Double taper roller Roller bearings manufacturer in China? 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.

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.
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.

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.
Bearing structure and service conditions.Different structures are suitable for different service conditions;The processing technology of bearing parts is not the same with different structures, which affects its quality.Therefore, we should develop new structural products to adapt to different service conditions, and can indicate its suitable service conditions or performance on the bearing instructions, in order to facilitate the choice of customers. Strengthen process research, improve processing technology, improve processing quality, and reduce the possibility of defects in processing.For example, on the heat treatment, for the larger varieties of inner and outer rings, try to use the lower limit quenching heating temperature, adapt to extend the insulation time, to improve the alloying concentration, increase the breaking strength of martensite, and on the premise of ensuring the quality of high tempering temperature to enhance the impact toughness of the workpiece.
As a technology pioneered by developed countries such as the United Kingdom, self-lubricating bearings are naturally the same as high-end technologies in other manufacturing fields, which have imposed a technical blockade on my country. For a long period of time, my country has to pay no small price in the face of self-lubricating bearings. In this regard, He Liangjia, the head of Fujian Longxi Bearing, said: Foreigners can, but why can’t China? There is nothing impossible in this world. Under this belief, the research team of China Bearings started the research work on self-lubricating bearings without any equipment support and theoretical and technical foundation.
