Wheel hub KOYO bearing installation, use common sense - bearing knowledge

Car wheel hub bearing in the past the most were using single row tapered roller or ball bearing in pairs. With the development of technology, cars are already widely used car wheel hub unit. The use of the wheel hub bearing unit and usage is growing, at present has developed to the third generation: the first generation consists of double row angular contact bearings. The second generation of rolled out on a used to KOYO bearing fixed flange, can be simple to KOYO bearing sleeve to the shaft with a nut. Make car maintenance becomes easy. The third generation wheel hub bearing unit is adopted KOYO bearing unit and the holding brake system. Wheel hub unit designed to have the flange and the outer flange, the flange bolts fixed on the driven shaft, flange outside the whole KOYO bearing installed together. Worn or damaged wheel KOYO bearings or wheel hub 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 of the wheel hub bearing and install 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 wheel KOYO bearings - — Note KOYO bearings have worn early warning signal, including any rotating friction noise or hanging abnormal combination wheel in turn. Suggestions to rear wheel drive vehicles to 38000 kilometers is the vehicle for front wheel KOYO bearing lubrication. When replacing the brake system, check the KOYO bearings and replace the oil seal. 2, such as hear the wheel hub bearing area of 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 KOYO bearings, KOYO bearings may be damaged, need to change. 3, because the front wheel to KOYO bearing failure on both sides of the working conditions are similar, so even if broken only a KOYO bearings, also recommends replacement in pairs. 4, wheel hub bearing is more sensitive, under any circumstances need to use the right methods and with the right tools. In the process of storage and transportation and installation, KOYO bearing components cannot be damaged. Some KOYO bearing need larger pressure into, so I need a special tool. Be sure to follow car manufacturing instruction. 5, when installing KOYO bearings should be in clean and tidy environment, tiny particles into the KOYO bearing will shorten the service life of KOYO bearing. Replacement of KOYO bearing when it is very important to maintain a clean environment. Not allowed to use hammer percussion KOYO bearing, pay attention to KOYO 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 early failure of KOYO bearing. 6, to the wheel hub bearing unit, don't attempt to disassemble the wheel hub KOYO bearing or adjust the wheel hub 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, KOYO bearing permanent failure. 7 device, equipped with ABS KOYO 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 KOYO bearings, through the road test observation on ABS warning needle dashboard, to change operation of KOYO bearing. 8, equipped with ABS wheel hub bearing of magnetic thrust ring, in order to determine the thrust ring pack what side, use a light small things close to the edge of KOYO bearings, KOYO bearings produced by the 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 KOYO bearings are sealed, this kind of KOYO bearing in the whole life period is not to need to add grease. Other don't seal KOYO bearing such as double row circular cone roller bearings must add grease lubrication during installation. Due to KOYO bearing inner cavity size is different, so it is difficult to determine how much oil, the most important is the guarantee of KOYO bearing grease, if excess oil, when KOYO bearing rotation, excess oil will seep. Experience in common: during installation, the amount of fat to 50% of KOYO bearing clearance. 10, installing a lock nut, due to the different KOYO bearing type and bearing torque size difference is very big. Note with reference to relevant specifications.
