Lubricant is an essential and necessary condition for bearings during operation, and it is an important adjustment to reduce bearing wear and improve bearing life. The lubrication methods of imported bearings can be divided into grease lubrication and oil lubrication. Different imported bearings, different usage methods, and the lubrication methods used are also different. Below, Demeri Bearing will share with you the impact of the selection of imported bearing lubricating oil on bearings.

Lubrication has a significant impact on the fatigue life, friction, wear, temperature rise, vibration, etc. of imported eccentric bearings. Without normal lubrication, eccentric bearings cannot function. Analysis of the causes of damage to vibration eccentric bearings shows that about 40% of vibration bearing damage is related to poor lubrication.
The lubrication methods for vibration eccentric bearings are divided into grease lubrication and oil lubrication. In order to make the bearings function well, first of all, it is necessary to choose a lubrication method that is suitable for the conditions and purpose of use. If only lubrication is considered, the lubricity of oil lubrication is advantageous. However, grease lubrication has the advantage of simplifying the surrounding structure of bearings.
1. Eccentric bearing grease lubrication
Lubricating grease is a lubricant composed of base oil, thickener, and additives. When choosing, it is important to choose lubricants that are very suitable for the conditions of use of eccentric bearings. Due to different varieties, there will also be significant differences in performance. Therefore, attention must be paid when choosing.
2. Eccentric bearing oil lubrication
Under high-speed and high-temperature conditions, oil lubrication can be used when grease lubrication is no longer suitable. By circulating lubricating oil, a large amount of heat can be carried away, and it is also effective in reducing eccentric bearing vibration and noise.
3. Oil viscosity of eccentric bearings
The viscosity of imported bearings is an important characteristic of lubricating oil, and its magnitude directly affects the fluidity of the lubricating oil and the thickness of the oil film formed between the friction surfaces. The viscosity of lubricating oil at the working temperature of vibration eccentric bearings is generally 12-15cst. The higher the rotational speed, the lower the viscosity should be chosen, while the heavier the load, the higher the viscosity should be chosen· Commonly used lubricating oils include machine oil, high-speed machine oil, turbine oil, compressor oil, transformer oil, cylinder oil, etc.
Reasonable use of lubricating oil during the storage and operation of imported bearings can reduce bearing wear and enhance their service life.

Disassembly method of needle bearing
The knocking force is generally applied to the inner ring of the bearing, and the knocking force of the shielding machine room should not be applied to the rolling element and cage of the bearing. This method is simple and easy to operate, but it can easily damage the bearing. When the bearing is located at the end of the shaft, use a copper rod or other soft metal material smaller than the inner diameter of the bearing to support the shaft end, and add a cushion block to the lower part of the bearing. Gently tap with a hammer to remove it. When applying this method, attention should be paid to the appropriate position of the cushion blocks and the correct point of application.

Application of tapered roller bearings
Tapered roller bearings have tapered inner and outer raceways, with tapered rollers arranged between them. The projection lines of all conical surfaces converge at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing composite (radial and axial) loads. The axial load capacity of bearings is mostly determined by the contact angle α Determined; α The larger the angle, the higher the axial load capacity. The angle size is represented by the calculation coefficient e; The larger the e-value, the greater the contact angle, and the greater the applicability of the bearing to withstand axial loads.

The dismantling of bearings is a regular maintenance process, which is carried out during bearing replacement. After disassembly, if it is necessary to continue using or check the condition of the bearings, the disassembly should also be carried out with the same care as during installation. Pay attention not to damage the various parts of the bearing, especially the disassembly of interference fit bearings, which is difficult to operate.

Method for Adjusting the Radial Clearance of Cylindrical Roller Bearings
For multi oil wedge tilting bearing pads, it is not allowed to repair or scrape the pads. When the clearance is not suitable, the pads should be replaced. For pads with adjustable thickness, the amount of pads can be adjusted by adding a stainless steel pad under the adjustment block at the back of the pad, or by thinning the thickness of the adjustment block. Note that for multi oil wedge tilting bearing pads, the thickness error between the same set of pads should be less than 0.01mm.
