NSK bearings worn or damaged or the unit will keep your vehicle in the road occurs in inappropriate and costly failure, or even cause harm to your security. In installation of NSK bearing used and please pay attention to the following matters:
1, in order to ensure to the maximum security and reliability, suggested that regardless of how old you have to be regular checks of NSK bearings – attention to the early warning signals of the bearing is worn: includes any combination of friction noise when turning or flying wheels with no normal slowdown around the corner.
2, heard NSK bearing parts noise, first of all, it is important to find where the noise occurs. There are many moving parts that may produce noise, rotating and non-rotating parts may also be contacted. If you are sure it is a bearing noise, bearings may be damaged and should be replaced.
NSK causing bearing failure on both sides before the 3, because working conditions are similar, so even if a bearing is bad, it is also recommended to replace.
4, NSK bearings are more sensitive, in any case, the need for a correct approach and the right tools. In the course of storage, transport and installation, not to damage bearing parts. Some bearings require more pressure onto, so you will need special tools.
5, install the bearing should be in a clean and tidy environment, small particles into the bearing will shorten the service life of the bearing. When replacing the bearings is very important to maintain a clean environment. Percussion is not allowed with a hammer bearing, note the bearings do not fall to the ground (or improper handling are similar). Prior to installation should check the shaft and the housing situation, even minor wear may also lead to poor fit, resulting in premature failure of the bearing.
Unit 6, NSK bearings, or adjust the unit do not attempt to open NSK bearing seals, this will prevent damage to seals lead to entry of water or dust. Even ring raceway and inner ring are damaged, resulting in permanent failure of the bearing.
7, many bearing is sealed, these bearings do not require grease is throughout the entire life period. Other sealed bearings double row tapered roller bearings at the time of installation must be oil lubricated. Since the bearing cavity size different, it is difficult to determine how much oil and, the most important thing is to ensure the grease in the bearing, if too much oil, when the bearing rotates, the excess oil will ooze. A general rule of thumb: at the time of installation, amount of grease to the bearing clearance of 50%.
