Spherical Roller Bearings manufacturers 鈼?Introduction Spherical roller thrust bearings consist of a shaft washer, a race and a set of asymmetric spherical rollers. The bearing is a separable roller bearing. The cage includes the shaft washer and the spherical roller into a component. The seat ring and the component can be separated, the inner and outer rings can be installed independently. The action line of the rolling element load and the bearing axis obliquely form a certain contact angle, which can bear heavier axial load and radial load, but the radial load shall not exceed 55% of the axial load. The spherical thrust bearing has self-aligning performance, which allows the relative inclination of the shaft washer and the seat washer, which can compensate for misalignment, deflection of the shaft and deformation of the bearing seat. When the bearing bears one-way axial load, it can limit the one-way axial displacement of the bearing, so it can be used for one-way axial positioning. The spherical roller thrust bearings has large bearing capacity, small relative sliding, and high allowable speed. It needs oil lubrication when used. Bearings are suitable for working at high speed, mostly used in oil drilling rig spindles, iron and steel making machinery, hydraulic generators, vertical motors, propeller shafts for ships, tower cranes, extruders, reducers for rolling screws in rolling mills, forming machines, etc. 鈼?Bearing Series The types of the bearings include 292 series, 293 series and 294 series. 鈼?Production Details 鈼?Quality requirements for the machined surface of bearing rings 1. After quenching, the roughness of the surface that does not need to be ground should meet the requirements of the enterprise standard. 2. After turning, no forging marks (black skin, cracks, etc.), burrs, acute angles, depressions, nicks, surface wrinkles (turning tool vibration marks, pits), deep scratches and material defects are allowed on the surface. 3. After soft grinding, the scratch depth of the non-reference end face does not exceed 1/3 of the total allowance, and the scratch depth of the reference end face does not exceed 1/4 of the total allowance. The surface that is not ground after quenching should not be ground. There should be no visible burns, bumps and other mechanical damage on the surface. 4. The marking quality of the ferrule must meet the requirements of national standards and industry standards. 鈼?Bearing failure analysis method 1. Surface topography analysis methods: naked eye, macroscopic magnifying glass, stereo (or optical) microscope, scanning electron microscope (SEM) and transmission electron microscope. 2. Micro-area and surface composition analysis methods. 3. Structure, surface orientation and stress analysis: macroscopic stress analysis, microscopic stress analysis, phase structure analysis and crystal plane orientation analysis. 鈼?Vibration of Bearings During the operation of the rolling bearing, an elastic vibration system is formed due to the elastic contact between the raceway and the rolling elements. In addition, the forced vibration system caused by the manufacturing error of the bearing parts and the self-excited vibration system caused by the sliding between the bearing parts will cause the bearing vibration. In particular, when its vibrational energy is transmitted into the air, the noise of the bearing is formed. The vibration and noise levels of rolling bearings are a comprehensive reflection of the dynamic performance quality of the bearing. 鈼?FAQ (Frequently Asked Questions) Q1: How long will our the inquiry and question be answered?
