    ESE joint bearing is mainly composed of a spherical inner ring and an outer ring bearing the special structure of the inner spherical surface. Can withstand a greater load.
    Brief introduction
    ESE joint bearing structure simpler than the rolling bearing, which is mainly composed of an inner and outer sphere within a spherical outer ring. ESE Bearings are generally used for lower-speed swing motion (ie angular motion), the sliding surface of the spherical shape, but also for the tilt angle within a certain range of motion (ie, aligning movement), except in the support shaft and the shaft housing bore When the heart of a large, still work properly.
    Feature
    ESE joint bearings can withstand a greater load. According to their different types and structures to withstand radial load, axial load or radial, axial joint load. Since the inner surface of the outer sphere inlaid with composite materials, so the bearings can be produced in the work of self-lubricating. Generally used for lower-speed swing motion, and low-speed rotation, but also for a certain tilt angle range of motion, while supporting shaft and housing bore axis misalignment is large, can still work. ESE self-lubricating bearing joints used in water conservancy, specialized machinery and other industries.
    Application
     ESE ESE self-lubricating bearings joint bearings are widely used in hydraulic engineering, metal forming machine tools, engineering machinery, automation equipment, automotive shock absorbers, irrigation machinery and other industries. ESE joint bearing is spherical plain bearings, the basic type is within the spherical sliding spherical contact surface of the outer ring. Depending on the structure and type, can withstand the radial load, axial load, or radial, axial joint load.
    Because spherical plain bearings sliding contact ESE area, tilt angle, but also because most of ESE joint bearing take special process method, such as surface phosphate, zinc, chrome or outside the sliding surface lining, insert pad, spray etc. Therefore, greater load capacity and impact resistance, and has anti-corrosion, wear resistance, self-aligning, self-lubricating lubrication or no lubrication good dirt pollution characteristics, even dislocation can be installed to work properly. Therefore, ESE joint bearings are widely used for lower-speed swing motion, tilt movement and rotation.
    Composition
    ESE mainly by a joint bearing outer ring and an inner components. Spherical outer ring and the inner ring of the composition of the inner spherical surface rolling friction.
    ESE joint bearing performance
    ESE bearing joints due to the form and structure of the working mechanism of the Rolling ESE bearing joints completely different, so ESE bearing joints has its own technical characteristics and maintenance requirements.
    Operating temperature 
    ESE bearing joints allow the working temperature is mainly determined by the material pairing between the bearing sliding surfaces, especially plastic material sliding surface ESE self-lubricated bearing joints, its carrying capacity at high temperatures have decreased. When the sliding surface material bearing joints lubricated ESE pairing of steel / steel, the allowable operating temperature depends on the permissible operating temperature of the lubricant. But for all the lubrication type and self-lubricated bearing joints ESE concerned, may, within -30 ℃ ~ + 80 ℃ temperature range, and maintaining the correct tolerance.
    Dip
    ESE bearing joints are generally much larger than the Rolling adjustable inclination of the heart, it is suitable for use in demanding concentricity supporting parts, ESE angle with the form of joint bearing bearing structure size, type, sealing means and the support varies inclination range ESE generally spherical plain bearings is 3 ° ~ 15 °, inclination range ESE angular contact bearings is 2 ° ~ 3 °, inclination range ESE thrust bearings are 6 ° ~ 9 °.
    Coordinate
    In any case, ESE bearing joints shall be chosen so that the ferrule with uneven deformation occurs, with the nature and level of their choice must be determined according to bearing type, load bearing form and size of the working conditions.
    Handling
     ESE ESE joint bearing joint bearing handling should follow the principle that the force exerted by the assembly and disassembly can not directly pass through the spherical sliding surface. In addition, you should use an auxiliary handling tools, such as a sleeve puller, etc., outside the loading force applied directly and uniformly applied to the mating ferrule, or other auxiliary heating methods no-load handling.
    Installation
    When assembling the ESE joint bearing series, it is necessary to pay special attention to the position of the outer surface of the split. In order to avoid compliance with a direct role in the split face, the need to maintain and meet the dividing plane at right angles to the direction.
    Lubricating
    When the applied load and speed oscillating movement generated very hour, ESE to oil-bearing joints can be operated without lubrication conditions. Nevertheless, under normal circumstances must be replenished periodically grease. Operation during the initial installation, it is recommended lubrication intervals need moderately reduced.
    ESE no case to oil-lubricated bearing joints can no longer use under. However, if before the operation was added lithium soap grease life ESE bearing joints can speak more extended. If the grease around the bearing space, ESE bearing joints will be more effective protective dust and foreign matter invasion.

    ESE bearing joints mechanical properties calculation methods
    Spherical Plain Bearings ESE contact surface (spherical plain bearing) has two "fit" of such contacts is called coordination contacts. ESE joint bearing structure design method for calculating mechanical properties and wear ESE bearing joints analysis plays an important role. Calculation coordinate surface contact pressure is a very complex issue, because the limited existing Hertz model elastic half-space, can not be used to calculate the spherical coordinate the contact pressure distribution. There are already a spherical contact unified model, namely Fang model, can solve the problem of small deformed spherical contact pressure distribution, this model for non-contact and coordination coordination contacting apply. But the contact area ESE of spherical plain bearings is not complete, calculate the contact pressure distribution calculated on the basis of the need for further contact with the complete coordination sphere model. In addition, the process of using ESE bearing joints also appear free boundary effects, for bearing joints ESE applications will have some impact. Free boundary effect contact pressure generated in the bearing outer edge ESE joint focus and greater pressure gradient.
