Roller bearings factory with wxingbearing.com? 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. See extra details at custom bearing manufacturer.
Joint bearing is a kind of spherical sliding bearing, the sliding contact surface is an inner spherical surface and an outer sphere, rotary oscillation motion can be in any Angle, it USES the surface phosphating, Fried, padded, spraying and other special craft processing method.Joint bearing with large load capacity, impact resistance, corrosion resistance, wear resistance, from the heart, good lubrication, etc. Joint bearing structure than the rolling bearing is simple, its mainly by a spherical within the inner ring and a spherical outer ring.Joint bearing is generally used in low speed of the swinging motion (that is, the angular motion), due to the sliding surface of spherical shape, can be tilted movement in certain Angle range (that is, the heart movement), the supporting shaft and the shaft shell hole concentricity is bigger, can still work normally.
Oilless bearing is a kind of both metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, the load matrix, and the special formula of solid lubricating materials lubrication.It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion.
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.
Many people may wonder about this. In everyone’s traditional knowledge, one of the most critical functions of bearings is to reduce friction, and lubricating oil is the key to keeping parts lubricated. How can bearings that lack lubrication ensure their service life? What about the degree of lubrication? From this point of view, the relationship between bearings and lubricating oil seems to be inseparable. The only way to avoid the adverse effects of lubricating oil on machinery seems to be to seal as much as possible. But Bai Mi is always sparse, and there is no perfect perfection in the world. No matter how well the sealing work is done, it is always difficult to avoid leakage problems. The only effective way is to abandon the use of lubricating oil.
Fracture is mainly due to the hot and bearing ring end face with sliding friction between parts, under the action of axial force, frictional heat, producing the end face burned with color changing conditions, such as friction and heat that causes bearing ring end face crack, crack characteristics is perpendicular to the direction of friction work, also transverse crack of cross section thickness thinner (thickness of section < 12 mm) had a greater influence on the inner ring, especially overloaded high or medium speed mill roller bearing. Here, we should pay attention to the fatigue fracture and overload fracture of bearing rings may occur at the same time, especially for bearings with poor service conditions (such as 22328, etc.).The research on the phenomenon of ring fracture should not only consider from the point of view of the defects produced in the material and production process, but also study and analyze the structural size of bearing parts, processing measurement means, processing technology, bearing service conditions and other factors.
