The use and installation of NTN import bearings please note

NTN import bearings or wear and tear or damage to the unit will give your vehicle in the way of driving is inappropriate and the high cost of failure, and even cause harm to your safety. In the use and installation of NTN import bearings please note the following items: 1, in order to ensure maximum security and reliability, it is recommended that you no matter how long vehicles will regularly check NTN import bearings - — 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 in the vehicle to the front of the 38000 km is NTN bearing lubrication for imports. When replacing the brake system, check the bearing and replace oil seal. 2, such as hearing NTN import bearings area noise, first of all, it is important to find the location of the noise occurs. There are many possible noise of moving parts, may also be some rotating parts and no contact with rotating parts. If confirmed is the noise in the bearing, bearing may have been damaged, need to change. 3, because the former NTN import lead to bearing failure on both sides of working conditions are similar, so even if only one bearing is broken, also recommends replacement in pairs. 4 is more sensitive, NTN import bearings, under any circumstances need to use the right methods and with the right tools. In the process of storage and transportation and installation, bearing components cannot be damaged. Need some bearing larger pressure into, so I need a special tool. Be sure to follow car manufacturing instruction. 5, when installing the bearing should be clean and neat environment, tiny particles into the bearing will shorten the service life of bearing. Replace the bearing when it is very important to maintain a clean environment. Not allowed to use hammer percussion bearing, pay attention to the bearing don't fall on the ground, Or similar misconduct) 。 Before installation should also check the status of the shaft and bearing seat, even minor wear can also lead to cooperate, that cause of bearing early failure. Unit 6, for NTN import bearings, don't attempt to disassemble the NTN import bearings or adjust the NTN import 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. 7, equipped with 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 bearing, through the road test observation on ABS warning needle dashboard, to change the bearing operation. 8, equipped with ABS magnetic thrust ring NTN import bearings, thrust ring is installed in order to determine which side, use a light small things close to the edge of the bearing, bearing of magnetic force will be attracted to it. When installation, pointed to one side of the magnetic thrust ring, is sensitive element for ABS. Note: incorrect installation may lead to the function of the braking system failure. 9, many of the bearing is sealed, this kind of bearing in the whole life period is not to need to add grease. Other not sealed 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 is the most important is the guarantee of 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.
