Deep groove ball bearing pictures: what barbell rod bearing

Based on its professional engineering service skills, common sense, bearings, small components, but on bearing machinery and machine play an important role, as long as it is will have a bearing rotation. Even longer, second, no matter what fixes, confirmed after repair of concentricity and surface dimension is sauvy carbon nano polymer application technology of the key elements. According to the grades of technical classification of deep groove ball bearing ( Technical grade is: prompt deep groove ball bearings, representative of rolling bearings, the wide range of USES, can bear radial load and two-way axial load. Bearing wearing equipment in the process of long-term operation of bearing temperature, at the same time bear axial force and radial force, causing interference between shaft and bearing fitting clearance size metal fatigue and appear, make produce between bearing and bearing a relative motion and aggravate the wear, and the quality problem of the bearing itself lubrication in the process of the use and maintenance does not reach the designated position, also easy to cause the bearing wear. Before some post code with basic code separated by dots, SP - — Dimension precision is equivalent to level, rotary precision is equivalent to level ( Double row cylindrical roller bearing) 。 On-site repair precision through several link staff: depend on the size of the datum ( Before and after the shoulder) The special mold ( See figure repair worn parts, ensure the repair parts of the concentricity; Depend on the release agent to ensure that the repair parts of the mould size and roughness; Depending on the material itself has the compressive strength, bending resistance, temperature and oil resistant performance to ensure that the material of good usability. Waviness is caused due to vibration in the process of grinding, as a result, the research of the relationship between vibration and degree of dermatoglyph as well as the causes of vibration is very necessary. Thickener is a mixture of sodium calcium soap and soap, drop point ~ ℃, penetration to mm, weak water resistance in calcium base grease, allow the water vapour or work in damp environment and working temperature for ~ ℃, not suitable for low temperature. In strong magnetic environment, the use of steel bearings, powder itself from bearing wear down by adsorption between the roller and the rolling surface, this will be a bearing of the main causes of early spalling damage and increase noise. Within the bearing seat is equipped with two axle bush above, assuming that A and B on both sides of the vertical vibration in phase, if A and B with the same on both sides of the bearing stiffness, radial vibration will not stimulate the axial vibration. Compact structure, simple assembly, bearing retainer on the welder welding efficiency is high, the welding process, in seconds, The section about) and docking, , far higher than of arc welding welding way. Carefully investigate and record the bearing and the appearance of being removed, in order to explore the residual amount of investigation and lubricant, after sampling, to wash the bearing very well.
