Low noise INA set-contained spherical ball bearing use matters needing attention of installation and adjustment

1, low noise, INA bearing installation and adjustment of long life bearings can be in accordance with the group, make the interference, the size of the bearing clearance is also relatively consistent, as far as possible, you take the smaller values, to ensure that the raceway small deformation, therefore the rolling noise due to smaller. Clearance of bearing noise when the ideal state is the highest working temperature, zero gap value completely. When not using the above two types of low noise bearings, insert ball bearing unit can be relatively small noise. According to the specific comparison: 1) Ball bearing roller bearing of low signal-to-noise ratio, sliding bearing, Friction) The noise of the sliding bearing of the lower than; 2) Entities cage bearing noise than the relatively low ramming bearing cage using plastic use; 3) High precision bearing, especially the use of high precision roller bearings, precision bearing noise than low noise is small, 4) The noise of the small-sized bearing bearing noise than is relatively small. 2, many of the INA bearing is sealed, this kind of bearing in the whole life period is not to need to add grease. Other not seal imports bearing such as double row circular cone roller bearings must add grease lubrication during installation. Because of bearing inner cavity size is different, so it is difficult to determine how much oil, the most important thing is to make sure insert of spherical ball bearing grease, if excess oil, when bearing rotation, excess oil will seep. Experience in common: during installation, the amount of grease to account for 50% of the bearing clearance. 3, in order to ensure maximum security and reliability, it is recommended that you no matter how long their cars are often should check the wheel hub bearing - — Pay attention to whether the bearing has worn early warning signal, including any rotating friction noise or hanging abnormal combination wheel in turn. Suggestions to rear wheel drive vehicles to 38000 kilometers is the vehicle for front wheel bearing lubrication. When replacing the brake system, check the insert ball bearing unit and replace the oil seal. 4, to the wheel hub bearing unit, don't attempt to disassemble the wheel hub bearing or adjust the wheel hub unit seal, otherwise it will make the sealing ring damaged cause or dust into the water. Even the sealing ring and inner ring raceway damage, permanent failure of bearing. 5, equipped with imported ABS device sealing ring with a magnetic thrust bearing ring, the thrust ring is not influenced by the collision, impact, or a collision with other magnetic field. Take out from inside the box before installation, make them away from magnetic fields, such as using the motor or electric tools, etc. When installing the imported bearing, through the road test observation on ABS warning needle dashboard, to change the operation of INA bearings. 6, install the corresponding department, INA bearing temperature will rise sharply, the abnormal high temperature will stop running, take the necessary preventive measures. Through the lubrication, due to the temperature, speed, load, environment and the value in the table, saying only that the approximate temperature range. The fatigue life of rolling bearing and wear of friction, temperature, vibration, etc. , have a significant impact, rather than a normal lubrication bearing lubrication bearing lubrication can not work. 40% of the bearing damage is associated with poor lubrication, insert the analysis of the causes of damage of spherical ball bearing. Bearing lubrication bearing, therefore, effective measures to reduce the friction and wear.
