1, low noise INA bearing of the installation and adjustment of the long life bearing can be in accordance with the group, the size of the interference consistent, bearing clearance is also more consistent, you must be interference, take the smaller value, ensure that groove distortion, and rolling noise caused by smaller.
 
The noise of the space and the ideal state of bearing is the highest working temperature condition, completely zero gap value. When not using the above two types of low noise bearings, ball set-contained bearing can be relatively small noise. According to the concrete is:
 
1) ball bearing roller bearing the signal-to-noise ratio of the low, sliding bearing (friction) sliding bearing noise than is lower;
 
2) entity maintains a bearing noise than low relative stamping bearing maintains a use plastic use;
 
3) high precision bearings, especially with higher precision roller bearings, precision bearing noise more than low noise is small, and
 
4) the noise of the small small-sized bearing than the relatively small bearing noise.

2, the INA bearing many is sealed, this kind of bearing in the whole life cycle is not to need to add the grease. Other not sealed import bearing such as double row circular cone roller bearings in the installation must add grease lubrication. Since the bearing inner cavity of different sizes, so it is difficult to determine how much oil, the most important is to guarantee the set-contained ball bearings in oil, if too much grease, when bearing turns, excess oil being. General experience: in the installation, the amount of oil to account for 50% of the clearance of the bearing.

3, for maximum ensure safety and reliability, suggest you no matter how long the age of car will often check hub bearings--note bearing whether early warning signal wear: including any turns the friction of the noise or suspension combination wheel in turning the slowdown is not normal.
A rear wheel drive car Suggestions to the vehicle to 38000 kilometers before is coping with wheel bearing lubrication. When replacement brake system, check the set-contained ball bearings and replace the oil seal.

4, wheel hub bearing unit, don't try to untangle hub bearings or adjust the wheel hub unit of the sealing ring, or you will make sealing ring in water or damaged dust entering. Even sealing and inner circle of groove are damaged, causing permanent bearing failure.

5, equipped with imported ABS device of the bearing seal there is a magnetic thrust ring, the thrust ring cannot be collision, impact or and other magnetic field collide. Before installation out from inside the box, let them away from magnetic fields, such as the use of motor or electric tools, etc. Install the import bearings, through the road test observation dashboard ABS alarm needle, to change the INA bearing operation.

6, installation corresponding department, INA bearing temperatures will rise fast, can appear abnormal high temperatures stop running, take the necessary precautions. Through the lubrication, as temperature, speed, load, the environment, to the table of numerical, said only approximate temperature range. The rolling bearing fatigue life and friction and wear, temperature, vibration, etc, it has great influence, not the normal lubrication bearing the lubrication bearing lubrication cannot work. 40% of the bearing damage and bad lubrication relevant, set-contained ball bearing the cause of damage analysis. Therefore, bearing by reducing friction and lubrication bearing of wear effective measures.
