Worn or damaged NTN bearings or units can cause unacceptable and costly failures in your vehicle's travel path; even damage your safety. Professor of Bearing Trading Network in the use and installation of NTN bearings Remind you to focus on the following: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
1. To ensure safety and reliability for the maximum limit; advocate that you always look at the early warning signal that NTN bearings pay attention to whether the bearing can wear regardless of the age of the car: including any conflicting noise during the transition or when the suspension combination wheel is turning Unusual slowdown.
2. If you hear the murmur announced by the NTN bearing part; firstly; it is important to find the position of the murmur. There are many moving parts that can produce murmurs. It can also be that some transitions and non-transformed parts have a touch. If it is confirmed to be a bearing Noise in the middle; the bearing can be damaged; demand exchange.
3. Because the working conditions of the failure of the two sides of the front of the NTN are similar; so even if only one bearing is broken; it also advocates pair exchange.
4. NTN bearings are more sensitive. Under any circumstances, it is necessary to choose the correct method and suitable things. During the process of storage and transportation, the components of the bearing can not be damaged. Some bearings require a large pressure to press in; therefore, the demand is dedicated. thing.
5. When installing the bearing, it should be in a clean and tidy environment; the fine particles entering the bearing will also shorten the service life of the bearing. It is very important to keep the environment clean when exchanging the bearing. Do not use the hammer to strike the bearing; Dropped on the ground (or a similar disposition). The shaft and housing should also be viewed before the unit; even small wear can cause poor cooperation; then lead to early failure of the bearing.
6. For NTN bearing unit; do not attempt to disassemble the NTN bearing or adjust the sealing ring of the NTN unit; otherwise the sealing ring will be damaged and water or dust will enter. Even the sealing ring and the inner ring are damaged, forming the bearing. The eternal failure.
7, many bearings are sealed; this type of bearing is not required to add smooth grease throughout the life of the period. Other unsealed bearings, such as double row tapered roller bearings in the device, it is necessary to add grease smooth. Because the inside of the bearing The cavity is not the same size; so it is difficult to determine how much grease to add, the most important thing is to ensure that there is grease in the bearing. If the grease is too much, when the bearing changes, the remaining grease will seep out. Usually experienced: in the device; grease The total amount must account for 50% of the gap in the bearing.
