What is CAM bearing? CAM bearing characteristics and maintenance - bearing knowledge

CAM bearing is a bearing, has the thick outer ring needle roller bearing and bolt combination structure; Within the bolt bearing set has lubricating oil; Outside the outer surface of the cylindrical and spherical shape, could be selected according to the practical applications; When installing a bearing eccentric type is convenient and accurate location of the axis of the adjusting bolt, commonly used in automobile camshaft ( Is to control the piston engine valve opening and closing action of axis) 。 CAM bearing features: 1, the thick outer ring needle roller bearing and bolt combination structure; 2, size has a metric and inch series; Set within three bolts, bearings has lubricating oil; 4, for the convenience of installation, in the big end of bearing design with 'word' and 'hexagonal pass' wrench assembly way; 5, outside the outer surface of cylindrical and spherical shape, and can be selected according to actual applications; 6, roller type applicable and bear big load, at a lower speed; 7 when installing bearing, eccentric type is convenient and accurate adjusting bolt axis position. CAM bearing maintenance way: 1, the new CAM rotor pump put into use, must be replaced after running 100 hours (grease Oil) 1, 500 hours after each run. 2, floating bearing is lubricated by grease, run after 1500 hours, should be replaced, grease filling the oil amount is too little or too much, because too much or too little will cause bearing grease fever, amount to general in bearing chamber volume - 2/1 - - - - - - - - - - - - - - - - - - It is advisable to 2/3. 3, for bearing is lubricated by lubricating oil, the oil should be added to the specified location. 4, containers of lubricating oil or grease to clean, at ordinary times should be sealed, there should be no dust, iron and other sundry, in order to avoid damage to the bearings. 5, motor bearings with grease, this kind of ability is the feature of high temperature grease ( 125℃） , but easy to dissolve in the water, so can't use it for water pump bearing lubrication.
