Nine Considerations NSK Bearings use and installation process
Better not use frayed or damaged in their own vehicles or NSK bearings, NSK unit, as this may in the process of moving will give you insecurity, the worst case may cause harm to life safety. Therefore, the use of NSK Bearings use and installation process, please note the following points nine items:
First, no matter how long age of the vehicle should always check NSK Bearings, Bearings observe whether there are early warning signs of wear: including any rubbing noise when rotating or hanging combination wheel during cornering deceleration is not normal, that can ensure maximum safety and reliability. There is a rear wheel drive vehicle is recommended in the vehicle to 38,000 km is to deal with before NSK bearing lubrication. When replacing brake system, check the bearing and replace seals.
Second, in case you hear the noise is part of NSK bearings, then first you have to find the location of the noise occurs. Moving parts to generate noise for a number of reasons, it may be some of the rotating parts and no rotating parts in contact occurred. If the confirmation is bearing noise, then the bearings may be damaged and need replacing.
Third, in the transportation and installation process, the bearing parts can not be damaged. NSK Bearings more sensitive, both in the case of need to adopt the right approach and the right tools, you need special tools.
Fourth, it must be installed in a clean and tidy environment bearing or replace the bearings, because small particles from entering the bearing will shorten bearing life. Not allowed to tap with a hammer bearing note bearing can not fall to the ground (or similar improper handling). Before installing the shaft and housing should also check the status, even a small abrasion can also lead to poor coordination, can cause early bearing failure.
V. NSK Bearings unit, do not attempt to disassemble or adjust NSK Bearings NSK unit ring, otherwise it would cause water damage to seals or dust. Even ring and the inner ring raceway are damaged, causing permanent failure of the bearing.
Sixth, the bearing inner ring is equipped with ABS device has a magnetic thrust ring, thrust ring can not suffer this collision, impact or collision with other field. The correct way is: Remove from the box before installation, so that they stay away from magnetic fields, such as the use of a motor or electric tools. When installing the bearings, by the road test to observe the dashboard ABS alarm needle to change the operation of the bearing.
Seven, For vehicles equipped with ABS magnetic thrust ring of NSK bearings, thrust ring installed in order to determine which side, you can use a little something light near the edge of the bearing, magnetic bearings will be attracted to produce it. When you install the tape side pointing magnetic thrust ring inside, it is on the ABS-sensitive components.
Eight, many bearing is sealed, so these bearings in the whole life of the grease is not added. However, other non-sealed bearings such as double row tapered roller bearings in the installation must be added grease. Typically: During installation, the total amount of oil to account for 50% of the bearing clearance. Due to the different size of the bearing cavity, it is difficult to determine how much added fat, the most important is to ensure the bearing grease, if too much oil, when the bearing is rotated, excess oil will bleed.
Nine, even before the result of NSK bearing failure on both sides working conditions are similar, so if only a bad bearing, also suggested that replace them in pairs.
