Bearings factory in China? As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used. Slewing bearing is nearly forty years worldwide emerging new type of mechanical parts, it is composed of inner and outer ring, rolling body, etc, finalize the design production of slewing bearing in China, mainly in the early 80 s by the ministry of machinery industry in tianjin institute of engineering machinery group introduced the former federal republic of Germany Rothe Erde design and manufacturing technology of the company.

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.
At the same time, the oil film also has a certain vibration absorbing ability.Add the lubricating oil, however, one of the biggest disadvantage is need good sealing performance, otherwise it will leak, and some have special requirements equipment lubricating oil leakage is not permitted, so people with other lubrication material to replace the lubricating oil, the invention bearing without oil, make it not only possesses the advantages of containing oil bearing, at the same time to eliminate the environmental pollution caused by leakage.
One-way bearing is free to rotate in a direction, and locked in another direction of a bearing.One-way bearing is also called the overrunning clutch, just according to different industries, the effect is different.One-way bearing metal shell, contains a number of roller, needle or ball, and the rolling (hole) of the shape that it can only scroll in one direction, while in another direction will produce very big resistance (the so-called “one-way”). Powder metallurgy one-way bearing by moulding and sintering process the metal powder (or the mixture of metal powder and nonmetal powder) made products of technology.In the study of the characteristics of powder and process variation characteristics, on the basis of the corresponding technical process, changing the shape of powder, performance, and their organization structure as to adapt to the different needs of bearing products.

Needle bearing with fine and long roller,so the radial structure is compact,its diameter and load capacity at the same time,with other types of bearing outside diameter to a minimum,especially suitable for the limited size of the radial installation supporting results. Needle roller bearing capacity big,applicable to the limited size of installation supporting structure,the journal as rolling surface hardening on the surface,bearing force fit in a hole,not for axial positioning.Needle roller bearing according to the use of different occasions,the machining accuracy and surface quality should be combined with bearing ring,use.Needle roller bearing is a centripetal needle bearing and thrust bearing parts of the bearing unit.
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.
