Joint Bearing


Product Name: Joint Bearing


Address: Qianmu Village, Yingchengzi Town, Ganjingzi District, Dalian, China.

Description: Joint BearingProduct introductionThe structure of joint bearing is simpler than that of rolling bearing, which is mainly composed of an inner ring with an outer sphere and an outer ring with an inner sphere. Knuckle-bearing is generally used for low-speed swing movement (i.e. angular movement). Because the sliding surface is spherical, it can also be tilted in a certain Angle range (i.e. centering movement), and it can still work normally when the hole of supporting shaft and shaft shell is not concentric.Product featuresThe joint bearing can bear heavy load. According to its different type and structure, it can bear radial load, axial load or combined radial and axial load. Because the outer sphere of the inner ring is inlaid with composite material, the bearing can produce self-lubrication in operation. It is generally used for low-speed swing movement and low-speed rotation, and it can also make tilt movement in a certain Angle range. When the supporting shaft and the shaft shell hole are not concentric, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.Product useJoint bearing is widely used in engineering hydraulic cylinder, forging machine tool, engineering machinery, automation equipment, automobile shock absorber, water conservancy machinery and other industries. The joint bearing is the spherical sliding bearing, the basic type is by has the spherical sliding spherical contact surface inner and outer ring composition. Depending on its structure and type, it can bear radial load, axial load, or a combination of radial and axial loads.Because joint bearing spherical sliding contact area is large, slope Angle is large, but also because most of the joint bearing adopted special processing methods, such as surface phosphating, galvanized, chrome plating, or outside sliding surface lining, padded, spraying, etc., so the larger load capacity and impact resistant ability, and have the corrosion resistance, wear resistance, can make, good lubrication and self-lubricating without lubrication characteristics of sewage pollution also can work normally even install dislocation. Therefore, joint bearings are widely used in low-speed swing, tilt and rotary motion.Four, processing technology(1) forging linkForging link is an important link to ensure the reliability and service life of joint bearing. At the same time, the structure of the raw material becomes denser and the flow linear becomes better, which can improve the reliability and service life of the joint bearing. In addition, the quality of forging process will also directly affect the utilization rate of raw materials, thus affecting the production cost.(2) heat treatmentHeat treatment is to treat the forged and processed joint bearing rings at high temperature. It directly affects the uniformity of carburizing in the joint bearing rings, can improve the wear resistance and hardness of joint bearing, and is also an important part that affects the reliability and life of joint bearing.(3) grinding processing linkAfter heat treatment, the ring of joint bearing needs to be grinded, which is an important part to ensure the precision of joint bearing. After grinding, the production process of joint bearing ring is basically completed.Joint bearing ring processing processBearing inner ring and outer ring of the whole process is: car processing, heat treatment, grinding, grinding or polishing parts – final inspection – rust – storage – (stay close set of assembly >
