YOCH Bearing

When the IKO bearing rotates, the raceway surfaces of the inner and outer rings of the thrust ball bearing are in rolling contact with the rolling elements, so the running track is dark. It is not abnormal for the running track to be attached to the raceway surface. From this, the load conditions can be known. Therefore, when disassembling the bearing, please pay close attention and observe the running track of the raceway surface.

Oil-free lubrication or low-oil lubrication is suitable for places where refueling is impossible or difficult, and can be used without maintenance or with little maintenance.

Self-lubricating bearings are now mainly divided into two series, oil-free lubricated bearing series and boundary lubricated bearing series. So what are the main characteristics and advantages of self-lubricating bearings during use?

Approximately 25% of all premature koyo bearing failures are caused by improper installation or incorrect use. Various applications may require heating, mechanical or hydraulic installation methods to properly and efficiently install automotive wheel hub bearings. Selecting the right installation method for the application will help extend the life of the bearing and reduce the cost of premature bearing failure and potential damage to the application.

In the past, most of the wheel hub bearings for cars were used in pairs of single-row tapered rollers or ball bearings. With the development of technology, car hub units have been widely used in cars. The scope and amount of use of wheel hub bearing units are increasing day by day, and they have now developed to the third generation: the first generation is composed of double-row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply be put on the axle and fixed with nuts. This makes the maintenance of the car easier. The third generation of wheel hub bearing units uses a bearing unit and an anti-lock brake system. The wheel hub unit is designed with an inner flange and an outer flange. The inner flange is bolted to the drive shaft, and the outer flange installs the entire bearing together.

The inspection of TIMKEN bearings should be carried out under a diffuse light, and the appearance, cracks and other parts of the TIMKEN bearings should be carefully observed.

The belt is too tight or the coupling is poorly assembled and in a bad state. Here you can adjust the belt tension and calibrate the coupling for repair.

Rolling INA bearings are classified according to the type and number of rows of rolling elements, the direction of the load they can bear, and whether they have automatic self-aligning function.

At the friction points between the crankshaft and the bearings, the crosshead and the slide plate, the packing and the piston rod, etc., the temperature exceeding the specified value is called overheating. The consequences of overheating: one is to accelerate the wear between the friction pairs, and the other is that the heat of the overheating continues to accumulate until the friction surface is burned and the lock is burned, causing major machine accidents. The main causes of bearing overheating are: uneven fit between the bearing and the journal or too small contact area; deflection of the bearing, bending and twisting of the crankshaft; too low viscosity of the lubricating oil, blockage of the oil circuit, failure of the oil pump, etc.; during installation There is no leveling, no clearance is found, the main shaft and motor shaft are not aligned, the two axes are tilted, etc.
