Wholesale Ball Bearings 鈼?Introduction 6216 2RS bearing is single row deep groove bearing. The bearing is characterized by high precision, high speed, low noise and long life. The precision grade of the bearing conforms to the standard GB/T 307.3-2017. The precision grade of the bearing is P0,P6,P5, etc. The P0 grade bearing can meet most of the applications, only when there are higher requirements for the shaft rotation accuracy, smooth running, speed, vibration and noise, and friction torque, the higher grade bearing is used. Bearing clearance is an important technical parameter, it directly affects the bearing load distribution, vibration, noise, friction, service life, mechanical movement accuracy and other technical performance. The dynamic load rating of bearing varies with the amount of clearance. Bearing rated load is the value of the load when the working clearance of the bearing is zero. Bearings are widely used in home appliances, motorcycles, automated office machinery, instruments, automobiles and other fields. 鈼?Production Details Steel blue brittle fracture under the temperature of the material according to the color of the material section fracture to judge, when the temperature is low dry 280 鈩? the mouth is white or yellow, 280 鈩?is purple, 300 鈩?is dark blue, 330 鈩?is light blue, higher than 330 鈩?is gray. The deformation of the rolling and expanding process is characterized by a combination of radial upsetting and circumferential direction fiber extension deformation of the ring billet, and the deformation of the ring billet is not large per one week of rotation, and its deformation is achieved by many cycles of continuous micro-deformation. Since the pressure exerted by the tool on the dry ring billet extends to the center layer of the ring in the form of pressure cone, the unit deformation resistance gradually decreases, and the metal extension of the center layer also decreases. The five factors that determine the nature of the grinding wheel are abrasive, grain size, bond, hardness and organization, which are often selected according to the following principles in production. Choose a grinding wheel with a smaller grit number for rough grinding to increase productivity. 鈼?Technical Parameters The standard of boundary dimensions is ISO 15: Rolling bearings - Radial bearings - Boundary dimensions, general plan. 6216 2RS bearing Bore diameterd80 mm Outside diameterD140 mm WidthB26 mm Chamfer dimensionrmin. 2 mm Shoulder diameter outer ringD1鈥?/p> Caliber diameter outer ringD2鈮?124.5 mm Shoulder diameter inner ringd1鈮?98.5 mm Diameter of shaft shoulderdamin. 91 mm Diameter of housing shoulderDamax. 129 mm Fillet radiusramax. 2 mm Basic dynamic load ratingCr72 000 N Basic static load ratingCor54 000 N Fatigue load limitCur3 450 N Limiting speednG4 500 r/min Reference speednB5 500 r/min Massm鈮?1.49 kg 鈼?Tolerance and Radial Clearance The standard of tolerance is DIN 620-2: Tolerances for rolling bearings.
