable and reliable bearing, and add the lubricating oil for lubrication, the purpose is to reduce the bearing internal friction and wear, prevent burning stick: extend the fatigue life of bearing;Friction heat, or by an external sound of hot air.
According to the material, Waxing Bearing’s products are divided into several categories, and roller bearing is one of them.Waxing Bearing carries out strict quality monitoring and cost control on each production link of roller bearing, from raw material purchase, production and processing and finished product delivery to packaging and transportation. This effectively ensures the product has better quality and more favorable price than other products in the industry. Find additional details on https://www.wxingbearing.com/.
An pillow block bearing is a bearing unit that combines a rolling bearing with a bearing housing. Most of the outer spherical bearings are made of spherical surfaces and are mounted together with imported bearing housings with spherical inner holes. The structure is diverse, versatile and interchangeable. At the same time, these pillow block bearings are also designed with a certain degree of self-alignment, easy to install, and have a double-structured sealing device that can work in harsh environments. The bearing housing is typically cast. Commonly used seats are vertical seat (P), square seat (F), boss square seat (FS), boss circular seat (FC), diamond seat (FL), ring seat (C), slider seat, etc. T).
The effort pays off. With the success of the first self-lubricating bearing, China’s self-lubricating bearing technology is becoming more and more perfect, and the service life is getting longer and longer. Since its development, the service life of self-lubricating bearings produced in China has reached more than 300 hours, ranking among the top in the world. Longxi has passed the most rigorous A-standard bearing certification of the NAVAIR laboratory, the most authoritative experimental organization in the field of self-lubricating bearings, and is the only Chinese bearing company that has obtained its certification so far.
Bearing ring (especially the outer ring) under alternating load and impact load, the stress it bears constantly exceeds the fatigue strength limit of the material, leading to the fatigue crack, and the crack eventually expands to a certain extent, leading to the fracture at the maximum stress of the parts.Generally occurs in the bearing area of the outer ring of the bearing, because the outer ring usually fits with the bearing box hole for clearance, and the bearing box body is a variable and elliptical part, which is easy to cause fatigue fracture under alternating load and impact load. Similar to fatigue fracture, when the stress on the bearing is greater than the tensile strength of the material, the inner ring cracks, usually due to improper installation, such as bearing installation tilt, resulting in partial load of the bearing, resulting in partial overload of the bearing caused by fracture;In addition, improper striking during installation caused bearing cracking and falling blocks, which is also classified as overload cracking.Most common interference when installation, and bearing fit size can also lead to large amount of interference of bearing ring crack (mainly has four row cylindrical bearing inner ring interference fit), interference is too big lead to inner ring stress is larger, especially thin cross section thickness (thickness of section < 12 mm) of inner ring, too much interference often leads to inner ring axial crack.
